Step
2. Enter public network PIM view
or VPN instance PIM view.
3. Enable administrative
scoping.
Configuring an admin-scoped zone boundary
The boundary of each admin-scoped zone is formed by ZBRs. Each admin-scoped zone maintains a BSR,
which serves a specific multicast group range. 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 admin-scoped zone boundary:
Step
1. Enter system view.
2. Enter interface view.
3. Configure a multicast
forwarding boundary.
Configuring C-BSRs for each admin-scoped zone and the global-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 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
multicast group.
The following rules apply to the hash mask length and C-BSR priority:
You can configure the hash mask length and C-BSR priority globally, for a admin-scoped zone, and
•
for the global-scoped zone.
The values of these parameters configured for the global-scoped zone or an admin-scoped zone
•
have preference over the global values.
If you do not configure these parameters for the global-scoped zone or an admin-scoped zone, the
•
corresponding global values are used.
For configuration of global C-BSR parameters, see
Configure C-BSRs for each admin-scoped zone and the global-scoped zone.
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.
