Haha, I'm just hoping the answer isn't something silly like 'enable the tunnel interface with the no shutdown command'. That would be like the IT equivalent of 'have you tried turning it off and on again?'

Good point, Charlesetta. I'd start with option A, but I'd also look into options B and C just to be thorough. Can't hurt to cover all the bases, right?

Yeah, I agree. Configuring the same IKE version on both the spoke and hub seems like the logical first step. But we should also check the ESP and GRE traffic, just in case there's an issue with the network devices between the routers.

Hmm, this question seems tricky. I'm guessing the issue is with the IKE version, since the question specifically mentions IKEv1. Maybe we should try option A first and see if that works.
