Is this correct usage of Secondary IP [ALU]

Trying to figure out if I'm using Alcatel's Secondary IP on rvpls correctly.

Telecom device is connected to ALU L3 switch via trunk and VL728.

SVI/rvpls is created and assigned 10.48.196.109/30. Switches are running OSPF, telecom device has static routing (default GW to 10.48.196.109).

The device has IP 10.48.196.110 and everything works as expected.

*****

There is a new requirement to add Virtual IP to the device to separate OM. Virtual IP is created within the device as 10.48.105.18.

Now am I correct using Secondary IP on the switch SVI side to allow communication?

I can see OSPF advertises secondary subnet correctly and its GW .17 can be pinged, but not device's 10.48.105.18

Do I need anything else to make this click?

Thank you.
