Use undo multicast routing-enable to disable IP multicast routing.
By default, IP multicast routing is disabled.
You must enable IP multicast routing on the public network or VPN instance before you can use other
Layer 3 multicast commands in the corresponding instance.
The device does not forward any multicast packets before IP multicast routing is enabled.
Examples
# Enable IP multicast routing on the public network.
<Sysname> system-view
[Sysname] multicast routing-enable
# Enable IP multicast routing in VPN instance mvpn.
<Sysname> system-view
[Sysname] ip vpn-instance mvpn
[Sysname-vpn-instance-mvpn] route-distinguisher 100:1
