my company does it (not by my choice) - my downstreams do it regularly (mostly because they don't understand how/why to do something different) i have been told that it is that way for 'backup' purposes (they announce one or two /2[456]s to me with about 15 as prepends, and announce their entire /20, plus all of their longer prefixes, to another provider) they also told me that it will not be changed...apparently, as routers get more powerful and memory gets 'cheaper', they feel that it is not their responsibility to help maintain global routing table sizes Jack Bates <jbates@brightok.net> wrote:

Thoughts?
I was curious how much of the de-aggregation was due to multi-homed companies requiring the longer prefixes. Are there companies that actually announce their smaller routes despite controlling the shorter prefix? What would be the benefit of doing so?
