Table 6-9 Enabling PIM-SM protocol
Start PIM-SM on the interface
Disable PIM-SM on the interface
Repeat this operation to enable PIM-SM on other interfaces. Only one multicast routing
protocol can be enabled on an interface at a time. Once PIM-SM is enabled on an
interface, PIM-DM cannot be enabled on it, and vice versa.

6.3.4 Configuring the sending interval for the Hello packets of the interface

After started on the interface, PIM-SM protocol periodically broadcasts Hello packets to
discover PIM neighbors and to judge which router serves as the designated router
(DR).
See 6.2.3 Configuring Sending Interval for the Hello Packets.

6.3.5 Configuring C-BSR

In a PIM domain, one or more C-BSRs should be configured. A BSR (Bootstrap Router)
is elected automatically among C-BSRs, to take charge of RP information collecting
and broadcasting. The automatic election among C-BSRs is described as follows:
One PIM-SM-enabled interface shall be specified when configuring a router as a
C-BSR.
At first, every C-BSR regards itself as the BSR of the PIM-SM domain and sends
Bootstrap message, taking the IP address of the specified interface as the BSR
address.
When receiving a Bootstrap message from another router, the C-BSR compares the
BSR address and the priority of that router with those of itself. When they are of equal
priority, the one with greater BSR address is considered the BSR. Specifically, if the
BSR address of the received message is greater, the C-BSR will replace its BSR
address with it and stop regarding itself as the BSR. Otherwise, it will keep its BSR
address as well as the BSR role.
Please perform the following configurations in PIM view.
