difference between using IP unnumbered and using IP's

[kcmusa108]

I have a G2 router with the sm-700 for remote site and an appliance for the date center.

I followed the quick config guide and have it all working. This is using IP's on the interface SM1/0. for the router SM

Then I wanted to try it with IP unnumbered on interface SM1/0, cant get it to work.

WCCP packets are not increasing when I run wccp statistics on the device.

the router config looked like this;

int g0/0

ip address 10.1.1.1 255.255.255.0

int sm1/0

ip unnumbered g0/0

service-module ip address 10.1.1.240 255.255.255.0

service-module ip default-gateway 10.1.1.1

ip route 10.1.1.1 255.255.255.255 SM1/0

does this look right?

This statement does not look correct to me:

ip route 10.1.1.1 255.255.255.255 SM1/0

You need to put a route towards SM IP in this statement, that is:

ip route 10.1.1.240 255.255.255.255 SM1/0

See http://www.cisco.com/en/US/partner/docs/routers/access/interfaces/software/feature/guide/ism-sm-sre.html#wp1056674 for example.
