- The LDP session must remain operational for one hour when the WAN link on PE-XR1 fails.
Which configuration must the team implement on PE-XR1?

A. configure terminal ipv4 access-list LDP-SESSION-PROTECTION permit ipv4 172.31.255.0 0.0.0.255 any ! mpls ldp session protection for LDP-SESSION-PROTECTION duration 60 end B. configure terminal ipv4 access-list LDP-SESSION-PROTECTION permit ipv4 172.31.255.0 0.0.0.255 any ! mpls ldp session protection for LDP-SESSION-PROTECTION duration 3600 end C. configure terminal ipv4 access-list LDP-SESSION-PROTECTION permit ipv4 172.31.255.0 0.0.0.255 any permit ipv4 10.0.0.0 0.0.255.255 any ! mpls ldp session protection for LDP-SESSION-PROTECTION duration 60 end D. configure terminal ipv4 access-list LDP-SESSION-PROTECTION permit ipv4 172.31.255.0 0.0.0.255 any permit ipv4 10.0.0.0 0.0.255.255 any ! mpls ldp session protection for LDP-SESSION-PROTECTION duration 3600 end
