Displaying BGP4+ information

LOCAL_PREF

For information about this field, refer to

Table 102

on page 538.

MED

The value of the advertised route’s MED attribute. If the route does not
have a metric, this field is blank.

Origin

The source of the route information. The origin can be one 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.

EGP – The routes with this set of attributes came to BGP4+ through
EGP.

H – HISTORY. Route dampening is configured for this route, and the
route has a history of flapping and is unreachable now.

IGP – The routes with this set of attributes came to BGP4+ through
IGP.

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.

Weight

For information about this field, refer to

Table 102

on page 538.

AS-PATH

For information about this field, refer to

Table 102

on page 538.

Adj_RIB_out count

The number of neighbors to which the route has been or will be
advertised. This is the number of times the route has been selected as
the best route and placed in the Adj-RIB-Out (outbound queue) for a
BGP4+ neighbor.

Admin Distance

The administrative distance of the route.
