Displaying BGP4+ information

This display shows the following information.
Displaying route flap dampening statistics for a BGP4+ neighbor
To display route flap dampening statistics for a specified BGP4+ neighbor, enter the following
command at any level of the CLI.
TABLE 12 BGP4+ neighbor route-attribute entries information
This field... Displays...
Total number of BGP Attribute
Entries The number of route attribute entries for the specified neighbor.
Next Hop The IPv6 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 BGP4+ through EGP.
•
IGP – The routes with this set of 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 OSPFv3.
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.
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
•
None – Indicates the attribute is not present.
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.
Communities The communities that routes with this set of attributes are in.
AS Path The ASs through which routes with this set of attributes have passed. The local
AS is shown in parentheses.
Address For debugging purposes only.
Hash For debugging purposes only.
Reference Counts For debugging purposes only.
