A quote from IOS manual: ------------------ A BGP routing process will verify the connection of single-hop eBGP peering session (TTL=254) to determine if the eBGP peer is directly connected to the same network segment by default. If the peer is not directly connected to same network segment, connection verification will prevent the peering session from being established. ------------------ http://cisco.biz/en/US/docs/ios/12_3t/ip_route/command/reference/ip2_n1g t.html#wp1109875 Miya -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
