Donald, et al,


-        Section 3 (page 7) 3rd paragraph:

"Ethernet links between FGL TRILL switches still have only C-VLAN tagging on them"

When you talk about Ethernet Links between FGL TRILL switches, the VID is the outer Ethernet header above the TRILL header. Is it always "C-VLAN"? Why have this restriction?


-         Section 5.1: Can FGL RBridge also do VL RBridge function? For example, when the C-VLAN of the incoming frame is the VL specifiable data label, the FGL RBridge just simply performs the VL RBridge function. Is it possible?

-         Same goes with Section 5.3: when X is VL specifiable only, why can't the FGL RBridge simply decapsulates the frame as regular VL RBridge?

Thanks, Linda
