Viewing IPv6 Community Attributes

View IPv6 community attributes for specific routes to utilize the update message fields to communicate information between BGP speakers. The Path Attribute values allow you to specify the prefixes that the BGP session can exchanged, or which of the multiple paths of a specified prefix to use.

Procedure

  1. In the navigation pane, expand Configuration > IPv6.
  2. Click BGP+.
  3. Click the Bgp Route Summary tab.
  4. Select a route for which you want to view the route summary information.
  5. Click the Route Comm Attr option on the menu.

    The BGP Path Attributes tab opens with the BGP IPv6 community attribute information.

BGP Path Attributes field descriptions

Use the data in the following table to use the Community List tab.

Name

Description

Origin

Specifies the ultimate origin of the path information.

NextHopAddr

Specifies the address of the border router that is used to access the destination network. This address is the nexthop address received in the UPDATE packet associated with this prefix.

Med

This metric is used to discriminate between multiple exit points to an adjacent autonomous system. When the MED value is absent but has a calculated default value, this object will contain the calculated value.

LocalPref

Specifies the value used during route decision process in the BGP protocol. Applicable to BGP only.

AggregatorAS

Specifies the AS number of the last BGP4 speaker that performed route aggregation. If the AGGREGATOR path attribute is absent, this object will not be present in the conceptual row.

AggregatorAddr

Specifies the IP address of the last BGP4 speaker that performed route aggregation. If the AGGREGATOR path attribute is absent, this object will not be present in the conceptual row.

String

This is a string representing the autonomous system path to the network which was received from the peer which advertised it. The format of the string is implementation-dependent, and is designed for operator readability.

Note:

SnmpAdminString is only capable of representing a maximum of 255 characters. This may lead to the string being truncated in the presence of a large AS Path.
