QuestionQ13

EVPN for Layer-3 services

A Layer-3 EVPN service is configured to use the interface-ful, unnumbered forwarding model. Which of the following statements is FALSE?

  • A Each participating PE advertises a MAC/IP route that carries the MAC address of SBD IRB interface.
  • B IP-prefjx routes exchanged between PEs include a non-zero MAC address as an overlay index.
  • C The VPRN service is configured to allow the advertisement of IP prefixes.
  • D The SBD IRB interface configured in the VPRN service has no IP address assigned to it.
Explanation

For interface-ful unnumbered SBD IRB, IP-prefix advertisement is enabled under the BGP-EVPN context of the supplementary broadcast domain (SBD) R-VPLS. The VPRN interface is unnumbered and connected to the SBD by an EVPN tunnel; it does not itself provide the IP-prefix-advertisement configuration. RT-5 routes use the SBD IRB MAC as the overlay index and are resolved through MAC/IP routes.
