Displaying BGP4+ information
9
This display shows the following information.
For example, to display details about all RIB routes for neighbor 2001:db8:2000:4::110, enter the
following command at any level of the CLI.
TABLE 17 Summary of RIB route information for a BGP4+ neighbor
This field... Displays...
Number of RIB_out routes for a
specified neighbor (appears
only in display for all RIB routes) The number of RIB routes displayed by the command.
Status codes A list of the characters the display uses to indicate the route’s status. The
status code appears in the Status column of the display. The status codes are
described in the command’s output.
Prefix The RIB route’s prefix.
Next Hop The next-hop router for reaching the route from the Virtual ADX device.
Metric The value of the advertised route’s MED attribute. If the route does not have a
metric, this field is blank.
LocPrf The degree of preference for the 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 can have a
value from 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 RIB 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.
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.
