Displaying BGP4+ information

For example, to display details about all routes a device has advertised to neighbor 2001:db8::110,
enter the following command at any level of the CLI.

This display shows the following information.

LocPrf

The degree of preference for the advertised route relative to other routes in
the local AS. When the BGP4+ algorithm compares routes on the basis of
local preferences, the route with the higher local preference is chosen. The
preference range is 0 – 4294967295.

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 advertised 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).

•

E – EBGP. The route was learned through a in another AS.

•

I – IBGP. The route was learned through a in the same AS.

•

L – LOCAL. The route originated on this device.

AS-PATH

The AS-path information for the route.
