So far, Cisco's gear is the only IPv6 routers I've messed with. And they will not let you set an interface to anything smaller than a /64. Loopbacks have slightly different rules, but in my case (IPv6 tunnels) that fact hasn't proven very useful.
My 12.0(S), 12.4, and IOS-XR boxes are operating quite well with /112's and /127's on GigE interfaces to each other, on GSR's, 7300's, and 7200's. We also use /128's on loopbacks. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
