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.
•
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.
•
E – EBGP. The route was learned through a switch in another AS.
•
H – HISTORY. Route dampening is configured for this route, and the
route has a history of flapping and is unreachable now.
•
I – IBGP. The route was learned through a switch in the same AS.
•
L – LOCAL. The route originated on this switch.
•
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 shown in lowercase, the software was not able to
install the route in the IPv6 route table.
•
S – SUPPRESSED. This route was suppressed during aggregation
and thus is not advertised to neighbors.
•
F – FILTERED. This route was filtered out by BGP4+ route policies
on the switch, but the switch saved updates containing the filtered
routes.
