Exclude the network using BGP network command

Hello:

I am using BGP and I do redistribution of OSPF into BGP while I read the best way to do it is to use the network command.

Now, I do the redistribution of OSPF in BGP using a list of prefixes that specifies the network to redistribute.

Is possible to do so by the order of network?

My network to redistribute is the 8.0.0.0 / 8 but the 8.0.0.0 / 16 is excluded.

The IGP network is with specific directions of IP, so I think I also use the Auto-resume option or set the order of the aggregate-address.

Another option that I prefer is to advertise the network into parts because some routers of entry to ACE are better for the first part of the network and the other are better in the second part. So I intend to announce that this networks.

  • 8.0.0.0 / 9 (excluding 8.0.0.0 / 16)
  • 8.128.0.0 / 9

Thank you very much for your help. In this case, Juan.

Hi you

By default, network control announce only mask what u applied and it should be existed in the routing table.

Another option, you can use the roadmap as well with the network command

  • Cannot use the network after the first time backup volume machine

    Hello

    After the update to OS 10.11.4 my MACs are unable to use the network backup volume more.

    The volume of time machine is a device (RAID of LCM InXtron Taurus-S) external USB connected to a server of iMac (also running OS 10.11.4). Four MACs use this device as a backup time volume machine (all systems 10.11.4).

    What I've done so far has been clear the volume (twice) and rename with different names than in the past. Than I started the new backups for all of my MACs. The fist backup works fine for all machines. After it says, that the first backup is over, and he tries to perform the second backup an hour later, it is said that the volume does not support the necessary functions of AFP.

    I am still able to connect to the volume via afp: / /... If the finder (go to). As long as I use the volume for a single machine works. If I announce a backup from another machine, it evokes this error.

    Any suggestions?

    I can't connect to the internet using my wireless network connection. I had made the diagnosis and he stated that "the DHCP is not enabled for the wireless network connection. I had checked the DHCP, but it has been activated!... Someone would give any suggestion for me to solve the problem?

    Open the run command box by pressing Windows key + R, type services.msc and press enter . Search The Client DHCP and check if it is enabled or disabled. If disabled then turn it on and see if the problem still persists or not.

    Open the run command box by pressing Windows key + R, type cmd , and press enter . At the command prompt, type ipconfig/all and press ENTER. Now, check the IP address, default gateway, DNS etc. If you find all the information is correct, but you cannot yet access the Internet so if you connect the wireless network is secure or not. To determine the glance to the wireless network icon in the taskbar, then click on it. It will show you the available wireless networks. If there is a "yellow shield" present on the network icon, the network is not guaranteed, if there is no "yellow shield" does while the network is secure. In a secure network, you might have a "network security key. In this case try to disable the 'Network security key' option for this network. To do this:

    Open Control Panel , click network and Internet , click network and sharing Center , click manage wireless networks on the left.

    In the list select the wireless network and do a right click, select Properties, Security disable tab all options that is, in security type do not select no authentication (Open) and to the type of encryption , select none .

  • I am unable to connect with GANYMEDE + connection after the addition of aaa authorization network command

    Hello

    I test an aaa authentication switch when it does not communicate to ISE, and I found a strange behaviour. After that I added the aaa accounting and authorization authentication controls and reloaded the switch I was not able to connect to the switch with the GANYMEDE login

    The switch continued in cycles showing the banner give 3 times authentication failure message and then the cycle begins with the failed, banner and sign message

    I removed the aaa authorization network command and I reloaded the switch and I was able to connect successfully.

    could someone help me with this problem.

    Hi Nitesh-

    This command (... aaa authorization network) has nothing to do with the admin authorization on the n basis (in this case, the switch). This command applies to the network connections such as PPP, SLIP, etc.

    In addition, aaa authorization can be performed by Ray and not only GANYMEDE +. RADIUS is not too powerful and you can provide authorization command sets but you can always return roles and different levels of privilege.

    Have you tested the above configuration syntax? I did and it works as expected!

    Thank you for evaluating useful messages!

  • Integrate the new routers BGP network Nexus 5 K

    Hello

    I'm having a little trouble wrapping my head around how to do it.  We have an existing network that consists of Nexus 5 K in the data center.  We are now trying to design and implement a new site in the new network.

    I have attached a diagram of the network in question segment.

    To simplify the management of roads, we want to integrate the new routers in BGP network (both routers 2900 are new).  What I'm having lot to grasp, is how to intigrate the new existing network from the network.

