host1(config)# l2tp drain
Preventing Creation of New Tunnels and Sessions at a Destination
You use the l2tp drain destination command to prevent the creation of new tunnels
and sessions at a specific destination.
The l2tp drain destination command and the l2tp shutdown destination command
both affect the administrative state of L2TP for the destination. 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.
■
To prevent the creation of new tunnels and sessions at the specified destination:
host1(config)# l2tp drain destination ip 172.31.1.98
Preventing Creation of New Sessions for a Tunnel
Use the l2tp drain tunnel command to prevent the creation of new sessions for a
tunnel.
The l2tp drain tunnel command and the l2tp shutdown tunnel command both
affect the administrative state of L2TP for the tunnel. 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.
■
To prevent the creation of new sessions for a specific tunnel:
host1(config)# l2tp drain tunnel virtual-router default ip 172.31.1.98 isp.com
Specifying a Drain Timeout for a Disconnected Tunnel
Use the l2tp tunnel short-drain-timeout command to specify the amount of time
a disconnected LAC L2TP tunnel waits before restarting after it receives a restart
request.
You can specify a drain timeout in the range 0–31 seconds. This feature enables the
router to restart tunnels more quickly than the standard 31-second drain time specified
by RFC-2661. By default, the router uses a short-drain timeout of 2 seconds.
■
To specify the short-drain timeout:
host1(config)# l2tp tunnel short-drain-timeout 12
