maintains a BSR, which serves a specific IPv6 multicast group range. The IPv6 global-scoped zone also
maintains a BSR, which serves the IPv6 multicast groups with the Scope field in the group addresses
being 14.
Enabling IPv6 administrative scoping
Before you configure an IPv6 admin-scoped zone, you must enable IPv6 administrative scoping.
Perform the following configuration on all routers in the IPv6 PIM-SM domain.
To enable IPv6 administrative scoping:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter IPv6 PIM view.
pim ipv6
N/A
3. Enable IPv6 administrative scoping.
c-bsr admin-scope Disabled by default.
Configuring an IPv6 admin-scoped zone boundary
ZBRs form the boundary of each IPv6 admin-scoped zone. Each admin-scoped zone maintains a BSR,
which serves multicast groups with a specific Scope field in their group addresses. 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 IPv6 admin-scoped zone boundary:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type interface-number N/A
3. Configure an IPv6
multicast forwarding
boundary.
multicast ipv6 boundary { ipv6-group-address
prefix-length | scope { scope-id | admin-local |
global | organization-local | site-local } }
By default, no multicast
forwarding boundary is
configured.
Configuring C-BSRs for IPv6 admin-scoped zones
In a network with IPv6 administrative scoping enabled, BSRs are elected from C-BSRs specific to different
Scope field values. 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 IPv6 multicast group.
The following rules apply to the hash mask length and C-BSR priority:
• You can configure these parameters globally and for an IPv6 admin-scoped zone.
• The values of these parameters configured for an IPv6 admin-scoped zone have preference over the
global values.
• If you do not configure these parameters for an IPv6 admin-scoped zone, the corresponding global
values are used.
For configuration of global C-BSR parameters, see "Configuring C-BSR parameters globally."
