Hi Guys.
We're deploying SDWAN in a customer who already has two ISPs connected in his hub, and talking BGP ECMP with them, using his public ASN and his own prefixes.
According to documentation, the SDWAN plugin requires the same BGP Router ID and ASN when declaring the hub in devices, but it won't allow to use the public ASN here.
So, my question is, do you need to create another VR in order to run a separate BGP process for the SDWAN side of things? Or there's a workaround to directly use the public ASN?. The closest scenario I could find is this one, https://docs.paloaltonetworks.com/sd-wan/3-0/sd-wan-admin/configure-sd-wan/configure-multi-vr-on-sd-.... The main difference is I wouldn't need a VR2, but I'm strugging to understand what interfaces need to be attached to VR1, and how the traffic needs to be forwarded between VRs. If that's the case, I would need to set up and maintain a lot of static routes there right?
Many Thanks.
