Did you see the switch logs. It might be reporting the native vlan mismatch error. This is not a recommended config as per the CDP goes, due to which it might have been reporting the CDP native vlan mismatch and wasnt generating the CDP info for the neighbor.
I didn't see mismatch error in the switch. You know what, we have exactly same pair on other location with exact same configurations on both ends, except the router sides are configured sub interface for "router in a stick". and they don't have the problem find each other with CDP.
My coworker told me it is because the sub interface is configured as 1q trunk in router side, it'll send the cdp traffic, whereas the problematic one only has one side trunked. the other side won't send.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
