The following L2TP control-channel parameters can be configured in L2TP class configuration mode:
• Authentication for the L2TP control-channel
• Password used for L2TP control-channel authentication
• Retransmission parameters used for control messages.
• Timeout parameters used for the control-channel.
• Maintenance Parameters
• L2TPv3 Control Message Hashing
Perform this task to create a template of L2TP control-channel parameters that can be inherited by different
pseudowire classes.
