What happens when a load balanced gateway fails?

Matthew Mosteller

We have a PtP wifi link that's pretty robust but does occasionally drop out from circumstances beyond our control (mostly weather) and a really puny DSL.  We've configured it for active/active load balancing with a 10/1 weight and with typical use, during this fine weather, it performs well enough. 

I have two concerns:

One, is that with heavier use they will end up with an important session as the 11th one and suffer with the meager DSL when they don't have to.

The other is that I can't find any info on what happens to a load balanced GW when it fails.  Does then it act like dead active GW in an active/backup configuration and stop trying to handle sessions (and if so, until when, if we haven't configured any active/backup criteria)?  Or does it somehow keep trying to handle it's weight of sessions and just ruin everybody's life until they come back around as the 11th session, or something like that?

Thanks much,

Matthew

    Load Balancing is sticking sessions as you say on the gateway.

    So basically, if you are unlucky, a heavy download can be stick to the slow DSL connection.

    Would recommend to build a Network Policy rule above with only the fast connection. If this gateway fails, the backup interface should take place. 

    If one interface is in state error, xg does not use it anymore for new connections.
