Hi,
I have a 2 spoke to hub DMVPN setup, we are working on getting one spoke setup with 2 ISP's on 2 physical interfaces. I have everything working except the backup tunnel will not connect. I have researched this and followed some examples, but can't get it to work. The back up tunnel seem to flop.
Here are the config for the hub and spoke.
Thanks,
M
