[rbridge] Time for a summary?

[Silvano Gai]

Eric,

Can you please reply to the following question?

                +---------------+
     100        |               |     X
--------------->|    RBridge    |----------------->
Not encapsulated|               |  Encapsulated
                +---------------+


When a frame of 1,000 bytes is received not-encapsulated by an RBridge
and transmitted encapsulated, how big is it (X) after the TRILL header
is added on Ethernet?
