Can L2TP Be Used in Scenarios Where Active and Standby LNSs Are Deployed?

Can L2TP Be Used in Scenarios Where Active and Standby LNSs Are Deployed?

L2TP can be used in scenarios where active and standby LNSs are deployed. When the active LNS fails, services are switched to the standby LNS. However, L2TP connection requests initiated by the LAC cannot reach the active LNS. To ensure that L2TP connection requests are sent to the standby LNS, you must configure the IP address of the standby LNS on the LAC, so that when the first IP address is unreachable, the LAC sends the request packets to the address of the standby LNS.

You can configure IP addresses of a maximum of four LNSs on the LAC.
