Configuring an admin-scope zone boundary
The boundary of each admin-scope zone is formed by ZBRs. 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 can become a ZBR.
Follow these steps to configure an admin-scope zone boundary:

Required
By default, no multicast forwarding
boundary is configured.
For details about the multicast boundary command, see Multicast Routing and Forwarding
Commands in the IP Multicast Volume.
Configuring a C-BSR for each zone
In a network with administrative scoping enabled, group-range-specific BSRs are elected from C-BSRs.
C-RPs in the network send advertisement messages to the specific BSR. The BSR summarizes the
advertisement messages to form an RP-set and advertises it to all routers in the specific admin-scope
zone. All the routers use the same Hash algorithm to get the RP address corresponding to the specific
multicast group.
Perform the following configuration on the routers that may become C-BSRs in each admin-scope zone
or the global scope zone.
