Configuring Secondary IP address in LAN Sub Interface

Hi,

I have a setup, in which two servers need to communicate with a Router in a VLAN Segment. The challenge is that we have created a sub interface in the LAN interface of the Router with encapsulation dot1q 310 with IP address 192.168.10.1/24. The servers are in a different IP range (10.250.14.9 and 10). The Router connects to Gig 1/4 in the core switch (managed by a 3rd party) and the servers connect to Gig 1/2 and Gig 1/3 in the same core switch which are assigned to VLAN 310.

Now if I configure a secondary IP address in the LAN sub interface of the Router with IP 10.250.14.1, can I establish connectivity between the Servers and Routers?

Also, can I advertise the secondary IP subnet in BGP, to the WAN?

Thanks for your time.

Regards

Gnanavel.
