Under what scenarios do providers install egress ACLs which could say for eg. 1. Allow all IP traffic out on an interface foo if its coming from source IP x.x.x.x/y 2. Drop all other IP traffic out on this interface.
If you're an end node, it's BCP to block ingress from your own IP space, and block egress NOT from your IP space. If you're doing transit, it gets more complicated. Jeff
