RPVST+ configuration
Configure RPVST+ on both the VLT peers. This creates an RPVST+ instance for every VLAN configured in the system. With
RPVST+ configured on both VLT nodes, OS10 supports a maximum of 60 VLANs. The RPVST+ instances in the primary VLT
peer control the VLT port channels on both the primary and secondary peers.
NOTE: RPVST+ is the default STP mode running on the switch. Use the following command only if you have another
variant of the STP running on the switch.
Enable RPVST+ on each peer node in CONFIGURATION mode.
spanning-tree mode rapid-pvst
Configure RPVST+ peer 1
OS10(config)# spanning-tree mode rapid-pvst
Configure RPVST+ peer 2
