The reason we (as an operator) can’t use BCP-38 is the vendor hardware can’t
do it at line-rate and the performance hit is too much to sustain.
That seems worth a bit more discussion. I'd always naively assumed that BCP38
was
scalable since all it appears to need is a prefix match, and routers are very
good at matching prefixes; it's just that they don't normally match the source
prefix. Could some router-vendor person comment on this?
There's another issue here, though. BCP-38 and uRPF are also a potential cause
of
connectivity problems:
