How to Implement Layer 2 Tunnel Protocol Version 3

Like-to-Like Pseudowires

A PseudoWire (PW) is a bidirectional virtual circuit (VC) connecting two Attached Circuits (ACs). In an
MPLS network, PWs are carried inside an LSP tunnel.
The ATM like-to-like pseudowires support the following modes:
A point-to-point (PPP) connection allows service providers to provide a transparent PPP pass-through where
the customer-edge routers can exchange the traffic through an end-to-end PPP session. Service providers can
offer a virtual leased-line solution, and use the PPP subinterface capability to peer with multiple providers
through a single POS connection.
Note In an MPLS network, pseudowires are carried inside an LSP tunnel.

This section includes the tasks required to implement L2TPv3, as follows:

Configuring a Pseudowire Class

Perform this task to configure a pseudowire class, or template.
SUMMARY STEPS
1. configure
2. l2vpn
3. pw-class class name
4. encapsulation { mpls | l2tpv3 }
5. protocol l2tpv3 class class name
6. ipv4 source ip-address
7. transport-mode { ethernet | vlan }
8. Use the commit or end command.
DETAILED STEPS
Step 1
configure
