4. Enable IP multicast routing.

Configuring multicast routing and forwarding

Prerequisites

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 multicast static routes

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.
To do...
1. Enter system view.
2. Configure a
multicast static
route.
3. Delete multicast
static routes.
When configuring a multicast static 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
type of the RPF neighbor is Ethernet, Layer 3 aggregate, Loopback, RPR, or VLAN-interface. Instead, you
can specify such an RPF neighbor only by its address (rpf-nbr-address).

Configuring a multicast routing policy

You can configure the router to determine the RPF route based on the longest match principle. For more
information about RPF route selection, see
Use the command...
route-distinguisher route-distinguisher
multicast routing-enable
Use the command...
system-view
ip rpf-route-static [ vpn-instance vpn-instance-name ]
source-address { mask | mask-length } [ protocol
[ process-id ] ] [ route-policy policy-name ]
{ rpf-nbr-address | interface-type interface-number }
[ preference preference ] [ order order-number ]
delete ip rpf-route-static [ vpn-instance
vpn-instance-name ]
