Enabling IP multicast routing in a VPN instance
Step
1. Enter system view.
2. Create a VPN instance and
enter VPN instance view.
3. Configure a route
distinguisher (RD) for the VPN
instance.
4. Enable IP multicast routing.
For more information about the ip vpn-instance and route-distinguisher commands, see MPLS Command
Reference.

Configuring multicast routing and forwarding

Before configuring multicast routing and forwarding, complete the following tasks:
• Configure a unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
Enable PIM (PIM-DM or PIM-SM).
•
Determine the minimum TTL value required for a multicast packet to be forwarded.
•
• Determine the maximum number of downstream nodes for a single multicast forwarding table entry.
Determine the maximum number of entries in the multicast forwarding table.
•
Configuring static multicast routes
By configuring a static multicast route for a given multicast source, you can specify an RPF interface or an
RPF neighbor for multicast traffic from that source. You can use the undo ip rpf-route-static command to
remove a specific static multicast route and use the delete ip rpf-route-static command to remove all static
multicast routes.
When you configure a static multicast route, you cannot specify an RPF neighbor by providing the type
and number (interface-type interface-number) of the interface that connects the RPF neighbor if the
interface of the RPF neighbor is a Layer 3 Ethernet interface, Layer 3 aggregate interface, Loopback
interface, Layer 3 RPR logical interface, or VLAN interface. Instead, you can specify such an RPF
neighbor only by its address (rpf-nbr-address).
To configure a static multicast route:
Step
1. Enter system view.
