Configuring an admin-scope zone boundary
ZBRs form the boundary of each admin-scope zone. 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 you want to configure as a ZBR.

3. Configure a multicast
forwarding boundary.
multicast boundary group-address
{ mask | mask-length }
By default, no multicast forwarding
boundary is configured.
The group-address { mask |
mask-length } argument can
specify the multicast groups that an
admin-scope zone serves, in the
range of 239.0.0.0/8.
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.
The following rules apply to the hash mask length and C-BSR priority:
• You can configure these parameters globally, for an admin-scope zone, and for the global scope
zone.
• The values of these parameters configured for the global scope zone or an admin-scope zone have
preference over the global values.
• If you do not configure these parameters for the global scope zone or an admin-scope zone, the
corresponding global values are used.
For configuration of global C-BSR parameters, see "Configuring global C-BSR parameters."
Configure C-BSRs for each admin-scope zone and the global-scope zone.

Perform the following configuration on the routers that you want to configure as C-BSRs in
admin-scope zones.
