RSTP configuration
RSTP mode is supported on VLT ports. Before you configure VLT on peer switches, configure RSTP in the network. RSTP
prevents loops during the VLT startup phase.
● Enable RSTP on each peer node in CONFIGURATION mode.
spanning-tree mode rstp
Configure RSTP — peer 1
OS10(config)# spanning-tree mode rstp
Configure RSTP — peer 2
