https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/mp_te_path_setup/configuration/xe-16/mp-te-path-setup-xe-16-book/mpls-traffic-engineering-The Cisco MPLS TE (Traffic Engineering) forwarding adjacency feature is a mechanism used to create TE tunnels through an MPLS (Multiprotocol Label Switching) network. These tunnels can be used to steer traffic across the network in a more efficient way than traditional IP routing protocols.
Answer B is correct: The Cisco MPLS TE forwarding adjacency feature enables the Cisco MPLS TE tunnel to be advertised into the running IGP (Interior Gateway Protocol). This means that the TE tunnel can be used by other routers in the network to forward traffic to its destination.
Answer A is incorrect because the Cisco MPLS TE forwarding adjacency feature does not enable the MPLS core to use EIGRP (Enhanced Interior Gateway Routing Protocol) as the routing protocol. MPLS networks typically use OSPF (Open Shortest Path First) or IS-IS (Intermediate System to Intermediate System) as the routing protocol.
Answer C is incorrect because the tailend router (the router at the end of the TE tunnel) does not advertise routes to the headend router (the router at the beginning of the TE tunnel) over the tunnel. The headend router is responsible for steering traffic through the tunnel to its destination.
Answer D is incorrect because the Cisco MPLS TE forwarding adjacency feature does not establish bidirectional tunnels. Instead, it enables unidirectional tunnels to be created between the headend and tailend routers.
In summary, the Cisco MPLS TE forwarding adjacency feature enables the Cisco MPLS TE tunnel to be advertised into the running IGP, allowing other routers in the network to use the tunnel to forward traffic to its destination.
