Multi Protocol Label Switching (MPLS) has defined a mechanism to load balance traffic flows using Entropy Labels (EL). An LSR inserts the EL Indicator and the EL label only if the LSR that pops them has the capability of processing them. This draft defines a mechanism to signal that capability using link state Interior Gateway Protocols (IGP). This mechanism is useful when the label advertisement is also done via that IGP.
