Displaying BGP4 route-attribute entries
The route-attribute entries table lists the sets of BGP4 attributes stored in the router’s memory.
Each set of attributes is unique and can be associated with one or more routes. In fact, the router
typically has fewer route attribute entries than routes.
To display the IP route table, enter the following command.
BigIron RX# show ip bgp attribute-entries
Syntax: show ip bgp attribute-entries
Here is an example of 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 this set of attributes came to BGP through
EGP.
• IGP – The routes with this set of attributes came to BGP through
IGP.
• INCOMPLETE – The routes came from an origin other than one of
the above. For example, they may have been redistributed from
OSPF or RIP.
When BGP4 compares multiple routes to a destination to select the best
route, IGP is preferred over EGP and both are preferred over
INCOMPLETE.
Weight The value that this router associates with routes from a specific
neighbor. For example, if the router receives routes to the same
destination from two BGP4 neighbors, the router 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 router that originated this aggregator.
Aggregation AS The AS in which the network information was aggregated. This value
applies only to aggregated routes and is otherwise 0.
Originator The originator of the route in a route reflector environment.
Cluster List The route-reflector clusters through which this route has passed.
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.
