LDP Peer が張れない

NOTE

Loopback 10.0.0.x/32
[R1]—–(10.1.2.0/24)—–[R2]
R2だけloopback をIGP広報していない

R1#sh ip ro os | b Gate
Gateway of last resort is not set

R1#

R2#sh ip ro os | b Gate
Gateway of last resort is not set

      10.0.0.0/8 is variably subnetted, 4 subnets, 2 masks
O        10.0.0.1/32 [110/2] via 10.1.2.1, 00:10:05, FastEthernet0/0
R2#

どちらも設定は入っているがピアが張れない

R1#sh mp int
Interface              IP            Tunnel   BGP Static Operational
FastEthernet0/0        Yes (ldp)     No       No  No     Yes
R1#sh mp ld nei | inc Peer
R1#

R2#sh mp int
Interface              IP            Tunnel   BGP Static Operational
FastEthernet0/0        Yes (ldp)     No       No  No     Yes
R2#sh mp ld nei | inc Peer
R2#

sh mpls ldp discoveryコマンドでR1はピアのLDPへの経路が無いのが分かる

R1#sh mpls ldp discovery
 Local LDP Identifier:
    10.0.0.1:0
    Discovery Sources:
    Interfaces:
        FastEthernet0/0 (ldp): xmit/recv
            LDP Id: 10.0.0.2:0; no route

R2#sh mp ld dis
 Local LDP Identifier:
    10.0.0.2:0
    Discovery Sources:
    Interfaces:
        FastEthernet0/0 (ldp): xmit/recv
            LDP Id: 10.0.0.1:0
R2#

showコマンド叩く前にループバック間をまとめて確認してしまうほうが早いかもしれない
