Configuring Ipv6 Administrative Scoping - HP A8800 Configuration Manual

Step
2. Enter IPv6 PIM view.
3. Disable the BSM semantic
fragmentation function.
NOTE:
Generally, a BSR performs BSM semantic fragmentation according to the MTU of its BSR interface.
However, the semantic fragmentation of BSMs originated due to learning of a new IPv6 PIM neighbor is
performed according to the MTU of the outgoing interface.

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, you can
partition the IPv6 PIM-SM domain into multiple IPv6 admin-scoped zones. Each IPv6 admin-scoped zone
maintains a BSR, which serves a specific IPv6 multicast group range; while the IPv6 global-scoped 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 configuring an IPv6 admin-scoped zone, you must enable IPv6 administrative scoping first.
Perform the following configuration on all routers in the IPv6 PIM-SM domain.
To enable IPv6 administrative scoping:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Enable IPv6 administrative
scoping.
Configuring an IPv6 admin-scoped zone boundary
The boundary of each IPv6 admin-scoped zone is formed by ZBRs. Each admin-scoped 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-scoped zone boundary.
Perform the following configuration on routers that you want to configure as a ZBR.
To configure an IPv6 admin-scoped zone boundary:
Step
1. Enter system view.
2. Enter interface view.
