Answer: BC

Explanation:

DMV PN Phase III is same as Phase 2 but removes some restrictions and complexities of Phase 2.

Also allows greater variety of DM VPN network designs we use:

+ ip nhrp redirect in hub: tells the initiator spoke to look for a better path to the destination spoke than through the Hub. Upon receiving the NHRP redirect message the spokes communicate with each other over the hub and they have their NHRP replies for the NHRP Resolution Requests that they sent out.

+ip nhrp shortcut in spokes: overwrite the CEF table on the spoke. It basically overrides the next-hop value for a remote spoke network from the default initial hub tunnel IP address to the NHRP

resolved remote spoke tunnel IP address)
