IOS: Static Route on Interface |
|
|
I've got a C2600 where I add a static route on the eth interface.
Why does this static route stay active even when the interface is down?
eg.
interface ethernet 0/0
ip address 192.168.1.1 255.255.255.0
ip route 192.168.100.0 255.255.255.0 192.168.1.10
usually static routes are inactive as soon as the next-hop is unreachable...
thnx |

Simplest answer is the next hop must still be reachable. Can you post a |
show ip route? |

Cisco performs recursive route lookup. So it will look in the routing
table to determine how to reach 192.168.1.10, in order to use that
static route.

you need to include the interface in the static route to achieve this.
for your setup, it would be:
ip route 192.168.100.0 255.255.255.0 eth0/0 192.168.1.10
also, the route now has an admin distance of 0 (directly connected)
instead of 1 (default for static route).
