5.8.3 Configuring Spanning Tree Protocols on m-VPLS
RSTP and MSTP are supported on the m-VPLS only, not on a v-VPLS. When
implementing an RSTP or MSTP, take note of the following conditions:
• RSTP and MSTP cannot run concurrently on the system.
• An SAP must be created in the m-VPLS for each port or LAG that will participate
in the STP protocol. STP must then be enabled on each SAP in m-VPLS, using
the no shutdown command. The SAP is created using the VLAN ID notation
“no-tag”.
• The STP parameters must be configured for the m-VPLS, including no shutdown
to enable STP and 'mode' to specify whether RTSP or MSTP protocol is required.
• For MSTP, up to 15 instances can be configured with different VLAN ranges for
the MST instance. VLANs which are not included explicitly in an MSTP instance
fall into the default MSTP instance 0. For the MST instance, the path-cost and
port-priority are configured at the SAP level.
Note that traditional L2 switches running MSTP protocol assign all VLANs to the IST
instance per default. The operator can re-assign individual VLANs to a given MSTI
by configuring per VLAN assignment.
