Subject: [rbridge] codepoint consideration for Multi Topology mapping

Hi, 

Multi topology routing should be naturally supported by TRILL since it reuse the control layer of IS-IS. However, the current trill header does not have the code point for MT routing. We know that ISIS can use the DSCP field to map the MT IDs. I think that we can extend a new option field of TRILL header or to occupy some bits of the VLAN field to map the MT IDs. 

What is your opinion?
