Configuring an L2TPv3 Tunnel
Some important points to note about L2TPv3 in the AP context are as follows::
● SCALANCE W supports tunnel and session configuration, and uses Control Message
Authentication (RFC 3931) for tunnel and session establishment. Each L2TPv3 tunnel
supports one data connection and this connection is termed as an L2TPv3 session.
● Each AP supports tunneling over User Datagram Protocol (UDP) only
● If the primary LNS is down, it fails over to the backup LNS. L2TPv3 has one tunnel
profile, and under this a primary peer and a backup peer are configured. If the primary
tunnel creation fails or if the primary tunnel gets deleted, the backup starts. The following
two failover modes are supported:
– Preemptive: In this mode, if the primary comes up when the backup is active, the
backup tunnel is deleted and the primary tunnel resumes as an active tunnel. If you
configure the tunnel to be preemptive, and when the primary tunnel goes down, it
starts the persistence timer which tries to bring up the primary tunnel.
– Non-Preemptive: In this mode, when the backup tunnel is established after the primary
tunnel goes down, it does not make the primary tunnel active again.
You can configure an L2TPv3 tunnel and session profiles through the SCALANCE W UI or
the CLI.
