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.
The
group-address
{
mask | mask-length
} parameter of the
multicast boundary
command can be
used to specify the multicast groups an admin-scope zone serves, in the range of 239.0.0.0/8. For
details about the
multicast boundary
command, see
Multicast Routing and Forwarding Commands
in
the
IP Multicast Volume
.
Configuring C-BSRs for each admin-scope zone and the global-scope 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.
Configure C-BSRs for each admin-scope zone and the global-scope zone.
1) Configure C-BSRs for each admin-scope zone
Perform the following configuration on the routers that will work as C-BSRs in admin-scope zones.
