Notater

Når to routere laver en LDP session mellem naboer bruges højeste Loopback adresse. Derfor skal naboen kende denne adresse. Brug 

R3(config)#<input>mpls ldp router-id loopback 0</input>

Check at LDP til naboen er oppe 

R3#<input>sh mpls ldp neighbor</input>
    Peer LDP Ident: 10.1.2.1:0; Local LDP Ident 10.1.5.1:0
        TCP connection: 10.1.2.1.646 - 10.1.5.1.51150
        State: Oper; Msgs sent/rcvd: 1785/1777; Downstream
        Up time: 1d01h
        LDP discovery sources:
          Serial0/0, Src IP addr: 10.1.1.10
        Addresses bound to peer LDP Ident:
          10.1.1.25       10.1.1.10       10.1.2.1
