OK I have three routers. R2 is connect to R1 and R1 connects to R3. I want to be able to to create a two tunnels on R1 that connects to R2 and R3. Created the tunnels, when I created the first one, everything was fine, but when I created the second tunnel I get the following message:
*Mar 1 00:30:05.803: IP-EIGRP(Default-IP-Routing-Table:90): Neighbor 192.168.1.2 not on common subnet for Tunnel1
The following are my configs
R1

service timestamps log datetime msec
