Configuring Ipv6 Administrative Scoping - HP A6600 Configuration Manual

To do...
1. Enter system view.
2. Enter IPv6 PIM view.
3. Disable the BSM semantic
fragmentation function.
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 PIM neighbor is
performed according to the MTU of the outgoing interface.

Configuring IPv6 administrative scoping

With administrative scoping disabled, an IPv6 BIDIR-PIM domain has only one BSR. The BSR manages the
whole network. To manage your network more effectively and specifically, you can partition the IPv6
BIDIR-PIM domain into multiple admin-scope zones. Each admin-scope zone maintains a BSR, which
serves a specific multicast group range. The global scope zone also maintains a BSR, which serves all the
rest multicast groups.
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 a specific IPv6 multicast group range. IPv6 multicast 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.
Follow these steps to configure an admin-scope zone boundary:
To do...
1. Enter system view.
2. Enter interface view.
3. Configure an IPv6 multicast
forwarding boundary.
For more information about the multicast ipv6 boundary command, see IP Multicast Command Reference.
