| I may be misunderstanding, but does this (proposed) config statement
| automaticly suppress (aggregate) any prefixes that are exactly the
| same as another prefix except in the length? For example given
|
| 128.8.0.0/16
| 128.8.0.0/24
| 128.8.1.0/24
|
| the last two would not be propogated? That would be cool!
Right, essentially. This is particularly easy if all the
attributes are the same, notably the AS_Path.
In IOS there is already a pretty good set of tools to choose what
one proxy-aggregates -- and how -- that were developed several
years ago; a tool to choose when to apply a set of these would also
be useful.
One policy that I think would be useful would be: "Does the origin
AS announce more than N prefixes? If so, aggregate/drop more specifics
as follows..."
