Specifying the Number of Retransmission Attempts

You can specify the number of retransmission attempts the router uses for tunnels, in the range 2–30. By default, the router uses a retry count of 5.

Use the established keyword to apply the retry count only to established tunnels. Use the not-established keyword to apply the retry count only to tunnels that are not established. If you do not include a keyword, the router applies the retry count to both established and nonestablished tunnels.

• To configure the number of retransmission attempts:
  host1(config)#l2tp retransmission 4 established

If you perform a stateful SRP switchover on an LNS device, we recommend that you configure the maximum number of retransmission attempts as 10, although the default number of attempts is 5. This recommendation applies for all types of L2TP peer resynchronization methods configured for LNS devices.
