InterVLAN routing problem

Hi friends,

I have a question related to the Inter-VLAN routing. I have 2 switch a 3850 L3 and another is 2960 L2 (Pure L2). I even vlan on both switches and IP routing enabled on switch L3. But not woking switch l3 to L2 Intervlan Routing switching systems.

Deepak Kumar

I think that Reza questions 3 and 4 are more important than questions 1 and 2, but perhaps do not go quite far enough. The two switches to assign certain ports to a vlan specific and use the vlan by default for most of the ports. There are no statements on a switch which create the vlan but only statements that a port must Access a specified VLAN

interface FastEthernet0/1

switchport access vlan 7

On some versions of switches that may be enough to create the vlan, but on other switches, it is necessary to create the vlan before using it. Maybe something like

VLAN 7

name server_vlan

I would ask if the VLAN on each switch existence?

There is another question in this config. The switches have created more than 3 VLANs (vlan 1 - the vlan by default and vlan 2 and vlan 7.) But the L3 switch configured more than one interface vlan (3, 4, 5, 6, 8, 9). Without a vlan underlying pertaining to these layer 3 interfaces vlan will not work.

  • Cisco SG300 / ASA 5505 intervlan routing problem

    Dear all

    I have a problem with the configuration correctly sg300 layer 3 behind the ASA 5505 switch (incl. license more security)

    The configuration is the following:

    CISCO SG300 is configured as a layer 3 switch

    VLAN native 1: 192.168.1.254, default route ip address (inside interface ASA 192.168.1.1)

    VLAN defined additional switch

    VLAN 100 with 192.168.100.0/24, default gateway 192.168.100.254

    VLAN 110 with 192.168.110.0/24, default gateway 192.168.110.254

    VLAN 120 with 172.16.0.0/16, default gateway 172.16.10.254

    Of the VLANS (100,110,120) different, I am able to connect to all devices on the other VIRTUAL local networks (with the exception of Native VLAN 1; is not the ping requests)

    From the switch cli I can ping my firewall (192.168.1.1) and all the other gateways of VLANs and vlan (VLAN1, 100, 110, 120) devices

    Asa cli I can only ping my switch (192.168.1.254) port, but no other devices in other VLAN

    My question is this. What should I change or installation in the switch configuration or asa so that other VLANs to access the Internet through the ASA. I will not use the ASA as intervlan routing device, because the switch does this for me

    I tried to change the asa int e0/1 in trunkport (uplink port switch also), to enable all the VLANS, but as soon as I do that, I can not ping 192.168.1.254 ASA cli more.

    Any help is greatly appreciated

    Concerning

    Edwin

    Hi Edwin, because the switch is layer 3, the only necessary behavior is to ensure that default gateways to the computer are set on the SVI interface connection to the switch to make sure that the switch is transfer traffic wished to the ASA.

    The configuration between the ASA and the switch must stay true by dot1q, such as the vlan all other, unidentified native VLAN tagged.

    Also, if I'm not wrong, on the SAA you must set the security level of the port to 100.

  • [SOLVED] Problem with the ACB and InterVLAN routing

    Hello.

    I have Cisco 3750 G with IOS k9 - mz.150 - 2.SE4 Service of intellectual property. In my network, I have 4 VLANs with 4 internet gateways. I have set 4 static route for each gateways and with PBR to match this static routes. If I use "set ip next-hop" all traffic goes through the specific gateway interVlan routing does not work (I need to because the customers interVlan routing in different VLANS must be), and if I use 'set ip default next-hop', I was incapable of it attributed to Vlan (road-map lan14 not supported based on routing strategies).

    Model SDM is on the road that ip Routing is enabled.

    Please help me, I'm stuck here almost three weeks.

    Hello

    You have created courses 2-card to set the next hop for a portion of the traffic classified with an acl.

    If you want any other traffic manager you must create an empty instance of your roadmap

    Example:

    lan7 allowed 10 route map

    football game...

    map of route allowed lan7 20 ==> Add this instance and leave it empty. You say the switch/router that he must refrain from other traffic but nothing to apply.

    Hope that this clear.

  • InterVLAN routing for S4810 VLT

    Hello

    I just want to clarify things because I get confused all intervlan routing if it is possible to implement if I used VIDEO Lottery devices

    First of all when I configured the VLT field in sweetheart two switches (S4810), I need to have an itinerary for my VLAN

    -what I used intervlan routing is my favorite, but when the peer routing, active in VLT intervlan routing is applicable or supported in routing peers. ?

