try using tunnel destination of "loopback0" instead of using the ip 
address of the interface.

EIGRP_over 2-Tunnels, complains " not on common subnet".
 Gurus, 
  I have a simple 2 routers over a serial link.
  i create 2 Tunnels between them , if i keep the "tunnel Source" and 
"tunnel dest" to exactly same as Loopback 0 , Eigrp complains regarding 
"neigh not on common subnet" if i keep then diff , as in 2 diff 
sources/dests , its works.
  I know its got to do with primary IP add space, cant feel the real pulse 
here.
 config on R1:
 interface Loopback0 
 ip address 1.1.1.1 255.255.255.255
 no ip directed-broadcast
 no clns route-cache
!
interface Tunnel0
 ip address 128.1.1.2 255.0.0.0
 no ip directed-broadcast
 no clns route-cache
 tunnel source Loopback0
 tunnel destination 2.2.2.2
!
interface Tunnel1
 ip address 129.1.1.100 255.0.0.0
 no ip directed-broadcast
 no clns route-cache
 tunnel source Loopback0
 tunnel destination 2.2.2.2
!
interface Serial0/0
 ip address 172.16.1.100 255.255.0.0
 no ip directed-broadcast
 no clns route-cache
 same config at R2 too.
 Shukla.
