Flush MAC Addresses after a Topology Change
Dell EMC Networking OS has an optimized MAC address ush mechanism for RSTP, MSTP, and PVST+ that ushes addresses only when
necessary, which allows for faster convergence during topology changes.
However, you may activate the ushing mechanism dened by 802.1Q-2003 using the tc-flush-standard command, which ushes
MAC addresses after every topology change notication.
To view the enable status of this feature, use the show running-config spanning-tree mstp command from EXEC Privilege
mode.
MSTP Sample Congurations
The running-congurations support the topology shown in the following illustration.
The congurations are from Dell EMC Networking OS systems.
Figure 93. MSTP with Three VLANs Mapped to Two Spanning Tree Instances
Router 1 Running-Conguration
This example uses the following steps:
1 Enable MSTP globally and set the region name and revision map MSTP instances to the VLANs.
2 Assign Layer-2 interfaces to the MSTP topology.
3 Create VLANs mapped to MSTP instances tag interfaces to the VLANs.