    -also all configurations of the two peer switches must be identical or same

    • example: when I configured intervlan routing in Peer-1, also, I need to configured intervlan routing in Peer - 2

    I want to have an answer if I need intervlan or OSPF configuration with this problem

    Thank you very much

    BRENT

    This technical guide I think answer all your questions. Yes, you can have VLAN routing enabled on the switches. The guide goes through many examples, including examples of switches that is configured to perform the VIRTUAL LAN routing. It also includes examples of configuration that you can use as a reference.

  • LRT214 InterVLAN routing databases

    Could someone understand me, what "InterVLAN Routing" setting (under management port > 802 1 q LAN) actually did or influence?

    It's a bit tedious to find trying and the manual, which is essentially a textual serialization of interfaces Web (kind of pointless), doeosn can't help much.

    It is just a shortcut for firewall access rules, or influence it something else? I can get between the VLANS with access for people with disabilities, and appropriate rule set. However, I have however a strange behavior.

    Anyone know?

    Firewall access rules can override the settings of the inter-VALN. Without the two access rules, hosts VLAN1 will not be able to access hosts in VLAN8 and vice versa.

  • Routing problem between the VPN Client and the router's Ethernet device

    Hello

    I have a Cisco 1721 in a test environment.

    A net 172.16.0.0/19 simulates the Internet and a net 192.168.1.0/24 simulates the net, the VPN tunnel must go to (intranet).

    The net 172.16.0.0 depends on the router 0 FastEthernet, Intranet (VPN) hangs on Ethernet 0.

    The configuration was inspired form the sample Configuration

    "Configuring the Client VPN Cisco 3.x for Windows to IOS using Local extended authentication"

    and the output of the ConfigMaker configuration.

    Authentication and logon works. Client receives an IP address from the pool. But there's a routing problem

    side of routers. Ping client-side - do not work (the VPN client statistics that count encrypt them packets, but not to decrypt).

    Ping the router works too, but decrypt and encrypt customer statistics in VPN packets count progressive

    (customer has a correct route and return ICMP packets to the router).

    The question now is:

    How to route packets between the Tunnel and an Ethernet device (Ethernet 0)?

    conf of the router is attached - hope that's not too...

    Thanks & cordially

    Thomas,

    Can't wait to show something that might be there, but I don't see here. You do not have the card encryption applied to one of the interfaces, perhaps it was not copied. Assuming your description you do it, or should it be, applied to the fa0 and you are connected. Try how you ping? Since the router or a device located on E0? If you ping the router, you will need to do an extended ping of E0 to the ip address of the client has been assigned. If your just ping the router without the extension, you will get sales and decrypts that you declare on the client. Have you tried to ping from the client to interface E0? Your default route on the router is pointing to fa0? You have a next hop to affect? You have several NIC on the client pc? Turn off your other network cards to check that you don't have a problem with routing on the client if you have more than one.

  • No "ip Routing" command on the switch and still intervlan routing.

    Hello

    In my companies 4500 switch I see there is intervlan routing configured for 4 VLANS there but I don't see any command "ip Routing" on this subject

    to enable routing on the switch. A switch can route the same if the command is not there?

  • Problem of layer 3 of SGE2010 with installing intervlan routing

    I'm new to the switches for small businesses and could use assistance in the configuration of routing for intervlan between several VLANs on the switch. I changed the 3 layer mode and configure the VLAN. When I enter an IP address for VLAN2, I disconnect (VLAN1 ip) configuration on the switch interface and I can't access the switch unless I reset it. I tried several times and each time it has the same. Is there something else I need installation before you configure the ip address for other VLANs?

    Hi Jacqueline,.

    Thank you for your participation in the community of support to small businesses. My name is Nico Muselle of Cisco Sofia HWC.

    This is the normal way for the switch to behave. There are 2 ways to work around this problem.

    1. You assign a port to the VLAN2. After the configuration of the IP address, you connect your PC to this port and make sure that it is in the same subnet as the address IP 2 VLAN.
    2. You assign a static IP address for the vlan by default first and make sure your connected PC is in the same subnet.

    The reason for this behavior is that the switch has its DHCP client enabled, if no DHCP server is available, it will return to its default IP 192.168.1.254 (which I assume that you connect to the configuration).

