H3C S5500-EI - Configuring Ipv6 Administrative Scoping

407
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
provides services for a specific multicast group range. The global scope zone also maintains a BSR,
which provides services for 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 enable IPv6 administrative scoping:
Ste
p
Command Remarks
1. Enter system view.
system-view N/A
2. Enter IPv6 PIM view.
pim ipv6 N/A
3. Enable IPv6 administrative
scoping.
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 provides services for 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.
To configure an admin-scope zone boundary:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure an IPv6 multicast
forwarding boundary.
multicast ipv6 boundary
{ ipv6-group-address prefix-length
| scope { scope-id | admin-local |
global | organization-local |
site-local } }
By default, no IPv6 multicast
forwarding boundary is
configured.

Reference.
Configuring C-BSRs for each admin-scope zone
In a network with administrative scoping enabled, group-range-specific BSRs are elected from C-BSRs.
C-RPs in the network send advertisement messages to the specific BSR. The BSR summarizes the
