Default

No default route targets. If you do not specify the import or export options at the CLI, by default both is assumed.

Usage Guidelines

This command creates lists of import and export route target extended communities for the specified VRF. Route Target attributes are used to control the VPNv4 route distribution by BGP. Learned routes (from the PE) that carry a specific route target extended community are imported into all VRFs configured with that extended community as an import target. Routes learned from a VRF site are labeled with export route target extended communities configured for that VRF. This is used to control the VRFs into which the route is imported.

A route target extended community can be specified in the following formats:

  • 2_byte_as_num:4_byte_number
  • ip_address:2_byte_number
  • 4_byte_as_num:2_byte_number

To configure multiple route target extended communities in import or export lists, execute this command with add option multiple times, once for each extended community. Use the delete option to remove an extended community from an import or export list. You cannot use this command for a heavy-weight traditional VR.

Example

The following examples configure route target extended communities using the two supported formats:

configure vr corporate-extreme route-target both add 172.16.186.230:9823
configure vr corporate-guest route-target both add 9643:7002
