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.
device# 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.
device# show ip bgp attribute-entries
Total number of BGP Attribute Entries: 7753

TABLE 100 show ip bgp attribute-entries output descriptions
This field Displays
Total number of BGP4 Attribute Entries The number of routes contained in this BGP4 route table.
Next Hop The IP address of the next-hop device for routes that have this set of
attributes.
Metric The cost of the routes that have this set of attributes.
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 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.
Originator The originator of the route in a route reflector environment.
Cluster List The route-reflector clusters through which this set of attributes has
passed.
Aggregator Aggregator information:
• AS Number shows the AS in which the network information in
the attribute set was aggregated. This value applies only to
aggregated routes and is otherwise 0.
• Router-ID shows the device that originated this aggregator.
Atomic Whether the network information in this set of attributes has been
aggregated
and this aggregation has resulted in information loss.
• TRUE - Indicates information loss has occurred
• FALSE - Indicates no information loss has occurred
