L2TPv3 layer 2 tunneling protocol: Tunnel over IP network
ethernet
frame relay
atm
hdlc
ppp
Non richiede MPLS Core network
AToM (Any Transport over MPLS): Tunnels P2P over MPLS network
ethernet
frame relay
atm
hdlc
ppp
Richiede MPLS Core network
trasporto labels attraverso LDP / MPLS-TE / BGP + label path
VPN label rappresenta una nuova etichetta “pseudowire” automaticamente allocata attraverso una LDP session tra nodi PE
L2TPv3 ed AToM, quindi permette un any to any layer 2 tunneling:
Ethernet to ATM
Ethernet to FR
Ethernet to PPP
ATM to FR
ATM to PPP
PPP to FR
