bridging 172 networks ?

A certain host dhcp server (dhcp3d) has been serving up IPs in the 
172.16 range to an internal network.

This server's upstream has now changed to, also, a 172.16 based network

Thus one nic is given a address by the upstream server,
the second nic is handing out leases in the 1.2 to 1.254 range.

Does one of these networks need to switch to 192 or 10, or can they both 
be on 172?

If so, what is the best solution to preventing an IP conflict?

Hoping this question is neither too simple nor too complicated but just 

with TIA,
