Total number of routes stored in the BGP routing table and amount
of memory consumed by routes. If several peers have advertised a
route to the same prefix, all routes are included in this count. routes
Number of routes to unique prefixes stored in the BGP routing table
and amount of memory consumed by routes. If several peers have
advertised a route to the same prefix, only the best route is included
in this count. destinations
Number of routes in the BGP routing table that have been inserted
into the IP routing table, plus prefixes for which there are currently
no routes but which have had to be withdrawn from peers to which
these prefixes may been previously advertised. routes selected for route
table installation
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. path attribute entries
Number that is increased by one each time a route in that RIB is
added, removed or modified. Local-RIB version
Number that is increased by one each time BGP updates the routes
in the IP routing table based on changes in the local RIB. The FIB
version matches the local-RIB version when BGP has finished
updating the routes in the IP route table. The FIB version is less than
the local-RIB version when BGP is still in the process of updating
the IP routing table. FIB version
