But if that AS is a stub, you still can't use their up stream providers to get data out to the rest of the world. It still wouldn't even function as an "alternative path" it would only function for the subnets which that AS owns. Paul Stewart wrote:
Thanks - I believe the wording meant was "alternative path" versus connection... in other words if an AS has issues with one or more upstream providers for whatever reason, you have good chances the peering connection will remain in better shape (not always granted, but good odds)....

It would only be a redundant connection if the AS your peering with is a transit AS. The AS that I work with is a stub AS and can not function as a fully redundant link.
Just something to watch out for.

I can think of some but looking to develop a concrete list of
appealing
reasons etc. such as:
-control over routing between networks -security aspect (being able to filter/verify routes to some degree) -latency/performance
I'm surprised you didn't include "chance to pick up a redundant connection".
