Displaying BGP4+ information
46
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” on page 1259.
This display shows the following information:
TABLE 204 BGP4+ route-attribute entries information
This field... Displays...
Total number of BGP Attribute Entries The number of entries contained in the switch’s BGP4+ route-attribute
entries table.
Next Hop The IPv6 address of the next hop switch 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 or RIPng.
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 switch 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.
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.
