show ip route issues

Unanswered Question
Aug 7th, 2008

Does anyone know why when i show ip route to an internet address on a 6513 that has a static route 0.0.0.0 0.0.0.0 to my default gateway firewall. it shows route is not found in the routing table?

I have this problem too.

That's expected behaviour.

When you do a 'show ip route' for a specific destination, it would show you the next hop to reach that destination if it has one or would say '%subnet not in table'.

Default route is used when you do not have a route for a destination, so its technically not a route for that destination, its a gateway of last resort, kind of a dumyard for any unknown destinations.

Because the route is not in the routing table.

A default route will instruct the device to send all unknown routes over to the gateway. It does not populate the routing table with 'internet' routes.
