TABLE 12 BGP4 route information

This field... Displays...

Total number of BGP4 Routes The 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.
