Displays...

Total number of BGP4 Routes

Status codes

A list of the characters that indicate route status. The status code is
appears in the left column of the display, to the left of each route. The
status codes are described in the command’s output.

Prefix

The network prefix and mask length.

Status

The route status, which can be one or more of the following:

A – AGGREGATE.The route is an aggregate route for multiple
networks.

B – BEST. BGP4 has determined that this is the optimal route to the
destination.

NOTE: If the “b” is lowercase, the software was not able to install the

route in the IP route table.

b – NOT-INSTALLED-BEST. The routes received from the neighbor
are the best BGP4 routes to their destinations, but were not
installed in the IP route table because the device received better
routes from other sources (such as OSPF, RIP, or static IP routes).

C – CONFED_EBGP. The route was learned from a neighbor in the
same confederation and AS, but in a different sub-AS within the
confederation.

D – DAMPED. This route has been dampened (by the route
dampening feature), and is currently unusable.

H – HISTORY. Route dampening is configured for this route, and the
route has a history of flapping and is unreachable now.

I – INTERNAL. The route was learned through BGP4.

L – LOCAL. The route originated on this device.

M – MULTIPATH. BGP4 load sharing is enabled and this route was
selected as one of the best ones to the destination. The best route
among the multiple paths also is marked with “B”.

NOTE: If the “m” is lowercase, the software was not able to install the

route in the IP route table.

S – SUPPRESSED. This route was suppressed during aggregation
and thus is not advertised to neighbors.

Age

The last time an update occurred.
