B. Configure rp-set for the Anycast RPs.
C. Configure multicast BGP between the Anycast RPs.
D. Configure the network to always use the RPT and not switch over to the SPT.

Referring to the exhibit, you are configuring an OSPF network. All OSPF adjacencies come up and stay stable. But neither R1 nor R2 has the prefix 200.200.200.200/32 in its routing table.
What is causing this problem?
A. R2 does not have the export policy for prefix 200.200.200.200/32.
B. R1 does not have routes to network 172.10.1.0/24.
C. R2 is BDR on both network 172.10.1.0/24 and 172.20.1.0/24.
D. The router ID of R1 is the same as the router ID of R3.

A customer reports that BGP graceful restart is not working on R1. After a Routing Engine failover, R1 did not set the restart state bit in its Open message. The customer provides the BGP neighbor output shown in the exhibit.
Referring the exhibit, what is causing this problem?
A. BGP graceful restart is not enabled on R1.
B. BGP graceful restart is not enabled on the peer device.
C. The restart duration time is not configured on R1.
D. The restart duration time is not configured on the peer device.

The policy shown in the exhibit is deployed on a router and used as the only BGP export policy. The router
is sending only one BGP route to its peers. However, when you run the CLI command test policy accept-
static 0.0.0.0/0, the policy matches thousands of routes.
Which statement explains this discrepancy?
A. All policies have an implicit then accept final term.
B. The default policy for BGP is to reject all routes.
C. The default policy for the test policy command is to accept all routes.
D. The test policy command always shows all routes, regardless of whether they match the policy, when you use the 0.0.0.0/0 argument.

-- Exhibit -Click the Exhibit button. Your network has two connections to your ISP. You have been asked to load-balance traffic across both
links that connect to your ISP. You have enabled multipath for this peer, but you are still not getting the
expected load balancing.
Given the information shown in the exhibit, what else must you do?
A. Configure and apply a load-balancing policy.
B. Change the multipath parameter to multihop.
C. Create a policy to manually change the next hops.
D. Enable the keep all parameter.
Referring to the exhibit, an administrator has configured dot1q-tunneling on the VLAN, but LLDP is not being tunneled.
What is causing the problem?
A. LLDP needs to be enabled as a protocol to tunnel.
B. LLDP can only be processed one hop away.
C. LLDP needs to be disabled on the tunneling device.
D. LLDP tunneling only works on trunked interfaces.
Referring to the exhibit, the prefix 3.3.3.3/32 is not in R1 's routing table. Which two configuration changes on R2 would resolve the problem? (Choose two.)

B. Option B
C. Option C
D. Option D
