It is only a requirement for SLAAC, yes, but it's also recommended quite strongly in various RFCs and other docs from the IETF. The IETF wants /64's everywhere (which IMHO is quite wasteful, but ...) http://tools.ietf.org/html/rfc4291#section-2.5.1 http://tools.ietf.org/html/rfc3627 > If you're doing static IPv6 address assignments and don't > need SLAAC, then you can go for longer (or non-typical) > prefix lengths. > > I use /112's where I don't need SLAAC.

I'm not sure I trust everything else to properly adhere to what _should_ work... :-) Jim _______________________________________________ List mailing list [email protected] http://lists.pfsense.org/mailman/listinfo/list
