Most of these affect RFC 6204 CE-compliance, some are convenience changes. Feel free to merge and test CeroWrt. * Detect and delegate IPv6-specific MTU from upstream interfaces (e.g. tunnels, pppoe, etc.) and propagate them to downstream interfaces (supporting cases where IPv4-MTU and IPv6-MTU differ, e.g. 6in4, 6rd, 6to4, ...) * Add a default null-route for delegated prefixes (CE-requirement WPD-6) This fixes routing loops in case packets with a destination within an unused / unassigned part of a delegated prefix are received. * Added support for site-borders (interfaces which ULA-traffic might not cross) as specified in CE-requirement ULA-4 * Added support to override CE-requirement ULA-5 for NPT-setups (iirc not relevant if dnsmasq is used, as it does not follow ULA-5). Documentation on http://wiki.openwrt.org/doc/uci/network6 has been updated. Btw. Simon Kelley released 2.66-test4 which fixes some bugs related to stateful DHCPv6 and should make it usable finally. Also the new MTU-propagation mentioned above is now supported by dnsmasq as well. I haven't tested it myself yet but you can try if you are brave. I will try to make a table about the RFC requirements for Customer Edge (CE)-Routers soon which sums up which requirements are fulfilled and which are still not implemented both for CeroWrt / OpenWrt with 6relayd and with dnsmasq as RA/DHCPv6-server. Cheers, Steven
