Parameters
ip-address: Specifies the source IP address of L2TP tunnel packets.
Usage guidelines
This command is available only on an L2TP group in LAC mode.
As a b est practice to ensure high availability, use the IP address of a l oopback interface as the
source IP address of L2TP tunnel packets.
Examples
# Configure the source IP address of L2TP tunnel packets as 2.2.2.2.

Parameters
seconds: Specifies the interval at which the LAC or the LNS sends keepalive packets, in the range of
0 to 32767 seconds.
Usage guidelines
A virtual PPP interface sends keepalive packets at keepalive intervals to detect the availability of the
peer. If the interface fails to receive keepalive packets when the keepalive retry limit is reached, it
considers the link faulty and reports a link layer down event.
To set the keepalive retry limit, use the timer-hold retry command.
On a s low link, increase the keepalive interval to prevent false shutdown of the interface. This
situation might occur when keepalive packets are delayed because a l arge packet is being
transmitted on the link.
