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-scoped zone serves, in the
range of 239.0.0.0/8.
Configuring C-BSRs for each admin-scoped zone and the global-scoped 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-scoped
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 the hash mask length and C-BSR priority globally, for a admin-scoped zone, and
for the global scope zone.
• The values of these parameters configured for the global scope zone or an admin-scoped zone
have preference over the global values.
• If you do not configure these parameters for the global scope zone or an admin-scoped 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-scoped zone and the global-scoped zone.
1. Configure C-BSRs for each admin-scoped zone
Perform the following configuration on the routers that you want to configure as C-BSRs in
admin-scoped zones.

3. Configure a C-BSR for an
admin-scoped zone.

No C-BSRs are configured for an
admin-scoped zone by default.
The group-address { mask |
mask-length } argument can
specify the multicast groups that
the C-BSR serves, in the range of
239.0.0.0/8.
2. Configure C-BSRs for the global-scoped zone
Perform the following configuration on the routers that you want to configure as C-BSRs in the
global-scoped zone.
To configure a C-BSR for the global-scoped zone:
