As mentioned earlier, why make the core boxes do all of the work? Why not distribute the functionality out to the edge? Rather than using traditional switch gear at the edge, use smaller Linux boxes to handle all that complicated edge manipulation, and then keep your high bandwidth core boxes pushing packets only But I do ask:
Do you (the ISP) control the CPE (modem / ONT)? Could you push the VxLAN (or maybe MPLS) functionality all the way into it? This would have the added advantage of a (presumably) trusted device providing the identification back to your core equipment. Perhaps even minimal L3 routing w/ DHCP helper such that the customer saw the CPE as the default gateway. (Though this might burn a lot more IPs. This might not be an issue if you're using CGNAT.) -- Grant. . . . unix || die
