In the PIM-SM network, the ASM model supports the following methods to obtain an RP. You
can select the method as required.
l
A multicast group may be in the service range of the dynamic RP and the static RP
simultaneously. By default, The switch prefers the dynamic RP. If the static RP precedence is
configured, the static RP is preferred.
Different multicast groups correspond to different RPs. Compared with all groups corresponding
to an RP, this can reduce the burden of an RP and enhance the robustness of the network.

7.3.2 Enabling IP Multicast Routing

Prior to configuring all IPv4 multicast features, enable IPv4 multicast routing.

If G is not in the SSM group address range, the ASM model is used to provide multicast
services.
Static RP: To obtain a static RP, manually configure RP on each switch in the PIM-SM
domain. For the large-scale PIM network, configuring the static RP is complicated. To
enhance the robustness and the operating management of the multicast network, the static
RP is usually used as the backup of the BSR-RP.
