Enable the MSTIs. enable stpd {} For a more detailed configuration example, see MSTP Configuration Example on page 578. MSTP Operation To further illustrate how MSTP operates and converges, Figure 53 displays a network with two MSTP regions. Each region contains three MSTP bridges and one MSTI. The overall network topology also contains one CIST root bridge (Switch A, which has the lowest bridge ID), one interconnecting 802.1w bridge (Switch D), and 10 full duplex, point-to-point segments. VLAN Default spans all of the bridges and segments in the network, VLAN engineering is local to its respective region, and STPD S0 is configured as the CIST on all bridges. = boundary port = master port = MSTI root port 1 Switch D 2 MSTP Region 1 MSTP Region 2 3 Switch A CIST root CIST regional root MSTI regional root 4 5 8 9 CIST Switch E regional root 6 7 10 Switch B Switch C Switch F MSTI regional root Switch G STPD SI configured on switch A-C VLAN engineering assigned to SI STPD SI configured on switch E-G VLAN finance assigned to SI EX_165 Figure 53. MSTP Topology with the CIST Root Bridge Contained within a Region MSTP Region 1 consists of the following: • Three bridges named Switch A, Switch B, and Switch C • One MSTI STPD named S1 with an MSTI ID of 1 • VLAN Engineering mapped to the MSTI STPD, S1 Chapter 18.
