Perform the following configuration on routers that you want to configure as a ZBR.
To configure an IPv6 admin-scope zone boundary:
Step Command
Remarks
1.
Enter system view.

2.
Enter interface view.

3.
Configure an IPv6 multicast
forwarding boundary.
multicast ipv6 boundary
{
ipv6-group-address prefix-length
|
scope
{
scope-id

By default, no multicast
forwarding boundary is
configured.
Configuring C-BSRs for IPv6 admin-scope 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-scope zone. All the routers use the same hash algorithm to get the RP address
corresponding to the specific IPv6 multicast group.
The following points apply to the hash mask length and C-BSR priority:
•
You can configure these parameters globally and for an IPv6 admin-scope zone.
•
The values of these parameters configured for an IPv6 admin-scope zone have preference over
the global values.
•
If you do not configure these parameters for an IPv6 admin-scope zone, the corresponding
global values are used.
For configuration of global C-BSR parameters, see "
Configuring C-BSR parameters globally
Perform the following configuration on the routers that you want to configure as C-BSRs in IPv6

No C-BSRs are configured for an

default.
Configuring IPv6 multicast source registration
Within an IPv6 PIM-SM domain, the source-side DR sends register messages to the RP, and these
register messages have different IPv6 multicast source or IPv6 multicast group addresses. You can
configure a filtering rule to filter register messages so that the RP can serve specific IPv6 multicast
groups. If the filtering rule denies an (S, G) entry, or if the filtering rule does not define an action for
this entry, the RP will send a register-stop message to the DR to stop the registration process for the
IPv6 multicast data.
