Hi Sumanta,

What EXOS version are you running?
This can caused by a buffer issue when you have lots of iBGP peers that send updates and exceed the maximum number of routes per message.
As far as I can see that should not really impact the normal traffic.
Hardware is X770 and OS is 21.1.2.14.

There are hardly 30 BGP peers, spread cross in three VRs.

Then I suggest that you open a case for this. The issue reported should be investigated more thoroughly than what is possible on this forum.
Hi Ron

Thanks, I have also noticed the below behavior during redundancy testing.

When Switch A reboots, traffic fails over to switch B. When Switch A recovers, after the reboot, all the i-BGP sessions drop and then re-establish on Switch B, causing communication loss for 2-5 minutes. When Switch B reboots, traffic fails over to switch A. When Switch B recovers after reboot, all the i-BGP sessions on switch A drop then re-establish on Switch A.

This happens every single time.
