Frequent BGP flaps on Cisco 7200 with IOS 12.4(24)T7

[umakanthreddy]

i am having issues with frequent bgp flaps on the Cisco 7200 series router from past 1 week. I have raised a ticket with ISP but couldn't get any resolution

from them as the flap is for about 2min.

When ever we see BGP flap, we are not able to ping the remote end IP, Also at that point we drops on the interface connected to ISP.

Can anybody please let me know why this flaps are happening which would be of great help for me.

Thanks in Advance.

First off, the IP connectivity only is not clean here, did you try showing the ping loss to provider?

Have you checked the physical interface connecting to provider, are they recording any drops?

can you paste 'sho ip bgp nei | i Last'

Also do check the 'sho proc cpu hist' and match the timestamps with the BGP adjacency change to rule out CPU on your box.
