Dear NetPro!
I would like to route some prefix to null0 in a Cisco ASA 5540 perimeter firewall. I have found no information about this virtual interface in ASA. Does anybody have any experience how to configre and implement these static routes?
Thanks in advance!

AS far as i know the ASA does not support a Null0 interface in the same way IOS routers do.
The solution i have used is to point the routes to the nearest next-hop router under your control and then Null0 them on that router.

There is no such thing on ASA. Why not simply deny the traffic in your access-list(s) ?
