SmartFabric OS10 Spanning tree protocol with VLT

Samenvatting: Even though the VLT enabled topology provides a loop-free environment in the VLT domain, some non-VLT member ports can end up in a loop scenario. Rapid spanning tree protocol (RSTP) and rapid per-VLAN spanning tree+ (RPVST+) modes of spanning tree protocol in VLT are supported to provide a solution for this scenario. Depending on the network topology, the primary node of the VLT domain can be designated as the root bridge. ...

Instructies

Even though the VLT enabled topology provides a loop-free environment in the VLT domain, some non-VLT member ports can end up in a loop scenario. Rapid spanning tree protocol (RSTP) and rapid per-VLAN spanning tree+ (RPVST+) modes of spanning tree protocol in VLT are supported to provide a solution for this scenario. Depending on the network topology, the primary node of the VLT domain can be designated as the root bridge.

Note: Dell Technologies recommends that you enable a spanning tree (RSTP or RPVST+) before enabling VLT to avoid unintentional loops in the network.

The RPVST+ is enabled by default in Dell SmartFabric OS10. There is no need to configure RPVST+ unless the default spanning tree mode is changed.

VLT-Peer1(config)# spanning-tree mode rapid-pvst

  
The RSTP is enabled by using the following command.

  

  
VLT-Peer1(config)# spanning-tree mode rstp

  

  
For Multiple Spanning Tree Protocol (MSTP) on VLT nodes, configure both VLT peer nodes in the same MST region to avoid network loops. Ensure that the VLAN-to-instance mappings, region name, and revision ID are the same on both VLT peer nodes.

  

  
VLT-Peer1(config)# spanning-tree mode mst
VLT-Peer1(config)# spanning-tree mst configuration
VLT-Peer1(conf-mst)# instance 1 vlan 2-10
VLT-Peer1(conf-mst)# revision 10
VLT-Peer1(conf-mst)# name ExampleMSTregion
