The register-stop timer is set to a random value chosen uniformly from the interval (0.5 times 
register_suppression_time, 1.5 times register_suppression_time) minus register_probe_time.  
Configure a filtering rule for register messages on all C-RP routers and configure them to calculate the 
checksum based on the entire register messages. Conf igure the register suppression time and the register 
probe time on all routers that might become source-side DRs.

•   Determine the hash mask length. 
•   Determine the ACL defining the legal BSR address range. 
•   Determine the BS period. 
•   Determine the BS timeout.  
Enabling PIM-SM 
Because BIDIR-PIM is implemented on the basis of PIM-SM, you must enable PIM-SM before enabling 
BIDIR-PIM. To deploy a BIDIR-PIM domain, enable PIM- SM on all non-border interfaces of the domain.  
 
 IMPORTANT: 
On a router, all interfaces in the same VPN instance must operate in the same...

Configuring a C-RP 
In a BIDIR-PIM domain, you can configure routers that int e n d  t o  b e c o m e  t h e  R P  a s  C - R Ps .  T h e  B S R  c o l l e c t s  
the C-RP information by receiving the C-RP-Adv messages from C-RPs or auto-RP announcements 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...

 151 
Each C-RP encapsulates a timeout value in its C-RP-Adv messages. After receiving a C_RP-Adv message, 
the BSR obtains this timeout value and starts a C-RP ti meout timer. If the BSR fails to hear a subsequent 
C-RP-Adv message from the C-RP within the timeout interval, the BSR assumes the C-RP to have expired 
or become unreachable.  
The C-RP timers need to be configured on C-RP routers.  
To configure C-RP timers globally:

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, partition the 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 administrative scoping 
Before you configure...

 154 
All the routers use the same hash algorithm to get the RP address corresponding to the specific multicast 
group.  
Configure C-BSRs for each admin-scope zone and the global-scope zone. 
You can configure the hash mask length and C-BSR priority globally, in an admin-scope zone, and in the 
global scope zone.  
•   The values configured in the global scope zone or admin-scope zone have preference over the 
global values.  
•   If you do not configure these parameters in the global scope zone or...
