Hey Guys.
I have a 3 spokes right now and two hubs. The other day I rebooted one of the hubs and noticed that I had lost the tunnels to all of my spokes. I thought they would continue routing through the head end that was still up but that wasn't the case. Any ideas (see spoke config below)
interface Tunnel10
ip address x.x.x.x x.x.x.x
no ip redirects
ip mtu 1400
ip nhrp authentication abc123
ip nhrp map multicast x.x.x.x
ip nhrp map multicast x.x.x.x
ip nhrp map x.x.x.12 x.x.x.x
ip nhrp map x.x.x.13 x.x.x.x
ip nhrp network-id 200
ip nhrp nhs x.x.x.12
ip nhrp nhs x.x.x.13
ip tcp adjust-mss 1360
no ip split-horizon eigrp 100
tunnel source Fastethernet4
tunnel mode gre multipoint
tunnel key 1234
tunnel protection ipsec profile spokes

B Rockburn,
Are the spokes normally sending/receiving traffic via the hub that you rebooted, and you was expecting the secondary hub to takeover?

Hello Brent,
you should provide also the configuration of the two hubs, of the eigrp routing processes and the isakmp config ( focus on isakmp keepalive settings)
you have two hubs in the same DMVPN cloud it is important to daisy chain the NHRP configurations on the two hubs so that each sees the other as an NHRP server
Hope to help

Thanks I didn't have them pointing to eachother so that probably didn't help.
I'll try it out and let you know.
