Static Routes Question

mattipler

If I want to set a static route to network. Is there any difference in setting the static route to exit out of the router interface in the direction of the network say

ip route 10.10.10.0 255.255.255.0 fa0/0

to putting the next hop router in the direction of the network ie.

ip route 10.10.10.0 255.255.255.0 192.168.10.10

Would either route be considered better or more reliable? There just the same aren't they?

I hope that makes sense.

Cheers to anyone who replies.

Be careful using an exit interface that is a multi-access network, it's not reliable because finding the next hop may depend on proxy arp. Imagine an Ethernet network with 5 routers all leading to different remote subnets, how would the router sending the frame know what mac addresses to put on the frame to forward it to the correct next hop router?

Now, the case of a point to point interface (serial, p2p subinterfaces on frame, ISDN, atm, ect) you can use an exit interface and it works fine. The other thing is when you use an exit interface in a static route, it shows as directly connected with an administrative distance, and will be advertised by a routing protocol if it happens to fall in a network statement (go figure)
