I am currently working on setting up ERLs at our locations. We have two ISPs at each site, so I am trying to create 2 tunnels to each of our 2 core devices (Vyattas). On the Vyatta I am able to create 2 GRE tunnels with the same "local-ip" (Vyatta WAN IP) without issue. When I create the 2nd tunnel on the ERL with the same "local-ip" (ERL WAN IP), I get the following error and have not found any others trying this type of setup:
[ interfaces tunnel tun5 ]
Cannot find device "tun5"
interfaces tunnel tun5: error setting tunnel interface active
Cannot get device feature names: No such device
Any feedback is appreciated!
