I think the issue is that we might have a lot of Huawei routers deployed on the Internet with this code so in practical terms it's probably 12-18 months away to have all of them upgraded to a version where they will not drop prefixes with large BGP communities. This will leave networks that want to use large BGP communities with the choice of * using large and not becoming reachable from networks that use Huawei * OR not use large and reach the whole Internet I think a lot of network operators will choose the latter so in the end we'd be slowing down the implementation speed of large rather than punishing Huawei. Kind regards, Kristian.
