Refer to the exhibit.

XR1 and XR2 are sending the prefix 10.11.11.0/24 to XR3. A configured policy on XR1 is incorrectly prepending AS path 11 11 12 12 onto this prefix.

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

A. infinite
B. 0
C. automatic
D. 1

正解：D

質問 # 84
Refer to the exhibit. OSPF is running in the network, which spans multiple areas as shown, and all OSPF neighbors are established. Hosts that reside on the LAN on R1 are trying to reach a server connected to R5, but R1 cannot reach the R5 routes. The server must maintain a TCP connection with the hosts.

A. Configure a virtual link between R1 and R3 to allow area 1 to communicate to area 3.
B. Configure a virtual link between R1 and R2 to connect area 1 to area 0.
C. Configure a static route on R1 and R3 that uses R5 as the next hop for traffic destined to routes connected to R5.
D. Configure a static route on R1 pointing to R3 so that traffic reaches routes connected to R5.

正解：B

質問 # 92
Which statement about BFD on Cisco IOS XR Software is true?

A. BFD is not compatible between Cisco IOS XR and Cisco IOS Software.
B. Cisco IOS XR router must use LDP to route back to the Cisco IOS router to establish the peer relationship.
C. Cisco IOS XR Software does not support BFD multihop for IPv4.
D. Cisco IOS XR router must use dynamic routing or a static route back to the Cisco IOS router to establish the peer relationship.

正解：D

解説：
A router running BFD in Cisco IOS software can designate a router running BFD in Cisco IOS XR software as its peer using the bfd neighbor command; the Cisco IOS XR router must use dynamic routing or a static route back to the Cisco IOS router to establish the peer relationship. https://www.cisco.com/c/en/us/td/docs/routers/crs/software/crs_r6-1/routing/configuration/guide/b-routing-cg-crs-61x/b-routing-cg-crs-61x_chapter_0100.html Reference:
