Configuring Multicast Snooping
To configure the general multicast snooping parameters for MX Series routers, include the multicast-snooping-options statement:
You can include this statement at the following hierarchy levels:
- [edit bridge-domains bridge-domain-name]
- [edit routing-instances routing-instance-name]
- [edit routing-instances routing-instance-name bridge-domains bridge-domain-name]
- [edit logical-systems logical-system-name routing-instances routing-instance-name]
- [edit logical-systems logical-system-name routing-instances routing-instance-name bridge-domains bridge-domain-name]
By default, multicast snooping is disabled. You can enable multicast snooping in VPLS or virtual switch instance types in the instance hierarchy or in one or more bridge domains.
If there are multiple bridge domains configured under a VPLS or virtual switch instance, the multicast snooping options configured at the instance level apply to all the bridge domains. Multicast snooping options configured at the bridge domain level only apply to that particular bridge domain. The options configured at the bridge domain take precedence over the options configured at the instance level.
 | Note: The ignore-stp-topology-change statement is supported for the virtual-switch routing instance type only and is not supported under the [edit logical-systems] hierarchy. |
| Note: The nexthop-hold-time statement is supported only at the [edit routing-instances routing-instance-name] hierarchy, and only for an instance type of virtual-switch or vpls. |
