Configuring IPv6 PIM

same priority value and the same hash value, the C-RP with the highest IPv6 address is selected by the
DR.
There may be multiple C-RPs defined for IPv6 in order to support different C-RPs for different zones. A
particular C-RP will unicast the C-RP-Adv messages to the BSR for each scope zone for which it has
state.
Verifying the Changes
Check the maximum number of RPs using the
show ipv6 pim sparse
command. For example:
-> show ipv6 pim sparse
Status = enabled,
Keepalive Period = 210,
Max RPs = 32,
Probe Time = 5,
Register Suppress Timeout = 60,
RP Switchover = enabled,
SPT Status = enabled,
Check C-RP address, priority level, and explicit multicast group information using the
show ipv6 pim
candidate-rp
command:
-> show ipv6 pim candidate-rp
RP Address Group Address Priority Interval Status
------------------+---------------+---------+---------+--------
3000::11 FF00::/8 192 60 enabled
The group address is listed as FF00::/8. The C-RP is listed as 3000::11. The status is enabled.

Configuring Candidate Bootstrap Routers (C-BSRs) for IPv6 PIM
You can use the
ipv6 pim cbsr
command to configure the local router as the candidate-BSR for the IPv6
PIM domain. For example:
-> ipv6 pim cbsr 2000::1 priority 100 mask-length 4
This command specifies the router to use its local address 2000::1 for advertising it as the C-BSR for that
domain, sets the priority value of the local router as a C-BSR to 100, and sets the mask-length that is
advertised in the bootstrap messages to 4. The priority value is used to select a C-BSR for the IPv6 PIM
domain. The higher the value, the higher the priority.
Use the
no
form of this command to remove the local routers' candidacy as the BSR. For example:
-> no ipv6 pim cbsr 2000::1
Verifying the C-BSR Configuration
Check C-BSR and information about priority and mask-length using the
show ipv6 pim cbsr
command,
as follows:
-> show ipv6 pim cbsr
CBSR Address = 3000::7,
Status = enabled,
CBSR Priority = 0,
Hash Mask Length = 126,
