BGP4 route information
Displays...
The number of BGP4 routes.
A list of the characters the display uses to indicate the route's 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.
The network prefix and mask length.
The route's status, which can be one or more of the following:
•
NOTE: B – BEST. BGP4 has determined that this is the optimal route to

The last time an update occurred.
The next-hop router for reaching the network from the device.
The IP address of the neighbor that sent this route.
The degree of preference for this route relative to other routes in the
local AS. When the BGP4 algorithm compares routes on the basis of
local preferences, the route with the higher local preference is chosen.
The preference can have a value from 0 – 4294967295.
The route's metric. If the route does not have a metric, this field is
blank.
A – AGGREGATE. The route is an aggregate route for multiple
networks.
the destination.
If the "b" is shown in 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
nonetheless 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.
was selected as one of the best ones to the destination. The
best route among the multiple paths also is marked with "B".
If the "m" is shown in 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.
