Configures fast-failover support on the L2TPv3 tunnel. When configured, devices, using this profile, send tunnel requests to both peers, and in turn, establish tunnels with both peers. If not configured, tunnel establishment occurs on one peer, with failover and other functionality the same as legacy behavior. In case fast failover is configured when an active tunnel, with one peer, already exists, the tunnel establishment process is re-initiated with both peers. Of the two tunnels established, one is marked active while the other is standby. The sessions and routes from the active tunnel are only pushed to the dataplane, resulting in creation of data sessions. However, if the active tunnel fails, sessions and routes from the standby tunnel are pushed to the dataplane thereby providing almost immediate fail over. Both tunnels individually perform connection health checkups through hello intervals. This option is disabled by default.

| fast-failover | Configures fast-failover support on the L2TPv3 tunnel |
| aggressive | Optional. When enabled, tunnel initiation hello requests
are set to zero. For failure detections, hello attempts are not retried, regardless
of the number of retry attempts configured. This option is disabled by
default. Note: The hello-interval and retry-attempts parameters are defined in the
L2TPv3 Policy context. For more information on configuring an L2TPv3 policy, see
l2tpv3-policy-commands. For more information on
associating an L2TPv3 policy to an L2TPv3 tunnel, see use.
