VPLS Multihoming: System Identifier for Bridges in the Ring
When an MX Series router or an EX Series switch in a VPLS multihomed Layer 2 ring is running a spanning-tree protocol with root protection enabled, you can modify the default actions taken by the router or switch when the topology changes. To do this, configure the VPLS root protection topology change actions.
The system identifier for bridges in the ring is not configured by default.
To configure a system identifier for bridges in the ring, you can use the following statement:
- system-id system-id-value bridge-host-ip-address(es)
You can include the statement at the [edit protocols (mstp | rstp | vstp)] hierarchy level (to control global spanning-tree protocol behavior) or at the [edit protocols vstp vlan vlan-id] hierarchy level (to control a particular VLAN).
 | Note: VPLS root topology change actions are configured independently of VPLS, the spanning-tree protocol, or the spanning-tree protocol root protect option. |
