Static route path monitoring recovery

treese — Thu, 30 Aug 2018 15:40:00 GMT

I've configured static route path monitoring on primary ISP. When it if fails secondary ISP comes up. Do I need to configure static route path monitoring on secondary ISP for primary to come back when the circuit recovers?

Thank you

Hello,

You do not need to.

It will come back on its own when the monitor determines the conditions are correct.

What if the monitoring IP's are not within the source interface subnet range? Say for instance I monitor public dns servers like 8.8.8.8/4.2.2.2 from my source ISP interface which has a public /30. Do I need to have a seperate static routes for destination 8.8.8.8/4.2.2.2 pointing to that ISP interface next-hop?

Hello,

Typically, the default route handles this, but if you do not have one, then yes you will need additional static routes. The monitor IP's can be anything as long as they are reachable.

Hope that clarifies things.
