VRF support for BGP

The implementation of VRF on the vRouter supports BGP.

If you configure BGP on the vRouter without specifying a VRF instance, the router uses the default routing table. BGP supports route-leaking between VRF's by using route target. To configure BGP for a particular VRF routing instance, specify the instance in the command syntax.

Note: You must configure a unique route distinguisher, before you configure BGP with a VRF routing instance. You cannot further modify the route distinguisher configuration if BGP is already configured within a routing instance. Use the following command to configure a route distinguisher:
vyatta@R1# set routing routing-instance VRF-NAME route-distinguisher RDVALUE

BGP monitor commands log messages from the default VRF, unless the name of the VRF is specified in the configuration of the routing instance.

The following BGP features are supported only on the default routing instance:

  • Extended ASN capability
  • Graceful restart
  • BGP scan timer
  • Cluster ID
  • Confederation identifier
  • Maximum AS limit
