Router Choice

Hello fellow nanogers, I am a long time user of Cisco gear and currently evaluating an alternative for my network expansion. currently the one that looks like it will be able to do the job iare Alcatel-Lucent 7710/7750 service routers. I am looking for real life experience of those who have used it and what I may need to watch out for (if anything) I have seen in some of their documentation features like Non-stop Services (NSS) and Non-stop Routing (NSR). are these features real world deployable. oh, just to add I want to use the routers as P routers in my IP/MPLS core Regards -- Raymond Macharia
