9.3.1 Establishing the Configuration Task
Before configuring static multicast routes, familiarize yourself with the applicable environment,
pre-configuration tasks, and required data. This can help you complete the configuration task
quickly and accurately.
Applicable Environment
Static multicast route has the following functions:
l Changing RPF route
If the topology of multicast is the same as that of unicast, the transmission path of multicast
data is the same as that of unicast data. Users can change the RPF route by configuring a
static multicast route. Thus a transmission path of the multicast data, which is different
from the transmission path of unicast data, is established.
l Connecting RPF route
In the network segment where unicast routes are blocked, when multicast static routes are
not configured, packets cannot be forwarded because there is no RPF route. You can
configure multicast static routes. Therefore, the system can generate RPF routes, complete
RPF check, create routing entries, and guide the forwarding of packets.
Pre-configuration Tasks
Before configuring a static multicast route, complete the following tasks:
l Configuring a unicast routing protocol
l Configuring basic multicast functions
Data Preparation
To configure a static multicast route, you need the following data.
No.
Data
1 Multicast source address, mask or mask length
2 Unicast routing protocol
3 Filtering policy and its preference
9.3.2 Configuring a Static Multicast Route
When configuring a static multicast route, you can specify an RPF interface and an RPF neighbor
on the current multicast device.
