Configuring Ipv6 Administrative Scoping - HP A5500 SI Switch Series Configuration Manual

Configuring IPv6 administrative scoping

With IPv6 administrative scoping disabled, an IPv6 PIM-SM domain has only one BSR. The BSR
manages the whole network. To manage your network more effectively and specifically, partition the
IPv6 PIM-SM domain into multiple IPv6 admin-scope zones. Each IPv6 admin-scope zone maintains a
BSR, which serves a specific IPv6 multicast group range. The IPv6 global scope zone also maintains a
BSR, which serves the IPv6 multicast groups with the Scope field in the group addresses being 14.
Enabling IPv6 administrative scoping
Before you configure an IPv6 admin-scope zone, you must enable IPv6 administrative scoping.
Perform the following configuration on routers that can become a C-BSR and ZBR.
Follow these steps to enable IPv6 administrative scoping:
To do...
Enter system view
Enter IPv6 PIM view
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 can become a ZBR.
Follow these steps to configure an IPv6 admin-scope zone boundary:
To do...
Enter system view
Enter interface view
Configure an IPv6 multicast
forwarding boundary

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
