Configuring an IPv6 admin-scoped zone boundary
The boundary of each IPv6 admin-scoped zone is formed by ZBRs. Each admin-scoped zone maintains
a BSR to provide services for a specific IPv6 multicast group range. IPv6 multicast 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 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 IPv6 multicast
forwarding boundary is
configured.
Configuring C-BSRs for each admin-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 a specific BSR. The BSR summarizes the
advertisement messages to form an RP-set and advertises it to all routers in a specific admin-scoped zone.
All the routers use the same hash algorithm to get the RP address corresponding to a specific multicast
group.
You can configure the hash mask length and C-BSR priority globally, only in an IPv6 admin-scoped zone,
or both globally and in an IPv6 admin-scoped zone.
The values configured in the IPv6 admin-scoped zone have preference over the global values.
If you do not configure these parameters in the IPv6 admin-scoped zone, the corresponding global
values will be used.
For information about how to configure of global C-BSR parameters, see "
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:

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

No C-BSRs are configured for an
admin-scoped zone by default.
