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:
n
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.
n
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.
L2TPV3 is not supported on IAP-205 devices.
