3. Enable administrative scoping.
c-bsr admin-scope Disabled by default.
2. 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 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.
NOTE:
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 more
information about multicast boundary, see
Network Management Command Reference
.
3. 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.
