NOTE:
A
bout the BS period:
• By default, the BS period is determined by this formula: BS period = (BS timeout – 10) / 2. The defaul
t
BS timeout is 130 seconds, so the default BS period = (130 – 10) / 2 = 60 (seconds).
• If this parameter is manually configured, the system will use the configured value.
A
bout the BS timeout:
• 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).
• If this parameter is manually configured, the system will use the configured value.
CAUTION:
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.
1. 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.
Follow these steps to enable administrative scoping:

Required
Disabled by default
2. Configuring an admin-scope zone boundary
The boundary of each admin-scope zone is formed by ZBRs. Each admin-scope zone maintains a BSR,
which serves a specific multicast group range. Multicast protocol packets (such as assert messages and
bootstrap messages) that belong to this range cannot cross the admin-scope zone boundary.
Perform the following configuration on routers that can become a ZBR.
