Glad to see your local policies could be different. This will at least
allow
for your clients to load-balance.
What about a client doing load-balacing between multiple providers? Would
you,
for example, carry longer prefixes from your clients one or multiple peers
away?
It boils down to what do you consider local vs global. You'd probably have
to
put a limit on the AS path length of the longer prefixes.
I guess this all can be negotiated with transit and peers, but it's good
to share views on this so that we end up with consistent policies
wherever that's possible.
