C. Execute the traceroute utility to generate information about the labels used along the path

D. Verify that Cisco Express Forwarding has been disabled on the network

What is the function of BGP confederations?

A. They require routers to use private AS numbers.

B. They eliminate the need for a fully-meshed internal BGP design.

C. They enable a single device to distribute a common configuration to its peers

D. They assign an external BGP router to serve as the route reflector

After you change the IP address on an IOS XR router, you cannot ping the new address.

The four routers in this network have formed adjacencies. Router R2 is an IS-IS level 1-2 router that connects to other areas, and the attach bit is set in the R2 level 1 LSP advertisements to R1. According to the network design, R2 should push level 2 routes from its routing table to the R1 routing table. However, R1 installed a default route in its routing table. Which action resolves this problem?

A. Use The is-type level-1-2 backdoor command lo unset the attach bit on R1 and use a prefix List to filter prefixes from R2

B. Set the attach bit on R1and use a prefix list to filter prefixes from R2.

C. Use the is-type level-1-2 backdoor command to unset the attach bit on R2 and configure a distribute-list to redistribute prefixes to R1

D. Configure R2 as a level 1 router and use a prefix list to filter prefixes to R1.

Refer to the exhibit.

OSPF is running in the core of a company. Router RA is running EIGRP. After the company acquired an additional office, an engineering team connected the two networks from router RA to router R1. OSPF and EIGRP have been mutually redistributed on R1. but the team cannot view the routes on R3. Which action must the team take to resolve the issue?

A. Create a virtual link between R1 and R2.

B. Configure the routers in Area 2 to be in Area 0.

C. Disable stub routing in Area 1.

D. Redistribute connected routes on R3.

Refer to the exhibit.

The Cisco router has a single uplink to the upstream network, which is critical to the business. The router is configured for traffic steering with the Autoroute mechanism configured to steer all OSPF and IS-IS prefixes over non-shortest paths and divert traffic for those prefixes to the SR-TE policy. However, the Autoroute Announce functionality for all prefixes is not working. Which additional command set must the engineer configure on the router to correct this issue?

A. Option A

B. Option B

C. Option C

D. Option D

An ISP has an MPLS VPN-based network with 12 PE routers. How many peerings are required between the 12 routers if the engineer has not configured route reflectors?

A. 60

B. 66

C. 78

D. 84

Refer to the exhibit.

A network engineer is configuring router R3 to handle multicast streams, but Host-2 cannot send subscriptions messages to the IPTV source. Which configuration must the engineer apply to router R3 so it passes the IPTV stream to Host-2?

A. Option A

B. Option B

C. Option C

D. Option D
