Configuring Multicast Routing and Forwarding

Configuration Prerequisites

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

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.

Follow these steps to configure a multicast static route:

To do...

Use the command...

Remarks

Enter system view

system-view

Configure a multicast

static route

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 ]

Required

No multicast static route

configured by default.

Delete multicast static

routes

delete ip rpf-route-static [ vpn-instance

vpn-instance-name ]

Optional

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 connecting 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).
