Juniper JUNOSE 11.0.X MULTICAST ROUTING, Configuration Manual

(1 hour), for which the router attempts to maintain dynamic destinations, tunnels,
and sessions after they have been destroyed. The router uses a timeout of 600 seconds
by default.
This command facilitates debugging and other analysis by saving underlying memory
structures after the destination, tunnel, or session is terminated.
Any specific dynamic destination, tunnel, or session may not be maintained for this
entire time period if the resources must be reclaimed early to allow new tunnels to
be established.
TIP: If you use the l2tp destination lockout timeout command to configure an
optional lockout timeout, always configure the destruct timeout to be longer than
the lockout timeout. The destruct timeout overrides the lockout timeout—when the
destruct timeout expires, all information about the locked out destination is deleted,
including the lockout timeout and lockout test settings. See “Managing the L2TP
Destination Lockout Process” on page 360.
■
To specify a destruct timeout:
host1(config)# l2tp destruct-timeout 1200

Preventing Creation of New Destinations, Tunnels, and Sessions
You can configure several L2TP drain operations, which determine how the router
creates new L2TP destinations, tunnels, and sessions. You can manage the following
features:
1. Preventing Creation of New Destinations, Tunnels, and Sessions on the
Router on page 340
2. Preventing Creation of New Tunnels and Sessions at a Destination on page 341
3. Preventing Creation of New Sessions for a Tunnel on page 341
4. Specifying a Drain Timeout for a Disconnected Tunnel on page 341
Preventing Creation of New Destinations, Tunnels, and Sessions on the Router
You use the l2tp drain command to prevent the creation of new destinations, tunnels,
and sessions on the router.
The l2tp drain command and the l2tp shutdown command both affect the
administrative state of L2TP on the router. Although each command has a different
effect, the
no version of each command is equivalent. Each command’s no version
leaves L2TP in the enabled state.
