Tasks

Configure and verify an OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals:

1. R1 pings the Loopback0 interface of R2. Use interface-level configuration to complete this task.

2. R2 pings the Loopback0 interface of R1. Use interface-level configuration to complete this task.

3. R2 receives a single summary route 172.16.100.0/22 for networks 172.16.100.0/24, 172.16.101.0/24, and 172.16.103.0/24.

Refer to the exhibit. Routers R1. R2, R3. and R4 are peer routers that reside in different administrative domains. PIM-SM is running in each autonomous system, and EBGP is configured between the peers. A network administrator has just implemented MSDP between the connected peers. When the administrator enabled the MSDP configuration. R1 and R2 failed to establish a peering relationship. All other connected routers successfully established peering sessions Which action must the engineer take to resolve the issue between R1 and R2?

Refer to the exhibit. A network engineer is investigating a report of packet drops in an application running on a server connected to PE2 The engineer determined that:

The OSPF adjacency in area 0 is up. and it is learning the loopback addresses of all routers in area 0.

Traffic from users connected to PE1 to the application is also passing normally.

Packets from PE2 back to PE1 are being dropped

Which action resolves the issue?

Refer to the exhibit. HostB receives an IPTV traffic stream from the multicast source at 192.168 10.1. When router RB is powered down, it impacts multicast traffic forwarding to downstream peers. The RA and RB routers reside in the same physical location. Which two configurations must be implemented so that HostB receives the multicast stream even when RB is powered down? (Choose two )

Refer to the exhibit. Users connected to an application on 1.1.1.1 via routers CE1 and CE2 are complaining of frequent disconnections. While troubleshooting the issue, a network engineer with an employee ID: 4333:96:916 determined that the application itself is working normally, but the link connected to the 1.1.1.1 application is flapping. The users on CE1 and CE2 are accessing applications on 2.2.2.2 without difficulty. Which action resolves the issue?
