SDWAN with DR design

[VincentZHU]

hi,Expert:

I am deploying MX SDWAN with Active-Active DR as following topu

          DC1  Hub  ------

            |                        \ 

            |                  INTERNET   --- Spoke  

            |                        /                   

          DC2 Hub  ------

Spoke accesses DC1_subnet via DC1 as primary Hub and DC2 as backup Hub,vice versa, i.e access DC2_subnet via DC2 as primary Hub and DC1 as backup Hub

When I set Hub priority on spoke,seems it can't set Hub priority per destination subnet. I also have no way to config iBGP local preference with route-map on Hub.

How can I implement my target?

Thanks.

I think that you aren't able to achieve that. Take a look at this.

Maybe you can achieve your goal with per‑destination SD‑WAN VPN traffic preferences.

This document talks about how BGP is used in Meraki.  Take a look at the "weight" parameter.  Perhaps you could use MED.

Note that you need to be using MX 19.1.4 to get the good stuff.
