Usage Guidelines

Usage Scenario

The multicast function should be enabled in a VPN instance before you configure all the multicast commands.

Precautions

After the undo multicast routing-enable command is run, all the multicast configurations of the public network instance is cleared. If the multicast services are running in the instance, the multicast services are interrupted when this command is executed. To restore the multicast service on the instance, you must re-configure the corresponding commands.

Example

# Enable the multicast function in a VPN instance mytest.

<HUAWEI> system-view
[~HUAWEI] ip vpn-instance mytest
[*HUAWEI-vpn-instance-mytest] ipv4-family
[*HUAWEI-vpn-instance-mytest-af-ipv4] route-distinguisher 100:1
