L2TPv3 service tunnels

Overview

L2TPv3 transport tunnels enable the encapsulation of L2 Ethernet frames into IPv6 packets transported by L2TPv3. L2TPv3 tunnels provide services similar to Ethernet pseudowire services but without the use of MPLS encapsulation and labels for network and service offerings that are IPv6-only, with no MPLS or IPv4 services.

L2TPv3-encapsulated traffic is transported over the IPv6 address family, without using any session or label identifier or signaling control plane.

Consider the following when you create an L2TPv3 tunnel:

• you must enable the IPv6 Allowed and Loopback Enabled parameters on the network interface of the NE

• you can configure multiple IPv6 addresses on the loopback interface

• you can add the loopback interfaces as ISIS and OSPFv3 routing instances so that the IGP is used to route the traffic between loopback interfaces

• you can configure an address aggregation policy to distribute the loopback interface IP addresses

Only Epipe spoke and mirror SDP bindings can use L2TPv3 tunnels. See To configure a spoke SDP binding with an L2TPv3 tunnel on a VLL Epipe site for more information about how to create an Epipe SDP binding with an L2TPv3 tunnel. See To create a destination site on a mirror service for more information about how to add a remote source mirror SDP binding on a mirror destination site with an L2TPv3 tunnel. See To create a source site on a mirror service for more information about how to create a mirror SDP binding on a mirror source site with an L2TPv3 tunnel.
