Configuring administrative scoping
When administrative scoping is disabled, a PIM-SM domain has only one BSR. The BSR manages the
whole network. To manage your network more effectively and specifically, partition the PIM-SM domain
into multiple admin-scope zones. Each admin-scope zone maintains a BSR, which serves a specific
multicast group range. The global scope zone also maintains a BSR, which serves all the remaining
multicast groups.
Enabling administrative scoping
Before you configure an admin-scope zone, you must enable administrative scoping.
Perform the following configuration on all routers in the PIM-SM domain.

Configuring an admin-scope zone boundary
ZBRs form the boundary of each admin-scope zone. 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 you want to configure as a ZBR.

3. Configure a multicast

{ mask | mask-length }
By default, no multicast forwarding
boundary is configured.
The group-address { mask |
mask-length } argument can
specify the multicast groups that an
admin-scope zone serves, in the
range of 239.0.0.0/8.
