Configuring Administrative Scoping - HP A8800 Configuration Manual

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 PIM neighbor is
performed according to the MTU of the outgoing interface.

Configuring administrative scoping

With administrative scoping disabled, a 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
BIDIR-PIM domain into multiple admin-scoped zones. Each admin-scoped zone maintains a BSR, which
serves a specific multicast group range; while the global-scoped zone also maintains a BSR, which
serves all the rest multicast groups.
Enabling administrative scoping
Before configuring an admin-scoped zone, you must enable administrative scoping first.
Perform the following configuration on all routers in the BIDIR-PIM domain.
To enable administrative scoping:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Enable administrative
scoping.
Configuring an admin-scoped zone boundary
The boundary of each admin-scoped zone is formed by ZBRs. Each admin-scoped zone maintains a BSR,
which serves a specific multicast group range. 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 all routers in the BIDIR-PIM domain.
To configure an admin-scoped zone boundary:
Step
1. Enter system view.
2. Enter interface view.
3. Configure a multicast
forwarding boundary.
NOTE:
