[rbridge] Consensus Check: Point to Point links

[Eric Gray]

Silvano,

	It is not exactly true that bridges are never addressed at the 
MAC layer.  Consider, for example, how bridges are typically managed
using SNMP, or HTML.

	However, the case is still general, because everything you say
about RBridges - and the likelihood that they might be connected via
P2P links - similarly applies to other devices (L2 end-stations, such
as routers, for example.  And objecting that it may (or may not) be
easy for these devices to determine that a link is P2P is an argument
that applies equally to RBridges.

	I think it is not possible at this point to argue that there is
consensus to do this work here, in the TRILL working group.
