ERS8600-1:5(config)# spanning-tree mstp region region-name region2 region-version 1
ERS8600-2: Step 1 – Add MSTP configuration
ERS8600-2:5# config mstp region name region2
ERS8600-2:5# config mstp region revision 1
ERS4550T-1: Step 1 – Add MSTP configuration
4550T-1(config)# spanning-tree mstp region region-name region2 region-version 1
ERS4528GT-2: Step 1 – Add MSTP configuration

4.2 Verify Operations

4.2.1 Verify CIST Root and Regional Root
Step 1 – Verify that the CIST root bridge is C3750-1. Verify that the regional root bridge is C3750-1 for
the region named ―region1‖ and 8600-2 for the region named ―region2‖. There should only be one
forwarding port between the regions which should be via port 1/23 on 8600-1.
