Configuring WINS Servers
To configure redundant Domain Name System (WINS) servers for L2TP tunnels, do the following:
1. Make sure the CLI is in Configuration mode.
2. Configure the primary and secondary WINS servers by typing:
tunnel l2tp WINS-server primary primary-ip secondary secondary-ip
Where:
• primary-ip is the IP address of the primary WINS server
• secondary-ip is the IP address of the secondary WINS server

Section 12.4
Managing L2TPv3 Tunnels
L2TPv3 (Layer 2 Tunneling Protocol Version 3) provides a pseudo-wire service that encapsulates multi-protocol
Layer 2 traffic over IP networks. There are no restrictions on the Layer 2 data formats that can be transmitted or
received, unlike L2TP.
L2TPv3 is a simplified alternative to MPLS (Multiprotocol Label Switching) that offers improved performance (e.g.
high data packet rate and low CPU consumption) over L2TP and and IP network.
Two types of L2TPv3 tunnels are available:
• Static
A static L2TPv3 tunnel is a fixed connection between two Provider Edge devices (PE), where the session IDs
and cookies are defined on both devices. This allows the devices to route Layer 2 traffic as soon as the session
connects with the attachment circuit.
• Dynamic
A dynamic LTPv3 tunnel creates sessions based on the dynamic exchange of control messages between the PE
devices to determine the type of Layer 2 traffic that needs to be routed. Session IDs and cookies are generated
by the devices themselves for each session. This allows L2TPv3 to reestablish sessions automatically in the case
of a network failure.
