Hi, I tried to raise this issue in the monday's meeting, but let me try to augement it a bit.
I have a concern that we're trying to solve all the possible problems with bridge-like ND-proxies. (After all, we're engineers and we like to solve the problems..) But, I think we need to really consider whether we NEED or WANT to solve those problems. - what's the applicability of bridge-like ND-proxy? * replace the "(consecutive) simple NAT boxes for home" deployment model? * a model applicable in scenarios where deploying a router would not work * an ability to expand a /64 over a few links of different L2 media in home (or similar networks) * single admin domain/trusted environment (where SEND doesn't matter)? - what's the non-applicability of bridge-like ND-proxy? * building large ad-hoc networks * a mechanism to replace all of your Ethernet switches / bridges * a replacement for routers (probably missed some but..) Based on this, I have a very strong gut feeling that we're going into a very, very questionable direction if we want to implement e.g.: - spanning tree protocol (implying at least 3 boxes which are not connected in serial) - supporting multiple routers connected in different branches of the bridge mesh - *having to* support SEND in every case (sure, supporting SEND would be nice but if it's too much bother..) I don't think it's the goal to emulate bridges as closely as possible, as bridges (or Ethernet switches) are generic devices. I don't think we want this to be. Of course, we could write a problem statemetn for ND proxies but Im not sure it's required. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks.
