Operation Manual – MulticastH3C S5500-EI Series Ethernet Switches Chapter 7 PIM Configuration7-25Note:About the bootstrap timeout time:z By default, the bootstrap timeout time is determined by this formula: Bootstraptimeout = Bootstrap interval × 2 + 10. The default bootstrap interval is 60 seconds,so the default bootstrap timeout = 60 × 2 + 10 = 130 (seconds).z If this parameter is manually configured, the system will use the configured value.About the bootstrap interval:z By default, the bootstrap interval is determined by this formula: Bootstrap interval =(Bootstrap timeout – 10) / 2. The default bootstrap timeout is 130 seconds, so thedefault bootstrap interval = (130 – 10) / 2 = 60 (seconds).z If this parameter is manually configured, the system will use the configured value.Caution:In configuration, make sure that the bootstrap interval is smaller than the bootstraptimeout time.7.3.5 Configuring an RPAn RP can be manually configured or dynamically elected through the BSR mechanism.For a large PIM network, static RP configuration is a tedious job. Generally, static RPconfiguration is just a backup means for the dynamic RP election mechanism toenhance the robustness and operation manageability of a multicast network.I. Configuring a static RPIf there is only one dynamic RP in a network, manually configuring a static RP can avoidcommunication interruption due to single-point failures and avoid frequent messageexchange between C-RPs and the BSR. To enable a static RP to work normally, youmust perform this configuration on all the devices in the PIM-SM domain and specifythe same RP address.Follow these steps to configure a static RPTo do… Use the command… RemarksEnter system view system-view —Enter PIM view pim —
