Masood,
Yes you can if you use NAT to make your primary IP look as secondary to the
OSPF neighbor.
Is that what you are trying to achieve?

Subject: [c-nsp] OSPF on Secondary IP addresses.
Can OSPF establish as neighbors on secondary addresses? Do not have any
luck
unless the OSPF network interface is primary. Any ideas why and how do we
go
around this?
What if a ROUTERA is connected to a wireless bridge which is serving
multiple sites . Or there can be many other situation when you need to
build
adjacency on secondary IP address instead of primary IP.
Oops I can't find any parameter (when I configure secondary address on
Cisco
Router) like preferred/primary . thanks to juniper guys for providing it
;)

Thanks in advance.
