The vEdge and cEdge product line up both have smaller branch units that appear to be built for a single provider.

However, the Viptela/Cisco SD-WAN solution does not appear to accommodate a single transport in its failover design.
Has anyone found Cisco guides on SD-WAN failover considerations for a single transport office? The issue to solve for would not be the local transport (if that's not obvious!) but rather an problem (latency/jitter/loss) closer to a remote datacenter.
Common branch deployments in the CIsco SD-WAN Design Guide all appear to show two transports (mpls/inet, mpls/lte , inet/lte) and while there is a mention of 'scaling traffic to the same transport' there is very little detail on it.
