Re: Last Call: 'Neighbor Discovery for IP version 6 (IPv6)' to Draft Standard (draft-ietf-ipv6-2461bis)

I agree that the issues mentioned in the draft draft-madanapalli-ipv6-periodic-rtr-advts-00.txt should not be blocking 2461bis, and should be moved forward. But I think the draft is applicable for certain category of networks (Cellular Networks) so it may not be a good idea to put the same inform

802.16 is point-to-multipoint connection oriented technology. There will be a seperate connection for each subscriber station from base station. A subsriber station cannot establish a direct connection to another subscriber station. The 802.16 connection just covers the last mile. So I am not sure

The flags are just hints, the host can always ignore them. If it is inappropriate to try to use DHCP when flags are zero, let it be so. Similarly if the flag(s) is (are) set, the host can always ignore. Otherwise we need to say that the M/O flags are triggers of DHCP. So we need to agree if the

Hi, We tried to summarize the discussion on M/O flags, but we (authors of the M/O flags) were busy with other things, so we could not do that. But from the discussion we found three different opinions 1. Leave M/O Flags unchanged 2. Flags independently represent DHCPv6 and DHCP lite (M-flag for

Isn't it such a long idscussion a proof for the confusion in understanding the M/O bits? Instead of leaving the discussion here, thinking that there is no confusion or be fore taking any radical changes (either discarding M or O or both flags, or making changes to the DHCPv6 protocols), it is bett

This proposal looks better and easy to understand. However, if we just rely on timeout for concluding the unavailabiliy of DHCP server, how does the client re-invoke DHCP if the DHCP server is available later in time? I think we need one bit to inform the clients about the availabilty of DHCP serv
