â– Use to display information about routes that have nonnatural network masks.
â– Reports whether the indirect next hop of a route is unreachable; if not, displays
the IGP cost to the indirect next hop.
â– If you filter the display with field options, the usual introductory information
about BGP attributes is displayed only if you issue the intro fields option. See
show ip bgp for descriptions of the fields displayed by this keyword.
â– Field descriptions
■Local BGP identifier—BGP router ID of the local router
■routes—Total number of routes stored in the BGP routing table. If several
peers have advertised a route to the same prefix, all routes are included in
this count.
■distinct destinations—Number of routes to unique prefixes stored in the BGP
routing table. If several peers have advertised a route to the same prefix,
only the best route is included in this count.
■routes selected for route table installation—Number of routes in the BGP
routing table that have been inserted into the IP routing table
■path attribute entries—Number of distinct path attributes stored in BGP's
internal path attributes table. If BGP receives two routes for different prefixes
but with identical path attributes, BGP will create only one entry in its internal
path attribute table and share it between the two routes to conserve memory.
■Prefix—Prefix for the routing table entry
■Peer—IP address of BGP peer
■Next-hop—IP address of the next hop
■MED—Multiexit discriminator for the route
■LocPrf—Local preference for the route
■Weight—Assigned path weight
■Origin—Origin of the route
