Configuring Multicast Snooping to Ignore Spanning Tree Topology Change Messages
You can configure the multicast snooping process for a virtual switch to ignore VPLS root protection topology change messages.
Before you begin, complete the following tasks:
Configure the spanning-tree protocol. For configuration details, see one of the following topics:
Configure VPLS root protection. For configuration details, see one of the following topics:
To configure multicast snooping to ignore spanning tree topology change messages:
Configure a virtual-switch routing instance to isolate a LAN segment with its VSTP instance.
- You can configure multicast snooping to ignore messages about spanning tree topology changes for the virtual-switch routing-instance type only.
Enable configuration of a virtual switch routing instance:
[edit]user@host# edit routing-instances routing-instance-nameuser@host# set instance-type virtual-switch Enable configuration of a bridge domain:
[edit routing-instances routing-instance-name]user@host# edit bridge-domains bridge-domain-nameuser@host# set domain-type bridgeConfigure the logical interfaces for the bridge domain in the virtual switch:
[edit routing-instances routing-instance-name bridge-domains bridge-domain-name]user@host# set interface interface-name- Configure the VLAN identifiers for the bridge domain in the virtual switch. For detailed information, see Configuring a Virtual Switch Routing Instance.
Configure the multicast snooping process to ignore any spanning tree topology change messages sent to the virtual switch routing instance:
[edit routing-instances routing-instance-name bridge-domains bridge-domain-name]user@host# set multicast-snooping-options ignore-stp-topology-changeVerify the configuration of multicast snooping for the virtual-switch routing instance to ignore spanning tree topology change messages:
