Using RADIUS to Configure Peer Resynchronization
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 388 describes the L2TP-Resynch-Method RADIUS attribute. For more
information about RADIUS Access-Accept messages, see "Configuring RADIUS
Attributes" on page 165. For more information about the L2TP-Resynch-Method
attribute, see "RADIUS IETF Attributes" on page 253.

Configuring L2TP Tunnel Switch Profiles
You can use the l2tp switch-profile command to create an L2TP tunnel switch profile.
An L2TP tunnel switch profile is a set of characteristics that defines the behavior of
L2TP tunnel switching for the interfaces to which the profile is assigned.
Within the L2TP tunnel switch profile, you configure a particular tunnel switching
behavior for a specified L2TP AVP. For example, you can configure the router to
preserve the value of (relay) a specified AVP type across the LNS/LAC boundary in
an L2TP tunnel-switched network.
Applying the L2TP Tunnel Switch Profile
Configuring an L2TP tunnel switch profile has no effect by itself. To use the tunnel
switch profile in an L2TP tunnel-switched network, you must apply it to an L2TP
outbound LAC session by using one of the following methods:

Using RADIUS to Configure Peer Resynchronization
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
