Description: An entry in this table represents a mapping between the TE-Class and pair. The [DSTE-PROTO] indicates that a DS TE domain can support 8 TE-Classes defined, by the pair. An administrator must defined the TE-Class he wants to support in the domain by creating appropriate entries in this table. All the LSRs in the domain, must have the same set of entries. Besides defining the TE-Classes, the entries in this table also indicate the active Class-Types within the LSR and the connection priorities it can support. More specifically:- The LSR is considered to support a particular Class-Type only if it appears in the definition of the 8 possible TE-Classes. A (setup/holding) priority associated with a LSP, on a LSR is consider to be valid only if it appears as a pair with the class-type of the connection. An empty mplsDsTeClassTable effectively disables DSTE and TE on the LSR and no (DSTE/TE) LSPs can be established on the LSR. There are no other restrictions on how any of the 8 Class-Types can be paired up with any of the 8 preemption priorities to form a TE- class[DSTE-PROTO].
