Configuring IPv6 administrative scoping
When administrative scoping is disabled, an IPv6 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 IPv6 BIDIR-PIM 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 rest multicast groups.
Enabling IPv6 administrative scoping
Before you configure an IPv6 admin-scope zone, you must enable IPv6 administrative scoping first.
Perform the following configuration on all routers in the IPv6 PIM-SM domain.
To enable IPv6 administrative scoping:

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 serves a specific IPv6 multicast group range. IPv6 multicast 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 an IPv6 multicast
forwarding boundary.

By default, no IPv6 multicast
forwarding boundary is
configured.
