SD-WAN transport-side BGP

cisco sd-wan transport-side BGP and DIA NAT

The majority of Cisco SD-WAN guides and posts I have found use static routing rather than routing protocols on the transport-side. Static routes are all very well for SD-WAN tunnel traffic but I was wanting to understand how you equate for DIA traffic in a more real-life situation where address ranges are advertised via BGP.

SD-WAN service-side MPLS VPN

using bgp mpls vpn for service-side cisco sd-wan connections

This post goes through how to configure MPLS VPN on the service-side of a Cisco SD-WAN edge device, so the south-side towards non-SD-WAN devices. What I am trying to achieve is to advertise the differing SD-WAN VPN (VRF, why Cisco have to call these VPNs beats me) prefixes to a core switch (using a ASR in the lab) directly connected to the SD-WAN router. This could be accomplished using per-VRF interfaces (or sub-interfaces) and BGP peerings, but a neater solution is to pass all the routing information over one the BGP MPLS VPNv4 peering.
