Configuring administrative scoping
With administrative scoping disabled, a BIDIR-PIM domain has only one BSR. The BSR manages the
whole network. To manage your network more effectively and specifically, partition the BIDIR-PIM
domain into multiple admin-scoped zones. Each admin-scoped zone maintains a BSR to provide services
for a specific multicast group range. The global-scoped zone also maintains a BSR to provide services for
all the rest multicast groups.
Enabling administrative scoping
Before you configure an admin-scoped zone, you must enable administrative scoping first.
Perform the following configuration on routers that you want to configure as a C-BSR and ZBR.
To enable administrative scoping:

3. Enable administrative
scoping.
c-bsr admin-scope Disabled by default.
Configuring an admin-scoped zone boundary
The boundary of each admin-scoped zone is formed by ZBRs. Each admin-scoped zone maintains a BSR
to provide services for a specific multicast group range. Multicast protocol packets (such as assert
messages and bootstrap messages) that belong to this range cannot cross the admin-scoped zone
boundary.
Perform the following configuration on routers that you want to configure as a ZBR.
