Failed due to major Issue on DMVPN SIM during the exam

[knighthawk]

I started to see ospf issues on only one of the tunnels. It was happening before I configured crypto isakmp policy.  I think it was r1 to r3.  The only task was to configure IPSEC over the tunnel.   The PC off of R1 could never ping the pc off of R3.  It made sense because the tunnel was bouncing.  Show dmvpn looked fine on both spokes.   The IPSEC configs were exactly the same on 3 devices.  The tunnel configs were exactly the same on all nodes.   I spent way too much time on this sim and failed the exam.  Anyone else see this issue.
