I am trying to determine if it is possible/supported to use PfRv3 only to load balance Internet bound traffic over two ISP links from a hub site. At present, there will be no DMVPN to branches. The primary use-case is to only load balance Internet traffic from what would be identified as the hub site in IWAN terminology. I have a lab configuration using 3 ASR 1001 routers with one MC and to BR routers. The domain is up and requirements are met and I can see load balancing attempting to kick in as I place load on one external interface but I get a message that there are "no channels yet for load balancing". I do not have any tunnel interfaces configured, aside from the auto-tunnel created by PfR.

It seems that PfRv3 may not be able to support this based on reading I've done and a similar question posted in 2015 at https://community.cisco.com/t5/routing/pfrv3-without-dmvpn/td-p/2738707. Has anyone attempted this or know if this is even possible?
