In DMVPN Phase 3, for the hub-and-spoke topology to support spoke-to-spoke communication, the hub must have the 'ip nhrp redirect' command enabled. This command allows the hub to inform the spokes about the ability to create a direct tunnel between them. Option A includes this command along with other necessary configurations like 'ip nhrp authentication', 'ip nhrp map multicast dynamic', 'ip nhrp network-id 1', and 'ip nhrp holdtime 300', which aligns with the requirements for setting up the DMVPN Phase 3 hub. Therefore, Option A is the correct configuration for the R6 router (hub).
Only valid configuration on the Hub is "A". https://ine.com/blog/2008-08-02-dmvpn-explained
Redirect is required on the hub
redirect on hub. shortcut command on spokes. DMVPN3
A is correct
Is it not required to add the command “tunnel mode gre multipoint “ on the hub router
