How do you say "deny anything longer than /24?"
Is it:
deny ip 0.0.0.0 0.0.0.255 255.255.255.0 0.0.0.255
(sorry this bit fields get confusing, so I prefer prefix-lists..)
On a "bgp neighbor", what is used first, the "prefix-list", the
"distribute-list", or the "filter-list" - if route-map's are not in use?
And, how is it possible to permit a prefix ONLY if it matches a certain AS
path; for example, permit (203.176.8.0/24 AND _9442$). This is because I
want to send announcements to a peering point only if I heard the route
directly from a customer. Or can this only be done by denying the undesired
as-paths?
Thanks.
