As part of this effort, if anyone is aware of ISPs who intentionally de-aggregate routes and could contact me to share some of the reasoning and their methodologies behind this, I would greatly appreciate it.
Explicit de-aggregation, in this case, is taking an existing announcement and creating more specific announcements from it. For example, taking 10/8 and creating (where it didn't exist before) 10/9 and 10.128/9. The leaking of more specific routes that actually exist in your network is more a case of failing to aggregate, even if the assiged internal networks are a result of taking your assigned block and breaking it into several subnets. Thanks for all the responses thus far. -- Jeff Haas NextHop Technologies
