IntraVlan routing

i have a 5304 switch connected to a old Digital router, and OSPF is up and running.

on the 5304 i have 2 vlan with a relative ip address.

Why the switch doesn't see the second vlan as "connected"?
As you can see in the attached Sho ip route, the entry for the network 10.10.123.0 is not present.
The result is that the switch is not able to ping it self of 10.10.123.1.


attacher the configuration and the sho ip route.
