eBGP TTL matching requirement

2010-05-11 Thread Vitto Capabianco
Folks, Is there a TTL value enforcment on EBGP session establishment? For some reason I thought that both peers have to have the SAMe value? Is that true? For example: default EBGP = TTL = 1 (if one end sends something other than 1 in its OPEN message, we won't bring up the adjecancy)
