Your organization manages a Layer 3 VPN for multiple customers. To support advanced route filtering on your PE routers, you must advertise more than one BGP community on advertised VPN routes to remote PE routers.
Which routing-instance configuration parameter would support this requirement?
To advertise more than one BGP community on VPN routes to remote PE routers, the appropriate routing-instance configuration parameter would be 'vrf-target export.' This parameter allows for the inclusion of multiple BGP communities in the route advertisement, ensuring effective route filtering. Using 'vrf-target' in the export context specifies the communities to be attached to outgoing routes, fulfilling the requirement for advanced route filtering.
With vrf-export you could configure a policy that would let you do some "advanced filtering" and set more than one BGP community. With vrf-target export you can't do filtering, you just set one or more BGP communities to all prefixes.
