Configuring administrative scoping
When administrative scoping is disabled, a BIDIR-PIM domain has only one BSR. The BSR manages the
whole network. To manage your network more effectively and specifically, you can divide the BIDIR-PIM
domain into multiple admin-scoped zones. Each admin-scoped zone maintains a BSR, which serves a
specific multicast group range. The global scope zone also maintains a BSR, which serves 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 all routers in the BIDIR-PIM domain.

Configuring an admin-scoped zone boundary
The boundary of each admin-scoped zone is formed by ZBRs. Each admin-scoped 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-scoped zone boundary.
Perform the following configuration on routers that you want to configure as a ZBR.
