To disable the BSM semantic fragmentation function:

Remarks
1. Enter system view.

2. Enter IPv6 PIM view. pim ipv6 N/A
3. Disable the BSM semantic
fragmentation function.
undo bsm-fragment enable
By default, the BSM semantic
fragmentation function is enabled.
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-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 first.
Perform the following configuration on all routers in the IPv6 PIM-SM domain.

2. Enter IPv6 PIM view.

3. Enable IPv6 administrative

c-bsr admin-scope Disabled by default.
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.
