RIPv2 / routing domain
Hello
I found there is a field in the header of RIPv2 which is: routing domain.
It seems to be like a process id (as vlan id) so that routers have not the same routing domain will not process packets of RIPv2.
1. am I right?
2. how to change the value of this field?
Thank you
Hello
I think that I now know more about the "routing domain".
First of all, RIPv2 has been codified in 1388 RFC. Indeed, this RFC defined a field routing domain inside the RIP message header. The routing domain has been defined as follows (RFC 1388 Section 3.2):
The Routing Domain (RD) number is the number of the routing process to which this update belongs. This field is used to associate the routing update to a specific routing process on the receiving router. The RD is needed to allow multiple, independent RIP "clouds" to co- exist on the same physical wire. This gives administrators the ability to run multiple, possibly parallel, instances of RIP in order to implement simple policy. This means that a router operating within one routing domain, or a set of routing domains, should ignore RIP packets which belong to another routing domain. RD 0 is the default routing domain.
However, in the RFC 1721 "RIP Version 2 Protocol Analysis", article 2 stipulates:
The significant change from RFC 1388 is the removal of the domain field. There was no clear agreement as to how the field would be used, so it was determined to leave the field reserved for future expansion.
Accordingly, the RFC RIPv2 updates, namely the current 2453 RFC and RFC 1723 removed the routing domain label and instead treat the must-be-zero field, or else not obliterated. Your Wireshark obviously believes that the RFC 1388 RIPv2 is running and try to interpret a field not used in the header of RIPv2.
I discovered later that this behavior in Wireshark can be configured: choose Edit-> preferences, and then click protocols, find the RIP, and there you will see a box saying 'field display routing domain '. Uncheck the box.

PIX &; tagged RIPv2 routes
Hello!
I noticed that the PIX cannot use RIPv2 routing updates which have marked lines (zero tag). These routing updates, I got this error message:
107002: pkt RIP was due by 10.1.20.1: version = 2 on the interface outside
What is the function or the bug?
Hello
You are on the money. The PIX does not install RIP v2 with set of routes. This is by design, but is probably something we could change quite easily (the FWSM currently accepts these roads). My guess is that no one has ever asked before. If it's something you want to see added, contact the local Cisco account team and see about getting a high to this improved feature. Sorry for the news, but I hope that this helps to answer your question.

Mike,
(Hopefully) answer both of your questions.
You can have different trustpoints with the same certificate of the issuer, no need to use two different cases.
I actually wasn't 100% corrent in my previous intervention, trustpoints will also have associated reversal/shadow certs, so strictly speaking more than two.
IRT. IKEv1 and identity, we have limited options.
(1) auto (pick up method according to the type of connection)
(2) address - provide the IP address associated with a card crypto instsance (i.e. the source of the cryptographic packages).
(3) Hostname - hostname configured on the box. (FQDN)
(4) DN - chosen DN of the certificate
In addition, you can configure user-name of full domain as identity.
As far as IKE goes, you can have as many certificates as you want of cases as much as you want (in MM3 and MM4 both sides of the negotion will agree on the use of certificates to authenticate to each other).

