Check Gateway Failover

tbutcher · Sun Sep 18, 2005 1:51 am

Can somebody explain how the check gateway funtion in routes works? If my understanding is correct it pings the gateway router to see if it is available, however in our case our ISP provides a router which is housed within the building. If our connection fails the router is still available, does this mean check gateway will not work in our situation? Please can somebody suggest and alternative.

Thanks.

you have two possibilities, ping and arp protocols to check gateway.
You can use it to configure fail-over over some gateways, if fails one, etc. switch to main.

That is fine but it doesn't take into account that the gateway router is in the same building and so you will get a ping reply even every state unless the power is lost.

I expect a lot of people will have this scenario where the backhaul provider provides a router.

Not tested but as i understand it will only check for units on same broadcast domain AFAIK. Meaning if there is a router infront then use netwatch(!).
Could be wrong, i mean, recursive route lookups seem to be implemented.
