Displaying BGP4+ information

NOTE
Portions of this display are truncated for brevity. The purpose of this display is to show all possible
fields that might display rather than to show complete output.
Syntax: show ipv6 bgp attribute-entries
For information about display displaying route-attribute entries for a specified BGP4+ neighbor,
refer to
“Displaying BGP4+ neighbor route-attribute entries”
This display shows the following information.
TABLE 4
BGP4+ route-attribute entries information
This field...
Displays...
Total number of BGP Attribute
Entries
The number of entries contained in the Virtual ADX device’s BGP4+
route-attribute entries table.
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 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
•
None – Indicates this 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.
