Thank you, Gert
I'd very much like to ask the same question my head-office which  
distributes this kind of reference material. The only purpose ES20 serve  
in their design is to establish VPLS connection between two (four in the  
future) core c7604.
I think this setup hardly justifies the efforts and money that's been  
invested into it. Correct me if I'm wrong but for 2 MLS switches sitting  
in the same rack it is too much of an overhead to configure VPLS. A trunk  
link would be considerably simpler and more reliable in this case.
