Step Command Remarks
1. Enter system view. system-view N/A
2. Enter public network PIM view. pim N/A
3. Enable administrative scoping. c-bsr admin-scope Disabled by default
2. Configuring an admin-scoped zone boundary
The boundary of each admin-scoped zone is formed by ZBRs. Each admin-scoped 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-scoped zone
boundary.
Perform the following configuration on routers that you want to configure as a ZBR.
To configure an admin-scoped zone boundary:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure a multicast forwarding
boundary. multicast boundary group-address
{ mask | mask-length }
By default, no multicast
forwarding boundary is
configured.
NOTE:
The group-address { mask | mask-length } parameter of the multicast boundary command can be used to
specify the multicast groups an admin-scoped zone serves, in the range of 239.0.0.0/8. For more
information about multicast boundary, see
Network Management Command Reference.
3. 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.
Configure C-BSRs for each admin-scoped zone and the global-scoped zone.

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.
To configure a C-BSR for an admin-scoped zone:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter public network PIM view. pim N/A
3. Configure a C-BSR for an
admin-scoped zone.
c-bsr group group-address { mask |
mask-length } [ hash-length hash-length
| priority priority ] * No C-BSRs are configured
for an admin-scoped zone
by default.
