yes. Probably you are allowed "ip unnumbered addresses for the GRE
tunnel". You have to then be careful about active routing protocols which
will broadcast/multicast over this tunnel. You might need to declare the
tunnel interface as passive.
You also most likely will need a static mroute.
Watch for any RFP failures.
i.e.
*Mar 1 00:31:41.631: IP(0): s=192.168.5.5 (Tunnel1) d=228.22.22.22 id=30,
ttl=253, prot=1, len=100(100), not RPF interface
