Re: [dhcwg] [Int-dir] Intdir early review of draft-ietf-dhc-rfc3315bis-10

Hi Bernie,

My pleasure as always.

And, for those particular cases, the client should probably retransmit "forever" at a hopefully low rate (SOL_MAX_RT and INF_MAX_RT are 3600 seconds*) to locate a  DHCP server. This of course depends on the RA M & O bits (indicating a DHCP server is available) or the manual configuration of the client (to explicitly run DHCP).

Then depending on this information, it is up to you to see if there is
a need of an affordable better description than the current text.

Cheers,
