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 10.1.2.1Learning materials