    In a lab, I am only able to implement the VRF, BGP using RD & RT scenario.  From my understanding and correct me if I'm wrong, if I use RD and RT. on the 2900 s I would need the same configuration on the Nexus for traffic.  Under normal circumstances I might just add RDs and RTs to the N5K but then I also need to go to all other locations and configure them as well.

    I would be grateful for comments on how I can integrate these new routers with the existing network and maintain routing Dynamics using BGP.

    Thank you

    If all inter the VRF routing is handled by the firewall, then your installation program can be quite simple.  You probably don't want BGP/MPLS on the dark - fiber link

    lets say it was a vlan per VRF.

    (1) If you can import/export routes on the 2911 on the main site of each VRF see other VRF routes. If you want to only route through the firewall there is not need to do. In fact, as far as I can see that you want to import and export routes, you simply use subinterfaces on the firewall to control the flow of traffic.

    The way to completely isolate the traffic is-

    (1) extend the VRF all the way from the main site to the remote site. Do you this by creating some subinterfaces on dark fiber between the 2900 connections s and then place each subinterface in the corresponding VRF.

    (2) on each LAN interface facing the 2900 s you again create the same subinterfaces and assign in the corresponding VRF.

    (3) to each LAN interface run you a trunk to the switch. (Not sure what you have on the remote site). In the primary site of this trunk would go to the Nexus switch and there would then be a trunk of the Nexus switch to the firewall. If it were a vlan by VRF there was no need of lass on the Nexus switch.

    By VRF you can then run a protocol for routing if necessary for example. EIGRP or OSPF.

    With the above, the only way for any device in a particular VRF to communicate with any other device is via a firewall interface. There is no import and export from any road. Are not in the VRF subinterfaces on the firewall and the firewall has a global routing table that contains all the routes each VRF and you strictly control access with a stateful filtering.

    If you could not use subinterfaces on dark fiber connections, you can always watch GRE tunnnels.

    The foregoing assumes that it is a vlan per VRF. If several VLANs, so there is a need of lass on the Nexus if routing between VLANS in the same VRF could be done. It is the same on a remote site.

    If you do not run BGP to import and export on the 2900 s then you then trade routes between VRF. If the default gateway of customers has been set on the firewall then you should always get separation but if the customer has changed the door of the subinterface 2900 for example then this device would have within each VRF to VRF other routes.

    So, based on what you described I do not see the need for any import/export routes.

    Does make sense?

  • Shared folder on the network publicly without using homegroup

    I try to share a folder on my network so that anyone can access and modify files in this folder. But I also have other actions, that they do not have access to the. Homegroup is not a viable alternative. The only solution I've seen in the past is to create a connection on my PC to allow users to open a session, however, allowing them to open a session locally is not an option either.

    Any suggestions?

    Hi Dave7

    You can try the following to see that you can allow users to access the share using anonymous authentication:

    1. Right-click on the folder you want to share, on the sharing tab note the network path
    2. Now go to start and find "Local security policy" and press on enter
    3. "Local policies", then click on Security Options
    4. Find the policy: "network access: Everyone permissions apply to anonymous users" and set the setting to "Enabled" and click OK
    5. Now find the policy: "network access: shares that can be accessed anonymously ', enter the network path you noted in step 1 in the text box, and then click OK
    6. Now open command prompt, you can search for cmd in start search and press enter
    7. Type the following command and press ENTER: gpupdate/force
    8. Now you should be able to access the share without the need to enter credentials, but if they try to access on the other hand they will be invited with the connection dialog box

    If please test and let me know if it works, or if you have any problems, as I suppose you are a local administrator on the computer.

    Please note that this will reduce security and can open an entry point that could easily be exploited, as anyone on the internet can potentially access share and emptying of viruses and trojans on it.

    Thank you

    But once that I kept my system with external IP address (excluding local network of my company), oracle gives these following errors when tomcat start

    Here is the following URL will display the error during the startup of tomcat.

    The network adapter could not establish the connection,

    In these two files, listener and tnsnames ora ora, need to change the configurations if I change the Ip address of the system?

    even I tried my address keeping external Ip instead if host in these two configuration files, yet this does not work.

    any help would be greatly appreciated!

    Thank you.

    Because as I explained - your listener is listening on localhost only. localhost is never accessible to another machine.

