Author static routes

I have a question... After reading and prior experience I am wondering if during the configuration of a static route that you can use the next hop interface instead of the next op ip address? I would think since it is a legal command it is allowed. What say the forum?

You can do that, but it is usually used in WAN or similar configurations. For example, a branch office that uses a point-to-point T1 to connect to corporate. You could use the following:

ip route 0.0.0.0 0.0.0.0 serial 0

that's actually the directly connected interface not the next hop interface.

True, but if it's a point-to-point link, the only interface it could possibly go to is the next hop. However, you are correct. So, I guess the answer to the original question would be no, since the interface names are only locally significant. The configuration in my previous example accomplishes the same thing, though.

yes
yankee's right

serial0 is the local interface
by forwarding the pactets there they will make it
to the other end provided layer1 and 2 are up


your options are
local interface or next hop
local interface does not use recursive routing lookup or arp
and the next hop option does.

thanks all, this does help clear it up.
