Which three configuration parameters must match on all switches within the same MSTP region? (Choose three.)
Which three configuration parameters must match on all switches within the same MSTP region? (Choose three.)
In Multiple Spanning Tree Protocol (MSTP), for switches to be in the same MSTP region, three specific configuration parameters must match: the VLAN to instance mapping, the revision level, and the configuration name. The VLAN to instance mapping determines which VLANs are part of which MST instances. The revision level is a user-defined value that identifies the region version, and the configuration name is the alphanumeric identifier for the region. These parameters ensure that all switches in the same MSTP region share a consistent topology view for optimal spanning tree calculations.
I think it's ABE When enabling MSTP, you define one or more MSTP regions. An MSTP region defines a logical domain where multiple spanning-tree instances (MSTIs) can be administered independently of MSTIs in other regions, setting the boundary for bridge protocol data units (BPDUs) sent by one MSTI. An MSTP region is a group of switches that is defined by three parameters: Region name—User-defined alphanumeric name for the region. Revision level—User-defined value that identifies the region. Mapping table—Numerical digest of VLAN-to-instance mappings. https://www.juniper.net/documentation/us/en/software/junos/stp-l2/topics/topic-map/spanning-tree-configuring-mstp.html
Relate the juniper doc which you shared, in the MSTP CLI [edit ... protocols mstp] user@switch# set configuration-name configuration-name Therefore if we said the CLI should be "configuration-name". However, Maybe the name of this parameters call "region name"?
Correct
ABC valid answers
Region name and configuration name are basically the same. But the question is looking for specifically for config parameter. In config, the word used is configuration-name.
Wrong. Correct answer ABE An MSTP region is a group of switches that is defined by three parameters: Region name—User-defined alphanumeric name for the region. Revision level—User-defined value that identifies the region. Mapping table—Numerical digest of VLAN-to-instance mappings.
edit protocols mstp set Configuration-name region1 set revision-level 1 set msti 1 vlan [1-4094] set protocols mstp interface all
tricky one, since configuration-name and region name refer to the same thing, since they mention config parameter, it choose ABC
