Displaying BGP4 route-attribute entries
The route-attribute entries table lists the sets of BGP4 attributes stored in device memory. Each set
of attributes is unique and can be associated with one or more routes. In fact, the device typically
has fewer route attribute entries than routes.
To display the IP route table, enter the following command.
Virtual ADX# show ip bgp attribute-entries
Syntax: show ip bgp attribute-entries
This example shows the information displayed by this command. A zero value indicates that the
attribute is not set.
Origin The source of the route information. The origin can be one of the
following:
•
EGP – The routes with these attributes came to BGP4 through EGP.
•
IGP – The routes with these attributes came to BGP4 through IGP.
•
INCOMPLETE – The routes came from an origin other than one of
the above. For example, they may have been redistributed from
OSPF.
When BGP4 compares multiple routes to select the best route, IGP is
preferred over EGP and both are preferred over INCOMPLETE.
Weight The value this device associates with routes from a specific neighbor. For
example, if the device receives routes to the same destination from two
BGP4 neighbors, the device prefers the route from the neighbor with the
larger weight.
Atomic Whether network information in this route has been aggregated and this
aggregation has resulted in information loss.
NOTE: Information loss under these circumstances is a normal part of
BGP4 and does not indicate an error.
Aggregation ID The device that originated this aggregation.
Aggregation AS The AS in which the network information was aggregated. This value
applies only to aggregated routes and is otherwise 0.
Learned From The IP address of the neighbor from which the device learned the route.
Admin Distance The administrative distance of the route.
Adj_RIB_out 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.
Communities The communities the route is in.
