Which two changes must be made to migrate from DMVPN Phase 2 to Phase 3 when EIGRP is configured? (Choose two )
A. Disable EIGRP next-hop-self on the hub.
B. Enable EIGRP next-hop-self on the hub.
C. Add NHRP shortcuts on the hub.
D. Add NHRP redirects on the hub.
E. Add NHRP redirects on the spoke.
But the A is in phase 2!!!!
B is wrong because you don’t enable EIGRP, you Disable EIGRP.
No guys.
On the hub
interface Tunnel0
ip address 172.16.0.1 255.255.255.0
no ip next-hop-self eigrp 123
no ip split-horizon eigrp 123
ip nhrp authentication cisco
ip nhrp map multicast dynamic
ip nhrp network-id 1
ip nhrp redirect
so A and D is right
This is phase 3:
The following is an example of configuring DMVPN phase 3 on hub for summary map .
interface Tunnel0
ip address 15.0.0.1 255.255.255.0
no ip redirects
no ip split-horizon eigrp 2
ip nhrp authentication cisco123
ip nhrp network-id 23
ip nhrp redirect
ip summary-address eigrp 2 190.0.0.0 255.255.252.0
ip summary-address eigrp 2 201.0.0.0 255.255.252.0
tunnel source GigabitEthernet1/0/0
tunnel mode gre multipoint
tunnel key 6
end

So B and D are correct (when migrating from phase 2 to phase 3)
Yes Tomku, you are right
Correct answer is B & D
