The nni-mstp boot flag changes the default behavior of the MSTP on SPBM network-to-network interface (NNI) ports. The Common and Internal Spanning Tree (CIST) is disabled automatically on the NNI, and the NNI ports can only be members of backbone VLANs (B-VLAN).

Example: Configuring nni-mstp to true

Switch:1>enable
Switch:1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch:1(config)#boot config flags nni-mstp
Warning: Please save the configuration and reboot the switch for this configuration to take effect.
Switch:1(config)#
