Hi I am currently having trouble with a networking question.

I need to create a backup default route leading to a router (172.20.156.16) but it needs to have an administrative distance of 3. Where would the AD even go, does it go on the end?

Current route:

Ip route 10.166.16.61(destination PC) 0.0.0.0 172.21.166.16 (destination router) 3

So it looks like this:

Ip route 10.166.16.61 0.0.0.0 172.21.166.16 3

Would this be the correct floating route that has an administrative distance of 3?
