VOSS static route overide

[treese]

I have fabric extend to a remote branch with the remote site learning the quad zero ISP default route from the far end location.  I setup a static route at the branch end so local users can use the local ISP default route.  I have a route-map built so the local default route won't get advertised/redistributed into ISIS.  

Here is the problem i'm trying to solve now.  If/when the local ISP goes down, I'd like the alternative route (quad zero router from far end) working so the local users will have internet access via the fabric.  The current solution to fix this is to remove the static route then the alternative routes pick up.  

Thanks for your help

Hi,

If the ISP WAN fails the default route may still alive because the next-hop (ISP LAN) is reachable.

I belive that VOSS hasn´t some similiar to route tracking so we solve it running an script over XIQ-SE that test regular some internet IPs (ex.: 8.8.8.8) if it is not rechable, the script connect to VSP and deletes the route.

Any other idea?

Do you mind sending me the details on your script?  Our XIQ-SE lives on the other side of the fabric extend so I'm not certain its the best solution.  I'm thinking I may need to change the static routing to a routing protocol and check the preferences.

Yes when the direct internet is down the route is still in the table, that is the issue I'm attempting to resolve.
