Floating static-route on ethernet interface


I have a WAN router with 2 ethernet interfaces.

I've configured floating static route to route packet to a gateway out

ethernet0 and a backup route to another gateway out ethernet1.

If ethernet0 interface is down, the router will use the backup route

to forward packets out ethernet1.

However, if only the line-protocol goes down on ethernet0 or the gateway

is unreachable, the router still uses the route out ethernet0.

Is there a way for the router to use the backup route in this situation

without using dynamic routing protocol?


Re: Floating static-route on ethernet interface

as a next hop does your static reference an interface i.e ethernet 0 or a next hop ip address.? If you are referencing an interface try using a next hop ip .

I am using the next hop ip.


Re: Floating static-route on ethernet interface

If the line protocol on the ethernet interface goes down, the router should not use that interface again. I believe the problem (which is common to wireless bridges and modems with ethernet interface) is that the line protocol never goes down when the link does because the interface is still connected to the local modem. The routing protocol suggested is one of the solutions. Another thing to do is to configure two tunnels and configure tunnels keep alives. When the link goes down, the tunnel line protocol goes down also, and the router can then switch to the other link. Note that the routes are pointing into the tunnel intefaces in this case. I would rather go for a routing protocol though.

Re: Floating static-route on ethernet interface

one of the gateway is a windows 2000 server and the other

a pix firewall.

I am not sure if i can create a tunnel between the router

and the windows 2000 server.
