PFRv3 without DMVPN?? IS IT POSSIBLE??

Hi Experts,

 

We have a dual-hub architecture in our environment. Remote sites connect to the hubs with point-to-point GRE tunnels. We want to achieve intelligent routing based on latency, delay, jitter and utilization of the links. Seems cisco iwan can solve this but all iWAN scenarios i come accross all use a dmvpn type setup. Can PFRv3 solve this challenge for us even without DMVPN?

  • PFR does not require DMVPN. You just need 2 paths out - they can tunnels (GRE, mGRE, etc), or physical interface/subinterfaces. As long as your device has more than 1 way out of the site, you can leverage PFR to optimize outbound forwarding.

    IWAN uses DMVPN...this is what they have tested it with. The reasoning behind DMVPN is that you can run it ontop of any transport. But technically PFR does not require DMVPN.

  • Thanks Plucena, just to clarify. PFRv3 specifically simplifies the configurations as opposed to PFRv1/2. With the multiple tunnels at the hub site (about 300 tunnels), can the config still be simplified in this manner??

  • Just got a clarification from TAC.

     

    PFRv3 is not supported without DMVPN
