Configuring retransmission of L2TP control messages

L2TP peers maintain a queue of control messages that must be sent to the peer device. After a message is sent, the local peer waits for a response from the remote peer. If a response is not received, the local peer retransmits the message. One can configure how many times an unacknowledged message is retransmitted by the LAC or the LNS.
