Follow these steps to enable IP multicast routing in a VPN instance: 

Enter system view 

— 

Create a VPN instance and 
enter VPN instance view 

ip vpn-instance 
vpn-instance-name 

— 

Configure a route distinguisher 
(RD) for the VPN instance 

route-distinguisher 
route-distinguisher 

Required 

No RD is configured by default.

Enable IP multicast routing 

Required 

Disabled by default 

 

For details about the ip vpn-instance and route-distinguisher  commands, refer to MPLS L3VPN 

Commands in the MPLS Volume. 

 

Before configuring multicast routing and forwarding, complete the following tasks:  

z 

Configure a unicast routing protocol so that all devices in the domain are interoperable at the 

network layer. 

z 

Enable PIM (PIM-DM or PIM-SM). 

Before configuring multicast routing and forwarding, prepare the following data: 

z 

The maximum number of downstream nodes for a single multicast forwarding table entry 

z 

The maximum number of entries in the multicast forwarding table 

By configuring a multicast static route for a given multicast source, you can specify an RPF interface or 

an RPF neighbor for multicast traffic from that source.  

Follow these steps to configure a multicast static route: 

To do... 

Use the command...
