Yes. There are extra licenses for L3 VPN (and insanely expensive), but basic IPv4/IPv6/MPLS is all in the basic IOS XR you buy with it. For a BGP edge router with "12x 10GE interfaces are sufficient for the foreseeable future" it's a very nice box. Very fast and very good BGP implementation, very robust altogether. There are caveats - upgrading IOS XR is very time consuming, so do not make this your single link to the world - the configuration is sufficiently different from IOS (especially the BGP policy language) that it will take a few days to get yourself sorted out. There are good intro pages into XR on the web, though. I think I've learned quite a lot from this blog: https://fryguy.net/ (now combined into https://fryguy.net/2012/10/19/ios-xr-workbook/) - single RSP - we've never had one fail on us, but of course, RAM can go bad, flash can go bad, etc. - so "do not make this your single link to the world" - dual PSUs, though :-) - it will not do everything an ASR1k can do - for example, no L2TP termination, limited support for ACLs on SVIs, no IPSEC tunnels, maybe more. So verify closely what features you need. gert -- "If was one thing all people took for granted, was conviction that if you feed honest figures into a computer, honest figures come out.
