changes refers to was this:
The default behavior of exterior routing protocol sessions between administrative routing regions must be to ignore receipt of and not advertise prefixes in the FC00::/7 block. A network operator may specifically configure prefixes longer than FC00::/7 for inter-site communication.
If BGP is being used at the site border with an ISP, the default BGP configuration must filter out any Local IPv6 address prefixes, both incoming and outgoing.
This was discussed (without a resolution) in November: http://www1.ietf.org/mail-archive/web/ipv6/current/msg03898.html
This 'default behaviour must be to ignore' seems rather inpractical to implement from vendor's perspective (unless you create a special knob 'allow-ula' applicable to eBGP). Therefore I'm doubtful whether it gets implemented..
I think this was responded to:
http://www1.ietf.org/mail-archive/web/ipv6/current/msg03901.html
This is mean as operational guidelines. We are not precluding a vendor from implementing such a "knob", but do not require it. This is based on discussion with the routing ADs as part of their review of the document.
