Hi. I was wondering if anyone can explain to me the difference between a default route explicitly configured as: ip route s0, and a default router which in turn is configured as: default-router

I know that the default route function, however i can't seem to comprehend the purpose of the default-router command when I already have a default route. Can the default-router command point to a router not physically connected to the router where the command is to be configured?

The default-router is part of a DHCP client configuration tell the client that it's default-gateway is So it used in setting up DHCP scopes for clients.

The "ip route . s0" command is used by the router itself when deciding how to forward packets.

You will also be able to redistribute the s0 into some dynamic routing protocols. Other dynamic routing protocols are able to make use of the default-router, RIP maybe, but I would have to look it up for sure.
