two tunnels

I'm having some problems with setting up two GRE tunnels between two
routers. I create two tunnel interfaces with source Serial0 and destination
as the address of another router. I have EIGRP running on one of the tunnels
and IGRP on another of the tunnels. No networks would get advertised across.
Eigrp neighbor relationship wouldn't get installed. If I shut down one of
the tunnels, EIGRP (or IGRP) will start working. (Autonomous Systems are
different)

Is anyone aware why this wouldn't work? In reality GRE packets will have
source and destination the same for both of the tunnels. But then I would
think the destination router would unpack the actual IP packet with source
and destination of the real tunnel interfaces. ?
