The existing implementation of draft-mouton-mif-dhcpv6-drlo-00 does not handle renewal. We're facing too many options about it: should it RENEW? Should it send an RS as well? This is up to debate. But it is related only to the default route, not the other routes. Remark the debate comes from the lifetime of ND as well. >> What do you mean by "use case" so I can better detail how this >> default route option is necessary, thanks. > > The 3G+ scenario is the first use case you've presented, so thanks > for that. > > If interface names are in fact required, that's interesting.

Is there an RFC > or draft that documents how this works? Just puts it on the pipe, but needs to know on which pipe when several interfaces are available. I would like to add further: - we do not try to suggest problems for others to solve, but would like to participate in the solution space. - in the use case of use Mobile IP, the default route on a 3G+ terminal points actually to a virtual interface tunnel name, and not to a real interface. (the real interface is used as target of a host-specific route towards the Mobile IP home agent.) - in the case of using a v6-v4 transition method, the default IPv6 route points to a virtual interface as well, and not to a real interface. In this case as well, the default route communicated by DHCPv6 to a multiply-interfaced Client needs potentially much more than simply dst address of the default router. Alex >
