bgp customers.
Agreed, but in this case it's just a matter of BCP. My provider takes a default from Telus. If I wanted to a default from that provider (who is already taking a default from Telus), should best practice be such that the default is sourced from my provider's AS, not Telus'?

2) filter it
Absolutely. In this case, I hadn't dropped my filters in yet so it stuck out like a sore thumb.

split AS, it may be of value to have default route to hold
things together..

Yup, been there, done that too...
