I am currently working with a DMVPN connection between my office and our headquarters.
When the Hub router at headquarters goes down, I have to reboot my router or go in and shut the tunnel down and then no shut to get it to come back alive.
I know this is probably a lifetime command or sa command that it needs.
My question is what configuration is best for this. When the tunnel goes down, I need it to begin trying to re-negotiate so that I do not have to reboot my router or issue the shut and no shut commands on the tunnel interface.
