Quick correct, they are extended access-lists
Genuity - first class provider, I would recommend them
What transit provider doesnt use prefixes? Do you think they're mad enough
to accept anything you send them?
And yes, they update the filter within minutes of you confirming the
request with them .. I have suggested they could build the filters from RR
but a quick email isnt the end of the world i guess..
It's a PITA when you sell transit your selv, and build your own filters
based on the IRR's.
We have been a happy Genuity customer for years, but are seriously
considering cancelling our connection to them, as it's too much work to
manually get the prefix lists updated.
