Configuring VPLS Root Protection Topology Change Actions to Control Global Spanning Tree Behavior
To configure VPLS root protection topology change actions to control global spanning tree behavior:
- Enable configuration of the spanning-tree protocol:
[edit]
user@host# edit protocols (STP Type) (mstp | rstp | vstp) - (Optional) Change the priority of the backup bridge in
a VPLS multihomed Layer 2 ring with MPLS infrastructure:
[edit protocols (rstp | mstp | vstp)]
user@host# set backup-bridge-priority vpls-ring-backup-bridge-priority - (Optional) Change number of seconds to hold before switching
to the primary priority when the first core domain comes up:
[edit protocols (rstp | mstp | vstp)]
user@host# set priority-hold-time seconds - Configure the system identifier for bridges in the ring:
[edit protocols (rstp | mstp | vstp)]
user@host# set system-id system-id-value bridge-host-ip-address(es)The system-id-value is configured in the format nnnnnn:nnnnnn, where n = any digit from 0 to 9.
Each bridge-host-ip-address is a valid host IP address with a /32 mask.
Note: There are no default values for the system identifier or host IP addresses.
- Configure bridges to flush the MAC address cache (of the
MAC addresses learned when other interfaces ports were blocked) when
the spanning-tree topology changes:
[edit protocols (rstp | mstp | vstp)]
user@host# setvpls-flush-on-topology-change Verify the configuration of VPLS root protection topology change actions to control global spanning tree behavior:
[edit]protocols {(mstp | rstp | vstp) {backup-bridge-priority priority; # Default is 32,768.priority-hold-time seconds; # Default is 2 seconds.system-id system-id-value {ip-address;}vpls-flush-on-topology-change;}}
