HP MSR2000/3000/4000 Router Series IP Multicast Configuration Guide

36
NOTE:
The device can route and forward multicast data only through the primary IP addresses of interfaces,
rather than their secondary addresses or unnumbered IP addresses. For more information about primar
y
and secondary IP addresses, and IP unnumbered, see Layer 3—IP Services Configuration Guide .
Enabling IP multicast routing
Enable IP multicast routing before you configure any Layer 3 multicast functionality on the public network
or VPN instance.
To enable IP multicast routing:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enable IP multicast routing
and enter MRIB view.
multicast routing [ vpn-instance
vpn-instance-name ]
By default, IP multicast routing is
disabled.
Configuring multicast routing and forwarding
Before you configure 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-DM or PIM-SM.
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 the multicast traffic from that source.
To configure a static multicast route:
Step Command Remarks
1. Enter system
view.
system-view
N/A
2. Configure a
static multicast
route.
ip rpf-route-static [ vpn-instance vpn-instance-name ]
source-address { mask-length | mask } { rpf-nbr-address
| interface-type interface-number } [ preference
preference ]
By default, no static
multicast route exists.
3. (Optional.)
Delete static
multicast routes.
• Delete a static multicast route:
undo ip rpf-route-static [ vpn-instance
vpn-instance-name ] source-address { mask-length |
mask } { rpf-nbr-address | interface-type
interface-number }
• Delete all static multicast routes:
delete ip rpf-route-static [ vpn-instance
vpn-instance-name ]
N/A
