[c-nsp] BGP over Etherchannel Issue

Does the peer come back up right away on the other link or does it remain down until you re-connect both the ports?

Subject: [c-nsp] BGP over Etherchannel Issue

Hi all,





I am having a rather unusual issue, and I have no idea on how or where to find any info about it.



Basically, a bgp session configured over an etherchannel (2x10G ports) goes down, if one cable is removed. This should not happen under normal circumstances, as the physical disconnection, should not affect the Etherchannel operation, as long as there is at least one connected port in operation.
The IP addresses are configured over a VLAN, which is then allowed on the etherchannel trunk.
When I removed one of the two fibers, the bgp session went down, and in the reset log the reason was peer closed the session, on both sides.




Any help would be appreciated.



Catalin
