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, 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:
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 multicast forwarding
boundary is configured.
For more information about the multicast ipv6 boundary command, see Network Management
Command Reference.
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.
Perform the following configuration on the routers that you want to configure as C-BSRs in IPv6
admin-scoped zones.
To configure a C-BSR for an IPv6 admin-scoped zone:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 PIM view. pim ipv6 N/A
3. Configure a C-BSR for an IPv6
admin-scoped zone.
c-bsr scope { scope-id |
admin-local | global |
organization-local | site-local }
[ hash-length hash-length | priority
priority ] *
No C-BSRs are configured for an
IPv6 admin-scoped zone by
default.
