I've setup a Catalyst 3750 to L3 route and interface directly with an MPLS network via its int g1/0/24 and g2/0/24. This Cat3750 runs BGP on it to BGP peer with the MPLS cloud. Attached is the configuration I've done.
NO problem with running the switch until I carry out a link fail-over test by pulling the cable off int g1/0/24 (primary link) and at the same time do a continous ping to a remote site from a PC on the local LAN (and console to the switch at the same time). From console I can see that it took < 10 sec for BGP to converge and I was able to ping (from the switch) to the remote site. The PC however, timed out with several ping failures and was not restored shortly after 70 seconds. What I don't understand is why does it takes 70 seconds for the PC to reach the remote site instead of 10 seconds. I have a feeling that this might have something to do with the command "bpg dampening" but just want to have a second opinion out there. Thanks in advance for your comments.