    However, once you set up a static IP address on the switch, the DHCP client and the default IP address is disabled, which means that the obtained from DHCP or the default IP address 192.168.1.254 are more accessible.

    I would go to step 2, because it's the simplest solution to your problem and you would like a default static IP VLAN in any case, I guess.

    I hope this helps!

    Best regards

    The printer detects the wireless (2. 4 g) network, but can't coplete the connection. Tried the two direct input the network key and using WMA.

    -The display panel shows "wireless invalid password (WPA) is entered.

    -The results of network printer test page indicates a FAILURE on safety.

    I was able to connect to multiple other devices (laptop, iphone, Kindle...) without any problem. Used the two direct entry of the key network and WMA.

    Anything else I can try?

    Find a new update of the firmware for the printer (May 9, 2016).

  • Satellite A100-014: connection Wireless D-link router problem

    I think that it is working properly. I keep getting kicked from WLAN (connected to the dlink DWL 900AP), but if I plug the Ethernet cable it works very well.

    This vista software is a major pain. It will let me install the d-link software.

    Does anyone have any knowledge about it?

    If you need the d-link software you must ask the manufacturing of router for these updates or visit the support site for manufacturing.

    What WLan encryption are you using? I used WPA2 and I had similar problems.
    My router and the wireless network card were not 100% compatible with this encryption.

    Now I use the WPA or WEP and it works.

  • Time Capsule router problems

    Recently, my wireless network has had problems.  He became more and more slow.  My devices connect without problems and the signal is full but it takes significantly more time to do something about it.  My iMac doesn't seem to have problems but are my other devices (phone, Tablet, PS3, PS4).  Netflix is essentially very bad because it keeps buffering every 30 seconds and I have to run PS4 upgrades must run all night because they take 8 + hours to download.  I had questions about 5-6 months, which I was able to correct by closing all the way down, 20 minute wait and then turn the modem, the router, and then the computer.  I tried again twice, but he don't seem to have any effect.

    My modem is a Motorola Surfboard SB6141.

    My router is a time capsule, model A1409.

    iMac is a model 27 inch late 2009 10.10.5 running.

    The capsule is connected directly to the modem via Ethernet.  All other devices are connected to the wireless network.  Any advice would be greatly appreciated.

    Thank you!

    Something directly connect to the modem by ethernet. And do a test to see if download and shipping limits are together and working properly.

    You must turn off the modem at each change of customer... 5 minutes is probably enough, but this can take up to 15 minutes.

    If you have good speed then when you put the back... TC test via ethernet to TB... once again, you should get almost the same download and upload speeds as the test to the direct modem.

    Now, test your wireless... you say that the iMac has no problem... so please give us the numbers... It is difficult to work from vague descriptions...

    Then, I need to know the connection speeds and all possible information. Run diagnostics on the computer wireless.

    You should also do a factory reset full of the TC and reconfigure it as follows.

    Start from a factory reset. No files are lost on the drive hard in doing so.

    Universal factory reset

    Turning off the TC... That is, remove the power supply cord or the power at the wall outlet, wait 10 seconds... Hold the reset button... be nice... Turn on always even now in reset... and keep holding in for another 10 seconds. You may need assistance because it is difficult to hold in reset and power on. It will show the success quickly flashing led front. Release reset... and wait a few minutes for the TC to reset and return with the factory settings. If the front LED flashes quickly you missed and simply try again. The reset is quite fragile in these... Press the key while it is just click away and not more... I've seen people bend lever or even break. I use a toothpick as a tool.

    NB. None of your files on the hard drive of the TC are removed... This simply clears the settings of the router of the TC.

    The installer the TC.

    And then redo the configuration of the computer with the Mavericks - Yosemite - ElCapo. (MYELCAP)

    1. the use of very short names... NO APPLE RECOMMENDED names. Without the space and pure alphanumeric characters.

    for example TCgen5 for the base station and the name of the TCwifi wireless.

    If the problem is using wireless TC24ghz and TC5ghz with fixed channels as it also seems to help stop the nonsense. But it can be tried in the second round. IE, plan on a first and second series of changes to fix this... If all goes well... I note other steps can you tour2.

    2. use all passwords also consistent with 1. but maybe a little longer. IE 8 and 20 characters of mixed cases and numbers... no alphanumeric non-caracteres.

