Displaying BGP4+ information

For example, to display details about all routes a Virtual ADX device has advertised to neighbor
2001:db8:2000:4::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 Virtual ADX device associates with routes from a specific
neighbor. For example, if the Virtual ADX receives routes to the same
destination from two BGP4+ neighbors, the Virtual ADX 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 Virtual ADX device received better routes from other
sources (such as OSPFv3 or static IPv6 routes).

•

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

•

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

•

L – LOCAL. The route originated on this Virtual ADX device.

AS-PATH

The AS-path information for the route.
