This gripe is kind of a personal one but I'm having trouble letting it go :) Whilst the config is similar to a traditional 7200 many features don't work or have been changed. See some notes I made here: https://null.53bits.co.uk/index.php?page=asr-ios-xr-lns-config We also had quite a few issues getting QoS to work as we would have like it, again some notes here: https://null.53bits.co.uk/index.php?page=adsl-and-lns-shaping-llq I think for either the ASR1K or ASR9K series you need to be using RADIUS with CoA, which is fine, that is common today, but we were a bit behind the times probably so that is/was another hurdle that has made the transition longer/harder than I would have liked. IOS-XE has been buggy for us specifically with the BNG/LNS feature set on ASR1Ks (I know we have had bugs on ASR920s for example, but we use them for a different purpose). We've had plenty of bugs on the ASR9K's too, but for the 1Ks pretty much all the bugs I have encountered were/are related to us using them as an LNS. I don't think (off the top of my head) I have hit any bugs on the ASR1K's for any of our "normal" feature set (MPLS L2 and L3 VPNs). I recommended the ASR9001 because it has 10G ports built in. We chose ASR1002-X's but if you want to go over 1Gbps of LNS traffic you need to either bundle some 1Gbps ports and the QoS on port-channels for PPPoL2TPoIPoMPLS is not good (nor for PPPoE), or use multiple layer 3 individual 1Gbps interfaces (the design I am settling on) or buy some 10G ports. If you can get away with an ASR9001-S then I think you might get more mileage (depending on your personal pricing lists etc). Many people are happily using the ASR1000s as BNGs, I would just recommend you heavy test all your different deployment scenarios. Also check out the cisco-bba list for subscriber/broadband specific topics.
