MPLS and Segment Routing

Question Image

Refer to the exhibit. Router 1 is a core ABR in a Cisco Unified MPLS environment. All Router 1 BGP peers are established, but customer-to-customer traffic is failing. Which BGP configuration must be added?

  • A It must be configured for graceful restart
  • B It must be configured with a route reflector
  • C It must be configured with send labels
  • D It must be configured with PIC edge
Explanation

Cisco Unified MPLS uses BGP labeled-unicast (RFC 3107) to advertise routes together with their MPLS label mappings, creating the end-to-end labeled path required for customer VPN traffic. Enabling BGP to send labels provides that label exchange; an established unlabeled BGP session alone does not.
