Configuring Administrative Scoping - HP 6125G Configuration Manual

Step
1. Enter system view.
2. Enter PIM view.
3. Disable the BSM semantic
fragmentation function.

Configuring administrative scoping

When administrative scoping is disabled, a PIM-SM domain has only one BSR. The BSR manages the
whole network. To manage your network more effectively and specifically, partition the PIM-SM 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 remaining
multicast groups.
Enabling administrative scoping
Before you configure an admin-scope zone, you must enable administrative scoping.
Perform the following configuration on all routers in the PIM-SM domain.
To enable administrative scoping:
Step
1. Enter system view.
2. Enter PIM view.
3. Enable administrative
scoping.
Configuring an admin-scope zone boundary
ZBRs form the boundary of each admin-scope zone. Each admin-scope 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-scope zone boundary.
Perform the following configuration on routers that you want to configure as a ZBR.
To configure an admin-scope zone boundary:
Step
1. Enter system view.
2. Enter interface view.
3. Configure a multicast
forwarding boundary.
