PIM-SM Configuration
621
Perform the following configuration in PIM view.
When configuring a C-RP, if the range of the served multicast groups is not
specified, the C-RP will serve all multicast groups. Otherwise, it will serve only
those within the specified range. It is suggested to configure C-RPs on routers over
the backbone network.

the backbone network.
CAUTION: In this command, parameter acl-number is not used to perform match
filtering, but to define the range of a group. The range of groups under permit will
be broadcasted as the served group ranges of RP. The other choices such as deny
are disabled.

Configuring Static RP
RP is the core router in multicast routing. Since the dynamic RP elected through
the BSR mechanism may fail, you can configure a static RP as a standby RP to
enhance the robustness as well as the operability of the multicast network.

Perform the following configuration in PIM view.
If a static RP is in use, all routers in the PIM domain must adopt the same
configuration. If the configured static RP address is the interface address of the
local router under UP state, the router will function as the static RP. It is
unnecessary to enable PIM on the interface that functions as static RP.

When the RP elected by BSR mechanism is valid, static RP does not work.
Configuring the Hello
message Interval
After PIM is enabled on an interface, it will send Hello messages at specified
intervals.
