Hi, Douglas,
Did you use “neighbor ttl-security” on both site of the neighborhood? or use “neighbor ttl-security” on one site and use “neighbor ebgp-multihop” on another site?
You have to use “neighbor ttl-security hop” in the peer sessions of each nodes.
The two commands are different on the inital TTL value on the message. The drop-off TTL threshold are different too. For example, “neighbor ebgp-multihost 4″ set intial value TTL=4 on the peer message and drop off the peer message if TTL = 0.
“neighbor ttl-threshold hop 4″ uses default TTL=255 on the outgoing peer message and drops off the ingress message if it’s TTL = 251.
