Remove default static route if path is not available

[PavelAfanasjev]

Hello,

We have a location with an internet line and default route to it.

Additionally we have OSPF routing in place over L2 link to the DC that also has internet access and injected default route.

Due to metrics, static default route is preferred.

What is the best way to have statically configured default route removed when Internet line is down to be able to route through the DC by OSPF default route?

Thanks,
