An engineer is implementing LFA FRR on PE routers to allow unicast traffic to rapidly converge around link or node failures. The engineer configured IS-IS on the newly deployed routers in the data center in the same exchange as other routers. Which additional action must the engineer take before configuring LFA on the PE routers?

• A.Configure the isis network point-to-multipoint command on each router.
• B.Configure the isis network point-to-point command on each router.
• C.Configure MPLS on each router.
• D.Configure IP Cisco Express Forwarding on each router.

Refer to the exhibit.

Refer to the exhibit While troubleshooting a networking issue an engineer identified a suboptimal communication issue on route reflector RR2 In the current environment Router A is a non-route-reflector client for RR1 and RR2 Routers D and E are directly connected iBGP peers.
Router F is not an iBGP peer of routers D and E
Which action resolves the issue?

• A.Enable next-hop-self for BGP peering on router D.
• B.Enable next-hop-self for BGP peering on router C.
• C.Remove the route-reflector configuration on router RR2.
• D.Disable BGP Client-to-Client reflection on router RR2.

Which difference should be considered when intradomain or interdomain multicast routing is implemented?

• A.A network uses intradomain multicast routing without interdomain routing but networks that use interdomain multicast routing must also apply intradomain routing
• B.Interdomain multicast routing relies on PIM-DM and intradomain multicast routing relies on PIM-SM.
• C.interdomain multicast routing uses BIDR-PIM to establish neighbor relationships between AS and interdomain multicast routing uses MSDP
• D.Interdomain multicast routing requires an IS-IS or OSPF neighbor relationship between the domains but intradomain multicast routing requires only BGP
