From this figure, it can be known that

There is the concept of forwarding equivalence class FEC in MPLS. The following description is wrong:

As shown in the figure, the MP_BGP neighbor relationship is established between PE1 and PE2 through the LoopbackO interface. After the configuration is complete, it is found that CE1 and CE2 cannot learn routes from each other. Which of the following options will cause this problem.

On the network shown in the figure, EBGP peer relationships are established between neighboring routers through directly connected interfaces. The AS number is 6500X, where X is the number of the router. Both Rl and R4 have static routes to 192.168.1.0/24, which are imported to BGP through the import-route command. By default, in the routing table of R3, which of the following is the AS_Path attribute carried in the route to 192.168.1.0/24?

On the network shown in the figure, IS-IS runs on Rl, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. In AS 65000, Ri, R3, R4, and R6 each establish IBGP peer relationships with R2 and R5. R2 and R5 are RRs, and Rl, R4, R3, and R6 are clients. The IBGP peer relationships are established using LoopbackO. The IP address of LoopbackO on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router. Rl and R4 import the external route 192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command. Which of the following statements are true?

BGP allows you to use the filter-policy acl-number import command to filter received routes. The value of ad-number ranges from 2000 to 3999.

As shown in the figure, the network has a loop because STP is not enabled. Which of the following phenomena may be bowed?

In an MPLS VPN network, data packets are forwarded when they enter the public network. will be encapsulated with two layers of MPLS labels sign. Which of the following options describes the processing of the packet correctly:

The rules of RR advertising routes violate the rules of IBGP split horizon, so it may cause loops in the AS

road. Which routing attributes does RR use to prevent loops?
