I tried different configurations, but none seems to work.. Can somebody help me? The idea is that when ETH01 goes down ETH03 takes over.

Don`t forget enable STP on bridge interface to avoid switching loops. STP will provide failover. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
