TABLE 107

This field...

Displays...

Total number of BGP
Attribute Entries

The number of entries contained in the 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.

MED

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 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.
