l2tp hello
To specify the use of a hello keepalive setting contained in a specified Layer 2 Tunneling Protocol class
configuration for a static Layer 2 Tunnel Protocol Version 3 (L2TPv3) session, use the l2tp hello
command in xconnect configuration mode. To disable the sending of hello keepalive messages, use the
no form of this command.

no l2tp hello l2tp-class-name
Syntax Description
Defaults No hello keepalive messages are sent.
Command Modes Xconnect configuration
Command History
Usage Guidelines Because a static L2TPv3 session does not use a control plane to dynamically negotiate control channel
parameters, you must use the l2tp hello command to specify an L2TP class configuration that contains
the interval for sending hello keepalive messages.
Examples The following example shows how to configure the time interval for hello keepalive messages stored in
the L2TP class configuration named l2tp-defaults for an Ethernet interface using the configuration
settings stored in the pseudowire class named ether-pw:
Router(config)# interface Ethernet 0/0
Router(config-if)# xconnect 10.0.3.201 123 encapsulation l2tpv3 manual pw-class ether-pw
Router(config-if-xconn)# l2tp hello lt2p-defaults
Related Commands
l2tp-class-name Specifies the L2TP class configuration in which the hello keepalive interval
to be used for the L2TPv3 session is stored.
