[rbridge] Consensus Check: Egress processing of unicast not locallyknown

[Dinesh G Dutt]

Anoop,

Did you mean that in the example that he quoted the reason for dropping 
the frame was access control (such as 802.1x authenticated) ? To me 
access control is a very generic term that can also include things such 
as security ACLs.

"Access Control" is orthogonal to forwarding. For example, I can have IP 
FIB entries or MAC table entries associated with a frame, but can drop a 
specific frame such as those going to "port 80" as part of access 
control. What Donald is specifying *seems* to be in addition to access 
control.