    3. If the TC is router, you can ignore this point. It is only a problem when the TC is bridged.

    If ensure that the TC is always the same IP address... you will need to do this on the main router using a dhcp reservation... or a bit more complex setup by using the static IP address in the TC. But it's important for deriving from intellectual property in all directions when MYELCAP do not remember his name for 5 min after a reboot done for poor network management.

    4. check that your share on the computer name does not change... Make sure that it is also in line with the above... short without space and pure alphanumeric... but this change will mess up your TM backup... so be prepared to make a new, full backup. Sorry... keep this one for the second round, if you want to avoid a new backup.

    5 attach the TC disc into the computer manually.

    In Finder, go, connect to the server in the main menu,

    Type in SMB://192.168.0.254 (or whatever ip of TC is that you made static. It's a default router 10.0.1.1 and I encourage people to stick with it unless you know what you're doing).

    You can use the name... SMB://TCgen5.local where you replace TCgen5 with your name of TC... local is the default domain of the TC and does not change.

    However the names are not so easy as... the IP address nor reliable. They are not at least not in Yosemite. The field can also be a problem if you are not clogged or wireless directly to the Treasury Board.

    6. ensure that IPv6 is set to link-local only in the computer. For example wireless open network, wireless and Advanced preferences / TCP/IP... and the difficulty of IPv6. link-local only. Do the same for the ethernet if you use it.

    It is a lot more jiggery pokery, you can try, but the above is a good start... If you still find not reliable... don't be surprised.

    You may need to do more work on the computer itself. for example, to reset the NVRAM/PRAM/SMC... helped some people. A clean installation of the operating system is also useful if you update installed.

I used the installation cd supplied with the router, which has not seen any problem until I removed the old router and plugged in power in the new after connecting the anc ethernet cables to my cable modem. For some reason any the software wont recognize the new router so I can continue with the configuration of the installation. Since I plugged the new router in the same connections that I had had the old LInksys router connected to, I do not understand why and I can not proceed with the installation. I finally just reinstalled... connected., my old router and it works fine, but this isn't a solution for me.

    It might have something to do with the sequence to connect the different cables? I also tried to use 192.168.1.1. via my browser and could up the installation screens but it wont let me install the new router so that the old one is still in place and without the old one in place, I can not access the configuration on my desktop screens.

    I have my router in a closet with my... cable modem... .but the WRT54G worked fine for 2 years in the same cupboard and I also installed a Netgear N600 router as an alternative. is it installed fine until what happened to the point where he said the beach was too limited. .i guess work in the closet.  I guess I can buy a range extender to solve this problem, but I have no experience with those so im not sure if this will solve the problem. I prefer to get the Linksys WRT310N to work if possible.

    Thanks for any help you can provide.

    Thanks for the tips on how to handle this. Fortunately, I discovered later that the Linksys router, I bought on ebay, is apparently defective and it now resides in my trash. That said, I also realized with the help of a neighbor that my Kindle works with the good old Linksys router I used for 4 years or more. My problem was to not understand how to download books on the Kindle, even though I thought I did. So the problem is moot. Sorry I got worth this site with no problem.

  • Connectivity of the wireless router problem

    I have a Cisco's Linksys WRT160N wireless router.  After it is up and running, all my wireless devices work fine.  My sons Wii for my laptop, my wifes iPod Touch. But the strangest thing is happening.  I have problems connecting to the internet with my desktop computer that is hard wired to the linksys router.

    Often I can connect any... other times it's quite slow compared to when I plug my office directly to a cable modem.  Finally, sometimes certain aspects of the Web page will appear while others won't.

    Question: Is damaged?  Or is there something that I am missing.  You would think it would be right forweard enough... OH, I have also replaced the cables from the desktop to the router and have already done all the reboot that I care to do as well as redo the ip address in the part of the repair of my control panel.

    Any ideas?

    Access the Page of configuration of your router and lower the MTU size of the router to Auto/1500 to 1400.

  • Interference WRT400N Wireless Router problem.

    Hello!  I would be grateful if someone can help me with my problem.  I live a mile on a mountain.  When a vehicle comes to the top of the mountain at a certain point, we get interference which causes the computer programs and the internet to freeze until the vehicle pass at some point.  Simply, this started about 6 months ago and is very frustrating.  How can I change the frequency channel on the Linksys simultaneous Dual - Band Wireless - N Router, model #WRT400N?

    On the wireless page, you have not selected Manuel as you're supposed too?
