Tassos,

Besides what you and Ole discussed, I have some comments below.

First, if any text is added, the text has to be each LAN interface specific.  The home has a router with a wireless link.  The wireless link also sends out an RA and such a link is likely to have a different MTU than the wired LAN link in the home.  Now that transition tech has been added to the document, with tunnels there is the DF (Don't Fragment) bit.  See RFC 4449.  For now, I think the complexity of the routed home for MTU and tunnels is best handled manually.  With manual configuration, some extra knobs could be provided.  As you said a host can also set the MTU, and thus we may skip adding MTU related text to the LAN section.   Please also note that the rfc6204bis is merely adding two IP transition techs in 6rd and DS-Lite and IP Transition tech coexistence to RFC 6204 and thus other changes to the text form RFC6204 will only be made for editorial errors (such as replacing ICMP with ICMPv6) or if a Show Stopper problem is discovered in RFC 6204.  

Regards,

Hemant
