Policies against NIMDA problems.

Hi everyone,

I've implemented policy based routing to figth against NIMDA; to apply theese policies on Cisco 7500

with VIP2-50 I nedeed to use Cisco IOS 12.1(7)E;

the policies provide the matching of the strings of the URL on port 80, the setting of dscp of the ip packet of the strings recognized to be dangerous, the dropping of the packets marked with route map or ACL.

The routers experienced VIP crashes and the packets were passing through them without being marked or dropped;

has someone any workaround about theese problems?

Any suggestion would be appreciated.
