Configuring IPv6 multicast source registration 
Configuration guidelines 
Wi t h i n  a n  I P v 6  P I M - S M  d o m a i n,  t h e  s o u rc e - s i d e  D R  s ends register messages to the RP, and these register 
messages have different IPv6 multicast source or IPv6 multicast group addresses. You can configure a 
filtering rule to filter register messages so that th e RP can serve specific IPv6 multicast groups. If the 
filtering rule denies an (S, G) entry, or if the filtering rule does not...

Disabling SPT switchover 
If an HP 5500 EI switch acts as an RP or the receiver-side DR, it initiates an SPT switchover process by 
default upon receiving the first IPv6 multicast packet along the RPT. You can disable the switchover from 
RPT to SPT. 
 
 IMPORTANT: 
For an HP 5500 EI switch, once an IPv6 multicast forwardin
g entry is created, subsequent IPv6 multicast 
data will not be encapsulated in register messages be
fore being forwarded even if a register outgoing 
interface is available....

Task  Remarks 
Configuring IPv6 PIM common features  Optional. 
 
Configuration prerequisites 
Before you configure IPv6 BIDIR-PIM, complete the following tasks:  
•  Enable IPv6 forwarding and configure an IPv6 unic ast routing protocol so that all devices in the 
domain can communicate with each other at Layer 3. 
•   Determine the IPv6 address of a static RP and the IP v6 ACL that defines the range of IPv6 multicast 
groups to be served by the static RP. 
•   Determine the C-RP priority and the...

Enabling IPv6 BIDIR-PIM 
Perform this configuration on all routers in the IPv6 BIDIR-PIM domain. 
To enable IPv6 BIDIR-PIM: 
 
Step Command Remarks 
1.  Enter system view. 
system-view  N/A 
2.  Enter IPv6 PIM view. 
pim ipv6  N/A 
3.  Enable IPv6 BIDIR-PIM. 
bidir-pim enable  Disabled by default 
 
Configuring an RP 
An RP can be manually configured or dynamically elected through the BSR mechanism. For a large IPv6 
PIM network, static RP configuration is a tedious job. Generally, static RP...

from other routers and organizes the information into an RP-set, which is flooded throughout the entire 
network. Then, the other routers in the network calculate the mappings between specific group ranges 
and the corresponding RPs based on the RP-set. HP recommends that you configure C-RPs on backbone 
routers. 
To guard against C-RP spoofing, configure a legal C-RP address range and the range of multicast groups 
to be served on the BSR. In addition, because every C-BSR has a chance to become...

 370 
Configuring C-RP timers globally 
To enable the BSR to distribute the RP-Set information within the IPv6 BIDIR-PIM domain, C-RPs must 
periodically send C-RP-Adv messages to the BSR. The BSR learns the RP-Set information from the received 
messages, and encapsulates its own IPv6 address togeth er with the RP-Set information in its bootstrap 
messages. The BSR then floods the bootstrap mess ages to all IPv6 routers in the network.  
Each C-RP encapsulates a timeout value in its C-RP -Adv messages....

Configuring an IPv6 BIDIR-PIM domain border 
Perform the following configuration on routers that you want to configure as the IPv6 BIDIR-PIM domain 
border.  
To configure an IPv6 BIDIR-PIM domain border: 
 
Step 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 BIDIR-PIM 
domain border.   pim ipv6 bsr-boundary  By default, no IPv6 BIDIR-PIM 
domain border is configured.

Step Command Remarks 
2.  Enter IPv6 PIM view.

3.  Disable the BSM semantic 
fragmentation function.  undo bsm-fragment

fragmentation function is enabled. 
 
 
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...

 373 
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 
advertisement messages to form an RP-set and advertises  it to all routers in the specific admin-scope zone. 
All the routers use the same hash al gorithm to get the RP address corresponding to the specific multicast 
group.  
You can configure the hash mask...

•  Determine the IPv6 SSM group range. 
Enabling IPv6 PIM-SM 
Configuration guidelines 
The SSM model is implemented based on some subsets  of IPv6 PIM-SM. Therefore, you must enable IPv6 
PIM-SM before configuring IPv6 PIM-SSM.  
When you deploy an IPv6 PIM-SSM domain, enable IPv6  PIM-SM on all non-border interfaces of routers.   
All the interfaces of the same device must operate in the same IPv6 PIM mode.  
Configuration procedure 
To enable IPv6 PIM-SSM:   
Step  Command  Remarks 
1.  Enter...
