Need idea how to set L2TP tunnel with two different ISP providers for failover, if ISP1 go down L2TP tunnel connect to ISP2.
There are problem that L2TP tunnel with ISP2 unable connect, Router1 have pcc load balancing failover.

Hello, one possibility is using the RouterOS versin 6.4 that lets you use L2TP Client DNS name instead of fixed IP, so if he ISP1 DOWN name will be updated with the IP s ISp2 enabling closure of tunnel.
