Displaying BGP4 information
27
This display shows the following information.
TABLE 143 BGP4 route-attribute entries information
This field... Displays...
Total number of BGP Attribute Entries The number of routes contained in this router’s BGP4 route table.
Next Hop The IP address of the next hop router 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 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.
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 router 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
NOTE: Information loss under these circumstances is a normal part of
BGP4 and does not indicate an error.
Local Pref The degree of preference for routes that use this set of attributes
relative to other routes in the local AS.
