We are looking into moving from out 7200 to ASR9K as our edge router. I have few doubts about this platform.
1- Does the ASR9K support NATing natively? (Cisco IOS XR IP/MPLS Core Software 3DES)
2- Does it support NBAR or any other replacement service to stop P2P and do inspection?
3- QoS is also done on the edge, we do some rate-limiting and shaping, does it support UBRL (user-baed rate-limiting)?
Finally, would you use it to replace your 7200VXR router?
I value your comments and questions.
