Displaying BGP4+ information

46

Syntax: show ipv6 bgp neighbor <ipv6-address> attribute-entries

The <ipv6-address> parameter displays the route attribute entries for a specified neighbor. You
must specify this address in hexadecimal using 16-bit values between colons as documented in
RFC 2373.

This display shows the following information:

TABLE 212

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 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 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.
