Hi Collin Clark,
Thanks again for your reply. I have already serached for the same. But I couldn't find the commands
(in IOS XR 4.2) for applying service policy in control plane. Instead of that I got management plane protection and LPTS (Local packet transport sytsem) configurations in IOS 4.2 XR .But I need to know how to protect control plane of ASR 9000 using ACL/Routemap. I hope you can find the solution for the same. I am expecting your precious response.
