Configure the BS period
c-bsr interval interval
Optional
For the default value, see the note below.
Configure the BS timeout
c-bsr holdtime interval
Optional
For the default value, see the note below.
About the BS period:
z
By default, the BS period is determined by this formula: BS period = (BS timeout – 10) / 2. The
default BS timeout is 130 seconds, so the default BS period = (130 – 10) / 2 = 60 (seconds).
z
If this parameter is manually configured, the system will use the configured value.
About the BS timeout:
z
By default, the BS timeout value is determined by this formula: BS timeout = BS period × 2 + 10.
The default BS period is 60 seconds, so the default BS timeout = 60 × 2 + 10 = 130 (seconds).
z
If this parameter is manually configured, the system will use the configured value.
In configuration, make sure that the BS period value is smaller than the BS timeout value.
Configuring Administrative Scoping
With administrative scoping disabled, a PIM-SM domain has only one BSR. The BSR manages the
whole network. To manage your network more effectively and specifically, you can partition the PIM-SM
domain into multiple admin-scope zones. Each admin-scope zone maintains a BSR, which serves a
specific multicast group range; while the global scope zone also maintains a BSR, which serves all the
rest multicast groups.
Enabling administrative scoping
Before configuring an admin-scope zone, you must enable administrative scoping first.
Perform the following configuration on all routers in the PIM-SM domain.
