@WillieHowe@Ubiquiti I've used a vdsl2 flavour of the same concept in several sdwan projects I've run recently. Big fan of this over a separate modem that floats around in the rack
@danieldibswe Ospf with ip numbered links, and ospfv3 with ipv6 link local addresses. Leaning towards v6 underlays these days. I'm not building anything massive, but I fail to see the requirement for bgp in the underlay.
