Note:
About the bootstrap timeout time:
z
By default, the bootstrap timeout time is determined by this formula: Bootstrap
timeout = 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 the
default 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 bootstrap
timeout time.
6.3.5 Configuring an RP
An 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 RP
configuration is just a backup means for the dynamic RP election mechanism to
enhance the robustness and operation manageability of a multicast network.
I. Configuring a static RP
If there is only one dynamic RP in a network, manually configuring a static RP can avoid
communication interruption due to single-point failures and avoid frequent message
exchange between C-RPs and the BSR. To enable a static RP to work normally, you
must perform this configuration on all the devices in the PIM-SM domain and specify
the same RP address.
