You can advertise a secondary IP only if the primary is advertised as well. Keep in mind that everything you source from your router comes FROM the primary IP address (IP Source). So that may lead to some issues of adjacency.
Debug ip packet may help see this behavior, but honestly, just change what IP is your primary. HTH, Scott Morris, CCIE4 (R&S/ISP-Dial/Security/Service Provider) #4713, JNCIE #153, CISSP, et al.

I was trying to advertise a secondary ip address over OSPF but it was not possible. I read on a Cisco Doc that an adjacency between routers using a Secondary ip is not possible but it did not mention about advertising secondary ip subnets. Does anybody have some feedback about this?
