Hi Raghav,

What version of code are you running? It could be CSCsI90250.

http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCsl90250

Also, I noticed that you are using ip tcp adjust-mss 1400 your IPSec
tunnels. Is this where the BGP peering is happening? Also, what MTU did you
set for the tunnel interface?
