Refer to the exhibit. A network operator working for a private telecommunication company with an employee id: 7138: 13:414 just added new users to the network, which resides in VLANs connected to routers R1 and R4. The engineer now must configure the network so that routers R1 and R4 share routes to the VLANs, but routers R2 and R3 are prevented from including the routes in their routing tables. Which configuration must the engineer apply to R4 to begin implementing the request?
To configure the network so that routers R1 and R4 share routes to the VLANs, but routers R2 and R3 are prevented from including the routes in their routing tables, you need to use a pseudowire with MPLS encapsulation and specify the neighbor to connect to. The correct configuration for this is: pseudowire-class ciscotest encapsulation mpls interface gigabitethernet 1/0/1 xconnect 192.168.1.1 101 pw-class ciscotest. This configuration ensures that the necessary virtual circuit is established between R1 and R4 without involving R2 and R3.
B looks correct to me: https://www.cisco.com/c/en/us/td/docs/wireless/asr_901s/scg/b_scg_for_asr901s/b_scg_for_asr901s_chapter_010100.pdf
