The table above describes the technogies associated with the connections to Abilene. It is constructed by creating a table of BGP peers associated with the router node. The peering data is obtained by doing the equivalent "show bgp neighor" on the router. That data contains a local interface except in cases where the peer is a multi-hop peer. The properties of the interfaces are collected by doing the equivalent of a "show interfaces". The data includes the speed and type of the interface on the abilene router. If two different peers come in through a common physical interface, then the connection is listed as shared. If two peering sessions for the same connection come in through a common logical interface and one is IPv4 and the other IPv6, they are combined into a common row of the table. If the BGP peer is also a pim neighbor, then the multicast column is set to "YES". Note that for IPv6, all multicast columns are therefore set to "NO". Note also that it is entirely possible for a BGP peer to have an IPv4 session on one logical-interface and an IPv6 session on a different logical-interface. Such sessions are listed on separate rows in the table above.
