How does a PE router know in which VRF table to install received routes for a customer?
- Customer routes are identified by the RT contained in the extended BGP community.
- Customer routes are identified by the MED.
- Customer routes are identified by the RD contained in the extended BGP community.
- Customer routes are identified by the metric.
Explanation: Route Targets (RTs) are used as identifiers to indicate VPN membership and are encoded as extended BGP communities. When a PE router receives MP-BGP updates, it uses the attached RTs to decide which routes to import into specific VRF tables based on the import RTs configured for those tables.
