Configuring C-BSRs for each admin-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.
Perform the following configuration on the routers that you want to configure as C-BSRs in admin-scope
zones.
Follow these steps to configure a C-BSR for an admin-scope zone:

Configure a C-BSR for an
admin-scope zone
c-bsr scope { scope-id | admin-local |
global | organization-local | site-local }
[ hash-length hash-length | priority
priority ] *
Required
No C-BSRs are configured for an
admin-scope zone by default.
NOTE:
You can configure the hash mask length and C-BSR priority globally, only in an IPv6 admin-scope zone,
or both globally and in an IPv6 admin-scope zone.
• The values configured in the IPv6 admin-scope zone have preference over the global values.
• If you do not configure these parameters in the IPv6 admin-scope zone, the corresponding global values
will be used.
For configuration of global C-BSR parameters, see “ Configuring global C-BSR parameters .”
Configuring IPv6 PIM-SSM
NOTE:
The IPv6 PIM-SSM model needs the support of MLDv2. Be sure to enable MLDv2 on IPv6 PIM routers with
receivers attached to them.
