GetVPN over DMVPN Phase3, Multicast Rekey on mGRE Tunnel

[turhanozyer]

Hello Guys,

Have you got a working config on GET VPN rekeying using multicast over DMVPN Phase 3 network on mGRE Tunnel. (Not using the multicast service on

SP network.)

Thanks,

Unfortunately there is no exact Cisco document on your requirement but I guess the below link is what you are looking for.

Hello Rahul,

I know this link. It's about a Phase1 topology. My problem is the PIM communication between Spokes and Regional Hubs (Not the HQ Hub) in DMVPN Phase3. I couldn't get PIM updates inside the tunnel from Regional Hubs.

Thank you very much,

Regards,

I have a working config right now.  I did it. GetVPN over DMVPN Phase3 with Sparse-Mode Multicast Rekey inside the mGRE tunnel.
