failover-protocol—Tunnels use the L2TP failover protocol method. If the peer non-failed
endpoint does not support the L2TP failover protocol, a failover forces disconnection
of all tunnels and their sessions.
failover-protocol-fallback-to-silent-failover—Tunnels use the L2TP failover protocol
method; however, if the peer non-failed endpoint does not support the L2TP failover
protocol method, the tunnel falls back to using the silent failover method.
silent-failover—Tunnels use the silent failover method. The tunnels also inform their
peers that they support the failover protocol method for peer failovers.
disable—Tunnels do not use any peer resynchronization method for their own failovers.
Tunnels inform their peers that they support the failover protocol method for peer
failovers. A failover forces the disconnection of all tunnels and sessions.
Use the show l2tp command to display the global peer resynchronization configuration.
To configure peer resynchronization for an L2TP host profile or AAA domain map tunnel:
host1(config)#l2tp failover-resync silent-failover
To restore the global default setting, which uses the
failover-protocol-fallback-to-silent-failover method:
host1(config)#default l2tp failover-resync
To disable peer resynchronization, use the no version of the command—this is the
same as using the disable keyword:
host1(config)#no l2tp failover-resync
The JunosE Software supports the use of RADIUS to configure the L2TP peer
resynchronization method used by your L2TP tunnels. You use the L2TP-Resynch-Method
RADIUS attribute (VSA 26-90) in RADIUS Access-Accept messages to specify the L2TP
peer resynchronization method.
Table 69 on page 391 describes the L2TP-Resynch-Method RADIUS attribute. For more
information about RADIUS Access-Accept messages, see "Configuring RADIUS Attributes"
on page 167. For more information about the L2TP-Resynch-Method attribute, see "RADIUS
IETF Attributes" on page 255.
