Of course it's not something you should generalise about all people or
all traffic from certain countries. But it's obvious that there are some
countries which seem to care almost not at all about abuse or maybe even
are sources for planned hack-attempts. And at least some large ISPs
there seem to do nothing for their reputation or the reputation of their
country.


Kind regards,
 Stefan

Do you have data on '100% of the traffic' being bad?

I happen to have a large Chinese clientbase, and this is not the case on
my network.

Some may say this is harsh but is the network contacts refuse to
co-operate with abuse and 100% of the traffic is bad then why not

We're wondering if anyone has experience with such a setup?
Cisco have a feature called BGP-SD (BGP Selective Download).

With BGP-SD, you can hold millions of entries in RAM, but decide what
gets downloaded into the FIB. By doing this, you can still export a full
BGP table to customers directly connected to your 6500, and only have a
0/0 + ::/0 (and some more customer routes) in the FIB to do forwarding
to a bigger box.

BGP-SD started shipping in IOS XE, but I now understand that the feature
is on anything running IOS 15.

This would be my recommendation.
