Rapid Spanning Tree Protocol (RSTP) on Multi-switch Link Aggregation Groups (MLAGs)

You can configure Rapid Spanning Tree Protocol (RSTP) on Multi-switch Link Aggregation Group (MLAG) peers and access switches, which can prevent loops in networks containing MLAG topology. This allows third-party switches to be connected to MLAG topology (as access switches) and an RSTP domain can span ExtremeXOS and third-party switches.

In typical MLAG deployments, connections can exist between access switches, which can cause data loops. By configuring RSTP on all the nodes, loops can be effectively prevented.

RSTP is supported in simple MLAG, W-MLAG, and two-tier MLAG topologies.
