It’s hard to find Cisco-information about IS-IS support but it doesn’t seem to be supported. See the community-link below.
This question is similar to Q161.
Several routing protocols can be used in a DMVPN design, including:
Enhanced Interior Gateway Protocol (EIGRP)
Open Shortest Path First (OSPF)
Routing Information Protocol version 2 (RIPv2)
Border Gateway Protocol (BGP)
On-Demand Routing (ODR)
Correct Answer is ACD – RIP2 is not a protocol RIPV2 is
Pay attention EIGRP, RIPv2, OSPF and BGP all support DVVPN
DMVPN not DVVPN sorry
I think ABCD is correct.
