so what you're saying is that if you don't specify the ge xx le xx, it
means that you are specifying a minimum mask length ?
seems odd, but i'll believe it...
basically that would mean that
ip prefix-list 10 permit 192.168.0.0/24
is the same as
ip prefix-list 10 permit 192.168.0.0/24 le 32
??
on this topic, do people remember the days before prefix-lists, where you
HAD to use extended ip access lists for route filtering, and the
"destination address/mask" of the extended acl referred to the mask of the
route ?
it was never any fun to see:
access-list 100 permit 192.160.0.0 0.0.0.255 255.255.255.0 0.0.0.255
cheers,
-marc.
