Re: SAILing LAPs

[Alexandre Petrescu <[e-mail]>]

I find this Internet Draft to be a little help in the right direction - 
encouraging.

We know BSD implements various lengths for IIDs, including 64 and 63, 
for SLAAC.

We also know linux kernel does not support any other length than 64.  An 
effort of a kernel programmer of approximately 3 days could not make 
linux kernel accept plen 65 and self-configure an address.  I am still 
looking for someone for help.

Alternatively, this IoT Router's Qualcomm modem does not _want_ to allow 
DHCPv6 Prefix Delegation outgoing UDP port number 547.  They are what 
can be qualified as stubborn :-)

For me, this is kind of an urgent matter.  We build a prototype onboard 
IoT Router to connect a car on cellular network.  It does 64share, and 
further down the car network there is L2 bridging too.  However, deeper 
inside there are further IP subnets - webcam and others.  IPv6 can not 
reach them.

If by end of July I dont get this 65plen and 63IIDlen working then my 
onboard IPv6 design definitely has a conceptual flaw.

I find this Internet Draft to be a little help in the right direction - 
encouraging.
