Just sitting around eating some chicken, catching up on my e-mail. I see in
the Tony Bates CIDR report to the NANOG list there is a reference to
"interesting aggregations".
http://www.employees.org/~tbates/cidr-report.html#Aggs
Thought some excerpts might make an interesting challenge. To whit, come up
with the appropriate summarization for the following routes that currently
appear in the "global internet BGP table"
These are things that caught my eye while browsing the report. I have not
tried to summarize them myself as yet.
How about it? Take a stab and publish your results? Have some fun?
