This question was asked during the meeting, and yes we did think through the details.
Consider the case where you only use the P-bit scheme. However, on each segment, there could be standard L2 bridges which don't use NDproxy. Those L2 bridges are responsible for ensuring that that segment is loop-free. To P-bit NDproxies, NDproxies which run STP are the same in this respect as normal L2 bridges. As a result, the two schemes co-exist fine. -Dave > -----Original Message----- > From: Erik Nordmark [mailto:[EMAIL PROTECTED] > Sent: Tuesday, March 15, 2005 11:22 AM > To: Dave Thaler > Cc: IPv6 > Subject: ndproxy loop prevention > > > I didn't make the IPv6 meeting last week so I looked over the slides. > > I'm a bit concerned about the complexity of having both the 'P' bit and > the optional STP.
