NOTE:
IEEE 802.1w standard-based RSTP implementation runs on one STG (i.e. same as one spanning tree
instance) only. As a result, if 'rstp' mode is selected under the /cfg/mrst/mode command, then only a
single RSTP instance (default for STG 1) is supported for all VLANs, including the Default VLAN 1.
If multiple spanning tree instances are required, then select 'mstp' mode so that multiple VLANs are handled
by multiple spanning tree instances, as specified by IEEE 802.1s standard-based MSTP implementation.
IEEE 802.1s MSTP supports rapid convergence using IEEE 802.1w RSTP.
PVST+ does not support rapid convergence in current versions.
NOTE:
The following configurations are
HP PVST+ (default Spanning Tree setting) is NOT interoperable with Cisco Rapid PVST+.
HP MSTP/RSTP (with mode set to either 'mstp' or 'rstp') is NOT interoperable with Cisco Rapid PVST+.
The following configurations are supported:
HP PVST+ (default Spanning Tree setting) is interoperable with Cisco PVST+.
HP MSTP/RSTP (with mode set to 'mstp') is interoperable with Cisco MST/RSTP.
