Displaying VRF route information
The user can display information about BGP routes that are contained within a specified VRF route
table by entering a command such as the following at any level of the CLI.
Brocade# show ip bgp vrf red
Total number of BGP Routes: 285
Status codes: s suppressed, d damped, h history, * valid, > best, i internal

This display shows the following information.
TABLE 121 BGP4 summary information
This field... Displays...
Total number of BGP Routes: The number of BGP routes.
Status or Status Codes The route’s 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: When 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 due to the rib-route-limit (or RTM route
table size limit) and always-propagate option to allow the propagating
those best BGP 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 Brocade 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: When 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.
NOTE: This field appears only when the user enters the route option.
