R3303-HP HSR6800 Routers IP Multicast Configuration Guide
124
The following rules apply to the hash mask length and C-BSR priority:
• You can configure these parameters globally, for an admin-scoped zone, and for the global scope
zone.
• The values of these parameters configured for the global scope zone or an admin-scoped zone
have preference over the global values.
• If you do not configure these parameters for the global scope zone or an admin-scoped zone, the
corresponding global values are used.
For configuration of global C-BSR parameters, see "Configuring global C-BSR parameters."
Configure C-BSRs for each admin-scoped zone and the global-scoped zone.
1. Configure C-BSRs for each admin-scoped zone:
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:
Ste
p
Command
Remarks
1. Enter system view.
system-view N/A
2. Enter public network PIM view
or VPN instance PIM view.
pim [ vpn-instance
vpn-instance-name ]
N/A
3. Configure a C-BSR for an
admin-scoped zone.
c-bsr group group-address { mask |
mask-length } [ hash-length
hash-length | priority priority ] *
No C-BSRs are configured for an
admin-scoped zone by default.
The group-address { mask |
mask-length } argument can
specify the multicast groups that
the C-BSR serves, in the range of
239.0.0.0/8.
2. Configure C-BSRs for the global-scoped zone
Perform the following configuration on the routers that you want to configure as C-BSRs in the
global-scoped zone.
To configure a C-BSR for the global-scoped zone:
Ste

2. Enter public network PIM view

3. Configure a C-BSR for the
global-scoped zone.
c-bsr global [ hash-length
hash-length | priority priority ] *
No C-BSRs are configured for the
global-scoped zone by default.
Configuring multicast source registration
Within a PIM-SM domain, the source-side DR sends register messages to the RP, and these register
messages have different multicast source or group addresses. You can configure a filtering rule to filter
register messages so that the RP can serve specific multicast groups. If the filtering rule denies an (S, G)
entry, or if the filtering rule does not define the action for this entry, the RP will send a register-stop
message to the DR to stop the registration process for the multicast data.
