As far as attack if someone can attach to LAN and if he knows security details he can do much better then hack IGP. But oh well if we prefer to continue to ride on current type of roads while complicating design of new vehicles to accomodate it that is fine too. Best, R. On Wed, Apr 3, 2019,

Hello Robert, > For the purpose of this discussion can someone quote the definition of LAN ? Well, sure, if you insist. I’m surprised as you’ve been around for (quite) awhile and I would have thought that you picked up on this stuff. :-) :-) :-) ISO 10589v2 defines a LAN as a “Local Area

(I have altered the subject so we can discuss the two issues in Tony's previous post separately.) There are several aspects to consider when discussing LAN support in the context of flooding optimizations: 1)Flooding topology advertisement (centralized mode only) Support for encoding LANs
