Question#71


Refer to the exhibit. Router 1 and router 2 are running OSPF Area 0. The router logs on both routers show that the LDP link has flapped. Which configuration must the engineer apply to the two routers to implement session protection on the link?

  • A. Router 1(config)# ip cef distributed Router 1(config)# mpls ldp session protection global Router 2(config)# ip cef distributed Router 2(config)# mpls ldp session protection global
  • B. Router 1(config)# ip cef distributed Router 1(config)# interface gigabitethernet 0/0 Router 1(config-if)# ip address 192.168.1.1 255.255.255.0 Router 1(config)# mpls ldp session protection Router 2(config)# interface gigabitethernet 0/0 Router 2(config-if)# ip address 192.168.1.2 255.255.255.0 Router 2(config)# mpls ldp session protection
  • C.

Question#73

A network engineer is configuring a newly installed PE router at the regional gateway location. The new PE router must use MPLS core routing protocols with the existing P router, and LDP sessions between the two routers must be protected to provide faster MPLS convergence. Which configuration must the engineer perform on the network so that LDP sessions are established?

  • A. Enable RSVP-TE FRR on the LDP interface to protect the LDP session between routers.
  • B. Enable communication over TCP port 646 T-LDP hello messages.
  • C. Set the LDP session protection timer on each router to the same value.
  • D. Enable LDP session protection on either one of the routers, which allows them to autonegotiate.
