There are definitely some horror[1] stories, yes. I realise that cost can be an issue, but if you're capable I'd look at literally anything else. I'm assuming that the requirements here are to provide IP/IPv6 connectivity to these circuits, possibly QoS and simple iACLs? Any 4-6 translation methods? Customer BGP? If so, then do not overlook buffering capability, software features, and the lifetime that you might very well expect those software features to be supported and/or developed. The most common go-to lines here will be from Cisco ASR920/ASR900 series/ASR1000 series, or one of the many Juniper MX devices. I'm sure Nokia have capable devices to do this, too, but I still don't see many smaller ISPs buying from them yet - if you can, it's an option. It's probable that if you're doing IPVPNs that you'll already have some of this gear in place? :) Just don't get tempted to whack a switch on the end of your NNI.[2] Regards, -- Tom [1] https://www.youtube.com/watch?v=R0INwMN6FFE (UKNOF #43, Manchester) [2] Been there, lost the sleep.
