  A. the same domain ID value on both PE routers
  B. down bit set for all LSA interarea
  C. the same Site of Origin value on both PE routers

  A. It is used for PIM control traffic.
  B. It is optionally configured for a high bandwidth multicast source to reduce multicast traffic replication to uninterested PE routers.

• Question 720:

  

  Refer to the exhibit. IPTV video clients are connected to R6. Unicast and multicast traffic flows from R1 to R6. The OSPF cost of the R1-R2-R3-R6 path is lower than the R1-R5-R4-R3-R6 path. To enable load sharing and fast reroute, the design team decided to implement MPLS TE tunnels between R1 and R3. After the MPLS TE tunnels are deployed, the multicast traffic stops working.

  While troubleshooting the issue, the operations engineer noticed that the OSPF route to the multicast source is learned via the MPLS TE tunnel, which causes the RPF check to fail. Which two solutions can prevent the multicast traffic from being affected by the RPF check failure due to the MPLS TE tunnel deployment? (Choose two.)

  A. Enable the multitopology routing feature
  B. Enable the multicast-intact feature.
  C. Enable PIM on the MPLS TE tunnel towards the receiver.
  D. Create a static mroute on R3 with the RPF pointing to the MPLS TE tunnel.
  E. Enable the forwarding adjacency feature instead of autoroute announce feature.
  B. Enable the multicast-intact feature.
  D. Create a static mroute on R3 with the RPF pointing to the MPLS TE tunnel.
