Hi Ole-san,
I have a question about MTU option in router advertisement. The draft says: > "A 6rd CE SHOULD advertise the 6rd Tunnel MTU, whether determined > automatically or configured directly, on the LAN side by setting the > MTU option in Router Advertisements [RFC4861] messages to the 6rd > Tunnel MTU." My understanding of the role of MTU option in RA is that if hosts are in configuration in which different media type are bridged, advertising mtu size all media supported. Does CPE should advertise the 6rd Tunnel MTU even 6rd tunnel does not bridged to CPE LAN side? --satoru On 2010/02/04, at 0:59, Ole Troan wrote: > hi, > > we've just posted an updated revision of the 6rd draft, which we > believe is ready for last call in the softwires and dhc working > groupsl. > > apart from cleaning up text the main changes are in the DHCP option, > which now includes a list of BR IPv4 addresses.
