Release Information

Statement introduced in Junos OS Release 12.1.

Description

Originate an accumulated interior gateway protocol (AIGP) BGP attribute for a given prefix by export policy, using the aigp-originate policy action.

To originate an AIGP attribure, you need configure the policy action on only one node. The AIGP attribute is readvertised if the neighbors are AIGP enabled with the aigp statement in the BGP configuration.

Default

If you omit the aigp-originate policy action, the node still readvertises the AIGP BGP attribute if AIGP is enabled in the BGP configuration. However, the node does not originate its own AIGP attribute for local prefixes.

As the route is readvertised by downstream nodes, the cost of the AIGP attribute reflects the IGP distance to the prefix (zero + IGP distance or configured distance + IGP distance).

Options

distance—(Optional) Associate an initial cost when advertising a local prefix with the AIGP BGP attribute.

Range: 0 through 4,294,967,295

Default: The initial cost associated with the AIGP attribute for a local prefix is zero. The distance option overrides the default zero value for the initial cost.
