Associate a subnet with a multicast domain
tip
- Before associating a subnet, ensure that the Virtual Private Cloud (VPC) to which the subnet belongs has established an Network Instance Attachment with the Transit Router (TR) instance.
- A single multicast domain supports associating a maximum of 10 subnets by default. If the default quota is insufficient, see create a quota application to submit a quota increase request.
- Click the name of the target TR instance.
- In the zone below Basic information, select the Multicast domain tab.
- Click the name of the target multicast domain.
- Click Associate subnet, and sequentially select the VPC and subnet.
- Click Associate to complete the action.
Disassociate a subnet from a multicast domain
tip
- Before disassociating a subnet, ensure that no multicast sources or multicast members belong to the subnet. If any, delete the multicast sources and multicast members first. For procedure, see Delete a multicast source and Delete a multicast member.
- When deleting a subnet in the VPC console, subnets already associated with a multicast domain are automatically disassociated.
- Click the name of the target TR instance.
- In the zone below Basic information, select the Multicast domain tab.
- Click the name of the target multicast domain.
- Click Disassociate to the right of the target subnet.
- Click Disassociate to complete the action.
