I need to change my DMVPN key chain keys because the accept-lifetime and send-lifetime timers have expired without taking down my remote sites. Can anyone send me a sample of how I can accomplish this? I have redundant core routers with tunnel 1 on rtr-a and tunnel 11 on rtr-b and I realize one tunnel will be down during the update. I have already ensured that all locations have both tunnels active. I am attaching a markup of my current config on rtr-a and rtr-b:
