Network Adapter Failover in Linux?

Posted by Cliff on Sunday November 4, 2001 @02:08PM from the this-does-not-mean-full-HA dept.

Brian the Wise asks: "Is there anything avaible for Linux that can compare to the IP Multipathing in Solaris 8? I need it specifically for the active/passive failover of ethernet interfaces. A search around the net has only come up with HA Linux and LVS, but they're both talking about complete machine failover. All I want is for the system to move the IP configuration from one ethernet interface to a dormant one on the same machine when it detects the link going down on a single machine. Is there anything with a proven track record out there?"

yes linux supports metrics.

however, this method will only work for physical link failures that are detected. (and i dont think linux does much even if it does detect a link failure).

needless to say the vast majority of network failures tend not to be detected link failures.

my suggestion would be to use OSPF for link state and route failure detection and failover.
