bgp problems
hi Anyone can help me with the problems below : Hi, The configuration file is attached. For two days the link was down because the some problem in local line. Now it was set right. After that the bgp link came up and worked fine for 90 mins. After there is no data transfer in this link. By the same time I am able to ping 202.65.129.81 ( ip for my IRD), so I given a complaint to customercare, USA. And also I restarted IRD here. The link came up after 30 mins. Now again the link was up, but there is no active bgp connection. when I see bgp neighbors, it is showing No active TCP connections <<2501.log>> Any form of input will be greatly appreciated thanks Jason 2501.log
RE: bgp problems
You are using eBGP multihop so it's important to find out if you have a route to your provider and also if your provider has a route to you. You have a default route which points to your provider, but I would add a host based static route to your bgp neighbor. With BGP, you can have problems when you use a default route to get to your BGP connection; then when BGP comes up you learn a more specific route via BGP and all the other networks become unreachable due to a bad next hop. You also need to ensure that your provider has a route back to your serial interface. Regards, Aaron K.

RE: bgp problems
I have checked but the neighbor 202.161.130.249 is actually a host of a loopback interface having mask of 255.255.255.255 and I can't add in this mask in a static route , what should I do ? please mail me a [EMAIL PROTECTED] thanks Jason -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Aaron K.

O.T. BGP Problems in home lab [7:11041]
I keep having BGP problems in my home lab. I have mostly 2500's in my home lab and recently even upgraded to 16DRAM and 16 Flash thinking that would solve the problem. Most recently I was doing CCBootCamp's Lab-2 and a router with 16/16 has the error below, then rebooted itself. It will reboot, run a few minutes, then reboot again. This is on the router that is redistributing OSPF BGP. I keep have problems when running BGP on various routers and them rebooting. I am not running "debug" or any other processor intensive utilities. Any work-arounds or certain IOS versions to avoid?

Re: O.T. BGP Problems in home lab [7:11041]
not enough information Tim. (I find myself sitting here, wishing I were clairvoyent)... post your show version and maybe a show memory (we'll start with the first 4 lines of that), and the config that's crashing your router would be nice, too. I think I worked Lab-2 with a that same router running a compressed image and it was fine... -e- - Original Message - From: Tim Ross To: Sent: Thursday, July 05, 2001 12:48 AM Subject: O.T.

Re: O.T. BGP Problems in home lab [7:11041]
Tim, That sounds like an IOS issue. Ive had similar things happen. Try a different flavor of IOS on your 2500s. -Brad Ellis CCIE#5796 [EMAIL PROTECTED] Network Learning Inc cisco hardware: www.optsys.net ""Tim Ross"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > I keep having BGP problems in my home lab.
