The MSTP-Fabric Connect Multi Homing feature allows MSTP or RSTP network to be multi-homed into a Fabric Connect network, providing a loop-free topology. MSTP-Fabric Connect Multi Homing enables an MSTP network to be multihomed into the SPB Fabric network through single node-to-multiple nodes or multiple nodes-to-multiple nodes.

Important
You must enable MSTP-Fabric Connect Multi Homing before you establish multihoming with an MSTP network.
MSTP-Fabric Connect Multi Homing uses I-SID 16777003. The switch creates this I-SID automatically and it cannot be modified.
MSTP-Fabric Connect Multi Homing is supported on SPBM mode only.
