Hi Egor, We were using the wrong alias it is mpls@ietf.org and not mpls@ietf.com. Thanks, Vishwas ---------- Forwarded message ---------- From: Vishwas Manral <vishwas.ietf@gmail.com> Date: Fri, Apr 16, 2010 at 6:59 AM Subject: Re: [mpls] LDP IPv6 To: Egor Zimin <lesnix@gmail.com> Cc: Mikael Abrahamsson <swmike@swm.pp.se>, Rob Shakir <rjs@eng.gxn.net>, mpls@ietf.com, faz@netfm.co.uk Hi Egor, 1. As Mikael brought out the question of what else is missing I brought up the MIB and RSVP-TE issues. I will bring the details out in another mail with the correct subject line. 2. I guess now that we have more knowledge of the draft we can actually try to push it further.
