The L2TPv3 feature provides a framework to transport Ethernet pseudowire services over an IPv6-only network without MPLS. This architecture relies on the abundance of address space in the IPv6 protocol to provide unique far-end and local-end addressing that uniquely identify each tunnel and service binding.
L2TPv3 provides the capability of transporting multiple Epipes (up to 16K per system), by binding multiple IPv6 addresses to each node and configuring one SDP per Epipe.
Because the IPv6 addressing uniqueness identifies the customer and service binding, the L2TPv3 control plane is disabled in this mode.
L2TPv3 is supported on non-12e 7750 SR, 7450 ESS, and 7950 XRS platforms.
ETH-CFM is supported for OAM services.
