Multiple I-SID Registration Protocol Lite
The 802.1Qbe—Multiple I-SID Registration Protocol (MIRP) standard provides the ability to flush learned
MAC address registration entries held in the filtering database of an I-component on a per I-SID basis. The
backbone service instance identifier (I-SID) is a field in the backbone service instance tag which identifies
the backbone service instance of a frame. MIRP defines mechanisms for I-SID flushing, and has the required
capabilities to handle topology changes that occur in networks attached to a provider backbone bridged
