Description

Configures Multiple Spanning Tree Protocol (MSTP). MSTP is defined in the IEEE 802.1Q-2003 specification and is used to create a loop-free topology in networks with multiple spanning tree regions.

Note

MX Series routers and QFX5100 switches do not support the interface all statement to enable MSTP on all interfaces with one command.

On MX Series routers, you must enable MSTP on interfaces individually using the set ... protocols mstp interface interface-name statement.

On QFX5100 switches, to apply MSTP configuration to more than one interface, you must first configure one or more interface ranges for the interfaces on which you want to configure MSTP, and then issue the set protocols mstp interface interface-name command using each interface range as the interface-name parameter.

The remaining statements are explained separately. See CLI Explorer.