Wireless router requesting domain username, password and logon
I recently bought a router without wire - WBR - T2 - as my old netgear router has stopped working. I can connect via the ethernet fine connection and access the internet. But on my computer Vista laptop when I try to connect to the wireless network, what I asks me to enter a username, password and domain logon. The old netgear router has not asked for these. Any help if her I need information would be appreciated.
Thank youJonI don't know where you get the application for the user name, etc. Your computer is on a domain? In the meantime, here is general information about the implementation of a wireless network. See if anything here helps you.
To configure the router:
Have a computer connected to the router with an ethernet cable. Examples given are for a Linksys router. See the manual of your router or the router mftr's Web site. for the parameters by default if you don't have a Linksys. Open a browser such as Internet Explorer or Firefox and in the address bar type:
http://192.168.1.1 [Enter] (it is default IP address of the router, which varies from router to router then check your manual)
This will bring you to the login screen of the router. The default username is blank and the Linksys default password is "admin" without the quotes. Enter this information. You are now in the configuration of the router utility. Your configuration utility may be slightly different from mine. The first thing to do is to change the default password because * all * known default passwords for different routers.
Click the Administration link at the top of the page. Enter your new password. MAKE A NOTE SOMEWHERE THAT YOU WILL NOT LOSE. Re-enter the password to confirm it, and then click Save settings at the bottom of the page. The router will reboot and show you the box of connection again. Do not fill in the user name and put it in your new password to enter the configuration utility.
Now, click on the link wireless at the top of the page. Change the network name (SSID) wireless by default to something, you'll recognize. I suggest that my clients not use their surname as the SSID. For example, you might want to name your network wireless network "CastleAnthrax" or similar. ;-)
Click on save settings and when you get the prompt that your changes were successful, click the wireless security link which is just beside the Basic Wireless Settings link (where you changed your SSID). Most computers purchased during the last 4 years have the wireless hardware that will support WPA2-Personal (also known as WPA2-PSK). This is the desired encryption level. If your wireless hardware is older, use WPA. Don't use WEP, because who is easily broken within minutes. So go ahead and set the Security Mode WPA2-Personal. Do this and enter a password. For example, you could use the password ' here be dragons, beware you scurvy dogs! The password is what you enter on all computers that are allowed to connect to the wireless network. MAKE A NOTE SOMEWHERE THAT YOU WILL NOT LOSE.
At this point, your router is set up and if the computer that you use to configure the router will normally connect wireless, disconnect the ethernet cable and wireless of the computer should see your new network. Enter the password that you have created (exactly as you wrote it with all capital letters and punctuation) to join the network and start surfing.

Hello world
I have an FQDN object on our firewall, IP address of this Exchange every day so the firewall has a rule to allow access to it on a specified port number.
Example:
allowed to Access-list inside_access_in line 284 extended tcp host 192.168.0.25 eq 191.235.193.75 (database.windows.net) 1433 (hitcnt = 0) 0xeef0bf01
It works very well, however I can not route traffic to the firewall of our series 6500 CORE switches if I do not know the IP address of the object. I have a server that needs access to this purpose to FULL domain name.
How to get traffic from our base at the firewall?
CORE Cisco 6509 (s2t54-ipservicesk9-mz. Spa.150 - 1.SY2.bin)
Firewall Cisco ASA 5540 v9.1 21 (5)
If the IP address changes every day, so it seems that the use policy routing based on traffic for TCP 1433 forward could be the solution for you.

In VI3, I used to change the settings of the host DNS (host and domain name) to the tab 'DNS and routing' - & gt; "Identification of home." Even more, if the DNS and DHCP are configured correctly in the environment, there is no need to set these values manually - they were discovered automatically. The story is defferent in vSphere 4. I still have the set of fields 'Name' by 'localhost' and 'Domain' field is empty. And I can't change them - they are grey.
Seems that the host is still able to discover its hostname automatically. I see the proper name in the (left pane of vSphere Client) console tree. But these values are not met the 'DNS and routing' tab and I can't put them manually.
This is normal and how do I use these fields now?
Yes, you're right. It's a little strange, but it works this way in vSphere now.

I just bought a refurbished Airport Extreme and I intend to use it as my router & combine with our old time Capsule of existing one to create a roaming Wifi network.
The new Airport Extreme (renovated) is in my studio/Office - directly connected to our internet broadband wireless (WAN port)
Our small ethernet is connected to my iMac [mid 2010 running OSX 10.11.5] & a PC and extends up to 2 other domains through an ethernet switch.
This configuration works very well, our internet speed has improved slightly - better than our old T-Link router bit. WiFi available throughout the House - better on one side.
Time Capsule (2 TB) is connected by ethernet on the far side of the House, offer backup Time Machine and strong Wifi to this area.
This time Capsule was an existing installation that went perfectly with the T-Link before I bought the Airport Extreme.
I used the Airport utility to set everything up and it seems to work.
The problem is:
Combines the Capsule and extreme connected & active, the Internet gradually slows down and grinds to stop. -Wifi seems to follow suit, but is much more gradual.
If I disable the Time Capsule, the internet connection is back to normal, Airport Extreme Wifi signal is strong and extends to almost all areas.
I got to the departure of the two units configuration problems, so I reset both factory default and from that moment managed to do all this work - with the exception that the internet connection slows down. Whenever I visit a different web site, it takes more time to load/link upward.
I spoke with our ISP, the link to our tower is solid. The technology suggested that I put Wifi on each unit to use a different channel (2 frequencies & several channels each available).
So far, this has not resolved the problem, I will continue to make adjustments.
I googled this - most of the answers are not to date - usually 2012, 13, 14. and not directly related to my situation. But I will continue my search.
I'd appreciate if anyone here has any suggestions

