as-path padding
First, policy?
- Private interconnects - pad no times
- Regionality of traffic - pad four times x-country
- Pennsauken over MAE-East - pad once; twice
- Public Exchanges - twice at MAE-West
- Transit pipes, above.net first - pad three
Problem - can’t pad easily going cross-country.
But we can do the rest.
- Problem - lots of route-maps and typing.
Why? Can’t prepend our own AS inside network, so must have separate roue-map per session.
