[c-nsp] vlan across a routed link

[teklay gebremichael]

i work in a university which has three campuses. on each campuse, there is one cisco 6509 switch as a core switch. all other switches (L2) are in vtp client except the core switches. the campuses are connected with a routed link. so, one campuse, has 10.128.0.0/16 subnet and the others have a subnet of 10.129.0.0/16 and 10.130.0.0/16. rip v2 is used on the intercampuse links to advertise individaul vlans.

here is my problem.

i'm asked to create a vlan with a subnet id of 192.168.1.0/24. but computers in this vlan are located in the 10.128.0.0/16 campuse and 10.130.0.0/16 campuse.the link between the 10.128.0.0/16 and 10.130.0.0/16 is not trunk it is routed with ip address.
so can any body suggest me how to implement such senario which allows one vlan (in this case 192.168.1.0/24) to be visible from the two campuses? i.e to propage that specific valn across a routed link not a trunk link.
thanks
