My DMVPN worked fine yesterday. However the DMVPN didn't come in. I left it for 20 with no joy.
Once I did a clear crypto sa on the spoke the tunnel came up.
This seems like I'm missing something in my config.
Can someone advise?
Sorry my Spokes tunnel config is:
ip address 10.x.250.6 255.255.255.0
no ip redirects
ip mtu 1400
ip nhrp authentication password
ip nhrp map multicast dynamic
ip nhrp map multicast publicIP
ip nhrp map 10.x.250.1 publicIP
ip nhrp network-id aNumber
ip nhrp holdtime 360
ip nhrp nhs 10.x.250.1
zone-member security Zone-TunnelToHO
ip ospf network broadcast
tunnel source FastEthernet4
tunnel mode gre multipoint
tunnel key aNumber
tunnel protection ipsec profile protect-gre
I think it's going to be something in crypto config, either invalid SPI recovery (alhough it's not strictly speaking required) or DPD missing (considering what you described and how you recovered).
