991BConfiguring 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 serves a specific IPv6 multicast group range. The IPv6 global scope zone also
maintains a BSR, which serves the IPv6 multicast groups with the Scope field in the group addresses
being 14.
1800BEnabling 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.

1801BConfiguring an IPv6 admin-scope zone boundary
ZBRs form the boundary of each IPv6 admin-scope zone. Each admin-scope zone maintains a BSR,
which serves 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.

By default, no multicast
forwarding boundary is
configured.
1802BConfiguring C-BSRs for IPv6 admin-scope zones
In a network with IPv6 administrative scoping enabled, BSRs are elected from C-BSRs specific to different
Scope field values. C-RPs in the network send advertisement messages to the specific BSR. The BSR