What is the number and the model of the modem or modem/router that your ISP has provided you?
Should we assume that you use a Mac with the help of a current or recent operating system?
If you get out of the Capsule of time and leaves disabled for now, the network AirPort Extreme continue to run at full speed for a few hours and not slow down?
We ask these questions because we must first confirm that the AirPort Extreme works properly until we can begin to troubleshoot the connection to Time Capsule.

Tecra A9: Cannot join a domain or view Web sites wireless - Vista
I'm having a problem with the network card wireless on this new installation of Vista.
I can discover & connect to a wireless router, no problem, but when I try to join a domain or view most web pages does not have only ball.
I can ping local and external addresses and web pages works without any problem at all.
I tried to update the drivers from the website of toshiba wireless and when that has not made a difference on the site of intel, but nothing helped.If I plug in a network cable, everything works fine.
I have a laptop running XP that connects to the same wireless router and has none of these problems.
Help!
StuSeems that there is nothing wrong with your all wireless lan device. I think that there are some Vista settings, preventing certain pages internet working, perhaps built in the anti-virus program or firewall. Internet Explorer 7 has built in functions of security as well, so you can take a look at this.
Perhaps the first thing you could try is to use another browser, like firefox and check the settings of the firewall.

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.

Sorry for the long title: p
I recently picked up a non-profit operations in the city with offices in three locations in the city.
We have a network domain server and exchange server at the main office where I work, and the computers in the other two offices are on the field.
(I guess that VPN configurations in our routers keep everything connected, but maybe I'm wrong on this issue..)
My problem is that when the internet at the office of the admin (where the servers are) breaks down, desktop to other locations have DNS problems and cannot connect to internet... and personal devices connected to WiFi that I provide to these places are struggling as well, being able to access only certain sites and sometimes no access at all.
I think many computers to assign IP addresses, although I have added computers I have built and/or formatted and installed myself that work very well on the field.
Why computers to the other localities are struggling to DNS and impossible to connect to the internet when the domain server is offline? What can I do to change this? I want our employees to always have internet access if the servers log.
(Being a non-profit in this city it is the COMPUTER with most of the companies not having budget do not)
The problem was the result of a secondary DNS server is not located in the router from the same place. My computer guy said Comcast as the secondary where the main DNS (my domain controller) server is not available... problem solved :)

Hello
Good evening everyone.
I had a problem in Routing and remote access on windows 2003 server. This server is already configured as a file server, domain server, and application server. Also configured as a router (thanks to access routing & remote) to connect the three different networks with each other. If this server has three NICs installed and each separate NIC network cards represent.
three different networks are - 192.42.160.0/24, 192.42.161.0/24, 192.42.162.0/24
Three cards of the NETWORK adapter installed on the server as with the IP - next
NIC - 1 = 192.42.160.220, Sub - 255.255.255.0, gateway - No.
NIC - 2 = 192.42.161.220, Sub - 255.255.255.0, gateway - 192.161.220.112 (this ip address for internet access then 4 g router IP)
-3 = 192.42.162.220, NETWORK cards, Sub - 255.255.255.0, gateway - No.
Now the question is I can get Internet & (also scathing in router ip 192.42.161.112) one network i.e. - 192.42.161.0/24, BUT when I try to access the internet from another two network (192.42.160.0/24 & 192.42.162.0/24) I can not access and in addition can not ping to internet router ip - 192.42.161.112...
So, how do I access the internet to another two network also?
I was already the configuration of static routing for all three network but I wasn't always successful. I don't really know what exactly static routing this should be done in access routing & remote area so that all three network can reach to the internet?
Here is the result of the current track...
