IB>> This is an interesting requirement. Fortunately, it is possible to realize this requirement via GMPLS signaling by including several ASSOCIATION objects of the same type into the same Path message. For instance, one of them will indicate that the signalled LSP belongs to the nested VCAT group, while another -to the nesting VCAT group.
