eBGP TTL matching requirement

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) multihop EBGP = TTL = 255 (by default) - likewise, if one end sends something else, adjecancy won't come up multihop EBGP = TTL = modified hop value - ex. 15 (both ends have to have it) I understand that ttl-security and its implications. Thanks, Vitto
