A network engineer must configure an LDP neighborship between two newly installed routers that are located in two different offices. Router 1 is the core router in the network and it has already established OSPF adjacency with router 2. On router 1 and router 2. interface fa0/0 is configured for BFD. Which additional configuration must the engineer apply to the two devices to meet the requirement?
A. Router1(config)#int fa0/0 - Router1(config-if)#mpls ldp autoconfig Router2(config)#router ospf 1 - Router2(config-router)#mpls ip
B. Router1(config)#int fa0/0 - Router1(config-if)#mpls ip Router1(config-if)#mpls ldp discovery transport-address interface Router2(config)#int fa0/0 Router2(config- if)#mpls ip Router2(config-if)#mpls ldp discovery transport-address interface
C. Route1(config)#int fa0/0 - Router1(config-if)#mpls ldp autoconfigRouter1(config-if)#mpls ldp discovery interface Router2(config)#router ospf 1 Router2(config- router)#mpls ldp autoconfig Router2(config-if)#mpls ldp discovery interface
D. Router1(config)#int fa0/0 - Router1(config-if)#mpls ip - Router2(config)#router ospf 1 Router2(config-router)#mpls ldp autoconfig
