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

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

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

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:

B*    0.0.0.0/0 [20/0] via 10.25.1.2, 00:16:48

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

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...
