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,

Hello Robert,

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
For the purpose of this discussion can someone quote the definition of LAN
?
Why ?
*1* In most modern data centers I do not see any LANs. Even compute nodes
are L3 nodes connected over /31 or /30 to TORs. From fabric IGP this is
passive interface.
*2* In slightly older DCs there are redundant
I agree as well.
Thanks,

In reply to my own post, here is my opinion regarding including LANs in the
Flooding Topology:
While I think it would be "nice" and simplifying to be able to ignore LANs, I
think we are unable to do so because the possibility that LANs are actually in
use as transit links in some topologies
