It'd be nice if this information came from one of the entities named above. Here's a refinement for our part.
GTE does not impose mandatory source address filtering via access-lists on customers' CPE routers. However, we have recently implemented Cisco's "ip verify unicast reverse-path".
I think perhaps we have an acronym collision here. I read Scott's comment to mean "Customer Premises Equipment", since that was the only parsing that didn't introduce a conflict.
However, I read Tony's reply as "Customer Provided Equipment", since that's my usual parsing of that acronym.
In this case, it makes quite a difference. Clarification?
Better: why not, Tony?
My meaning, and the one in common use around GTE Internetworking, is "Customer Premises Equipment" which can be supplied by us or the customer. The phrase "customers' CPE" above, would probably have been a tad clearer as just "CPE", especially since most CPE that we manage are in fact supplied and owned by us. Many customers choose to supply and manage their own CPE which means filtering or lack thereof is up to them. Clear? Tony
