Configuring IPv6 administrative scoping
With IPv6 administrative scoping disabled, an IPv6 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 IPv6 PIM-SM domain into multiple IPv6 admin-scope zones. Each IPv6 admin-scope zone
maintains a BSR, which provides services for a specific IPv6 multicast group range. The IPv6 global
scope zone also maintains a BSR, which provides services for the IPv6 multicast groups with the Scope
field in the group addresses being 14.
Enabling IPv6 administrative scoping
Before you configure an IPv6 admin-scope zone, you must enable IPv6 administrative scoping.
Perform the following configuration on all routers in the IPv6 PIM-SM domain.

Configuring an IPv6 admin-scope zone boundary
The boundary of each IPv6 admin-scope zone is formed by ZBRs. Each admin-scope zone maintains a
BSR, which provides services for multicast groups with a specific Scope field in their group addresses.
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.
