Displaying BGP4+ information

Weight

The value that this device associates with routes from a specific neighbor. For
example, if the receives routes to the same destination from two BGP4+
neighbors, the 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 device 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 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 in the same AS.

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 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
device, but the device saved updates containing the filtered routes.
