B/ When we can easily do:
"router bgp N
proxy-aggregate route-map Lazy-Types
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!
