Weight The value that this switch associates with routes from a specific neighbor. For example, if the
switch receives routes to the same destination from two BGP4+ neighbors, the switch prefers
the route from the neighbor with the larger weight.
Status 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.
•
b – NOT-INSTALLED-BEST – BGP4+ has determined that this is the optimal route to the
destination but did not install it in the IPv6 route table because the switch received
better routes from other sources (such as OSPFv3, RIPng, or static IPv6 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.
•
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.
NOTE: 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”.
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.