    Stop your listener, change the listener.ora to listen to on the real machine name and start the receiver.

    In addition, your tnsnames.ora points to localhost...

    Stop using localhost, unless you only want things to work on the same machine.

  • How to - migrate VM through the vCenters using PowerCLI - bypass the validation of network

    Hello

    I'm working on an automation project, which requires that we have a VM of 1 vCenter to another.
    Each vCenter is a stand-alone instance, they are not related.

    The problem we have is that cmdlets Import-vAPP and export-VAPP are 'too' data validation.

    VAPP export works very well, however, our problems are on the part of import-vapp.

    Each vCenter uses a distributed switch, so when we run this command, we get the below error

    Import-vApp -VMHost $targetEsxhost -Source $importpath -Name $hostname -Datastore $targetDatastore -Location $targetCluster -DiskStorageFormat "THICK" -Force -ErrorAction Stop
    

    Import-TIME: 28/03/2016-09:18:29 Import-TIME host lacked any defined virtual network.

    Online: 8 char: 1

    I'm guessing that the import fails because the switches names and IDs are different on the target as on the source vCenter vCenter

    We use vCenter 5.1 and 5.5 PowerCLI for execution of our automation tools.

    What other options do I import to be successful, somehow bypassing validation of network?

    We can reconfigure our VM subsequently, but we want to just that import of fill.

    Is there any other cmdlets, that we can use, or go on the road to the API and something like Onyx allows you to spy on the vSphere Client to "make our own import-function"?

    All I know, you cannot ignore the validation, but you might take away the network.

    What I mean, check out the network configuration and store it outdoors, then try to remove the adapters for virtual machines.

    Now you should be able to migrate the virtual computer.

    During the migration, restore the vNIC and from the saved data, you have the network configuration.

  • Is it possible to debug an iOS device via a USB rather than using the network?

    Hello

    Is it possible to debug an iOS device via USB instead of using the network? I want to test demand for offline scenarios. Please let me know.

    Thanks in advance,

    Swathi.

    Router is on but disconnected from the internet. Your computer is assigned an ip address by the router. It will be something like 192.168.0.1 the IOS device can be 192.168.02. Most of the routers will identify attached devices and their IP via the administration panel. If you receive a Windows command prompt and type ipconfig, you will see the IP address of the PC.

    Your router is now a LAN - is differrent from being connected to the internet.

  • Use the second router to extend the network to Time Capsule

    I have a v7.6.7 running Time Capsule 1 TB and older airport. I'm hoping to add a second router in a new location, and I use an ethernet cable from the TC at the new router (TP Link Archer C5), updated to the latest version of the firmware. The IP address of the TC is 192.168.1.1.

    I have set up my router C5 as follows: allocation of IP 192.168.1.199, value DHCP = off, and I connect a cable between the TC ports and port WAN (not Internet) available on the C5. In the C5 wireless settings, I tried both using the TC SSID and pw and creating a new SSID and pw. In both cases, the network will work for a short time, but eventually the entire network, including the TC, stops working. I made no changes to the parameters of the TC on any trial.

    Is it possible to use a TC and a router not Apple on the same network? If so, what are the right settings for the TC and the secondary router? If not, is it better to have the not Apple as main router and add the TC to the network created by the non-Apple router?

    Is it possible to use a TC and a router not Apple on the same network? If so, what are the right settings for the TC and the secondary router?

    Yes. That would be the basis of a network of mobile type.

    The key for a roaming network parameters are:

    • The 'primary' router must be configured as a router. In other words, it must have active NAT and DHCP services.
    • All other routers used in a network of roaming must be reconfigured as a bridge.
    • All routers must broadcast a Wi - Fi network that uses the same network (SSID, aka) name, and the type of wireless security, and the password.
    • All routers must be interconnected by Ethernet. To provide Powerline adapters using an Ethernet connectivity should also work.

    If not, is it better to have the not Apple as main router and add the TC to the network created by the non-Apple router?

    Should not really which is the main in the roaming network.

    I think at this point, your current circuit line. To check that, I would suggest that you consider to bring back the router C5 in the same room as you have the TC. Then connect it directly to one of the LAN of the TC ports. Complete the entire upward to a mobile network and test it. If everything works, bring back the C5 in the desired location, and then try again.

    If it fails, then the circuit line will be tested to check that it provides a solid 'Ethernet' connection between the adapters.
