An engineer is designing a DMVPN network where OSPF has been chosen as the routing protocol. A spoke-to-spoke data propagation model must be set up. Which two design considerations must be taken into account? (Choose two.)
A.
The hub should be the DR by changing the priority of the spokes to 0
B.
The hub should be set as the DR by specifying the priority to 255
C.
The network type on all sites should be point-to-multipoint
D.
The network type should be point-to-multipoint for the hub and point-to-point for the spokes
E.
Configure all the sites as network type broadcast
Checked the link and based on this it's AE.
Hub, Spoke1 & Spoke2
(config)#interface Tunnel 0
(config-if)#ip ospf network broadcast
Spoke1 & Spoke2
(config)#interface Tunnel 0
(config-if)#ip ospf priority 0
Answer is A/C: These considerations ensure that the hub is the designated router (DR) for OSPF, which simplifies the routing process in a DMVPN environment. Setting the network type to point-to-multipoint on all sites helps in efficiently managing OSPF neighbor relationships and routing updates, facilitating direct communication between spokes.
