QuestionQ14

EVPN for Layer-3 services

An operator configures EVPN-IRB using the interface-ful unnumbered forwarding model on a Nokia 7750 service router. Which of the following statements about the configuration on each participating PE is FALSE?

  • A A supplementary broadcast domain (SBD) is configured as a routed VPLS.
  • B A VPRN service is configured and has an interface bound to the local VPLS.
  • C The advertisement of IP-Prefix routes is enabled in the SBD VPLS.
  • D An IP address is configured in the VPRN Interface that is bound to the SBD VPLS.
Explanation

In the interface-ful unnumbered SBD IRB model, the SBD is an R-VPLS linked to a VPRN interface through an EVPN tunnel, and BGP-EVPN IP-prefix route advertisement is enabled. Because the SBD IRB is unnumbered, no IP address is configured on that VPRN interface; prefix routes use a zero gateway IP and the router MAC extended community instead.
