Enabling IPv6 administrative scoping
Before you configure an IPv6 admin-scope zone, you must enable IPv6 administrative scoping first.
Perform the following configuration on all routers in the IPv6 PIM-SM domain.
To do...
1. Enter system view.
2. Enter IPv6 PIM view.
3. Enable IPv6 administrative
scoping.
Configuring an IPv6 admin-scope zone boundary
The boundary of each IPv6 admin-scope zone is formed by ZBRs. Each admin-scope 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-scope zone boundary.
Perform the following configuration on routers that you want to configure as a ZBR.
To do...
1. Enter system view.
Enter interface view.
2.
3. Configure an IPv6 multicast
forwarding boundary.
For more information about the multicast ipv6 boundary command, see IP Multicast Command Reference.
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.
Perform the following configuration on the routers that you want to configure as C-BSRs in IPv6
admin-scope zones.
To do...
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure a C-BSR for an IPv6
admin-scope zone.
