PFRv3 LAB - Not-Available(Channel in Initial state)

I am currently testing PFRv3 in lab environment.

I have tried to make single HUB-MC with two other routers as MC-Borders. 

on the Spoke side Branch MC and Border are on the same router.

 

However, the PFRv3 channels cannot go both to RX state:

From DMVPN HUB which is being used as Border - TX channels goes to Available state to Spoke.

R1-hub1_1#sh domain pfr vrf intranet border parent-route
Border Parent Route Details:

Prot: BGP, Network: 172.18.255.246/32, Gateway: 172.16.254.2, Interface: Tunnel0, Ref count: 1
R1-hub1_1#

 

But from Spoke Border to DMVPN HUB Border - TX is unreachable:

R2-spoke#sh domain pfr border channels parent-route
Border Channel Parent Route Details:

I consider the problem is that on Spoke router the next-hop is 0.0.0.0

Channel next_hop : 0.0.0.0

My main question is why it is so? and how can I change it to point to proper next-hop?

 

Here below the routing table for Spoke2 is shown:

Hello,

 

it is hard to tell from what you posted if even the DMVPN is up and connected. Do you have the key chain configured correctly for PfR ?

Post the full running configurations of your hub and spoke...
