Monitoring BGP Routes with Nonnatural Network Masks
Purpose Display information about routes that have nonnatural network masks. Report whether
the indirect next hop of a route is unreachable; if not, display the IGP cost to the indirect
next hop.
Action To display information about routes that have nonnatural network masks:
host1# show ip bgp cidr-only
Local BGP identifier 111.111.111.111, local AS 444
0 routes (0 bytes used), 0 distinct destinations (0 bytes used)
0 routes selected for route table installation
0 path attribute entries (0 bytes used)
Status codes: > best, * invalid, s suppressed, d dampened, r rejected

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.
If several peers have advertised a route to the same prefix, only the
best route is included in this count. distinct destinations
Number of routes in the BGP routing table that have been inserted
into the IP routing table 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
