DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/0/CPU0:router# configure
Enters global configuration mode.
Step 2
router pim [address-family {ipv4 | ipv6}]
Example:
RP/0/0/CPU0:router(config)# router pim
Enters PIM configuration mode, or PIM address-family
configuration submode.
Step 3
rp-address ip-address [group-access-list]
[bidir] [override]
Example:
RP/0/0/CPU0:router(config-pim-default-ipv4)#
rp-address 172.16.6.22 rp-access
Assigns an RP to multicast groups.
• If you specify a group-access-list-number value, you
must configure that access list using the ipv4
access-list command.
Step 4
old-register-checksum
Example:
RP/0/0/CPU0:router(config-pim-ipv4)#
old-register-checksum
(Optional) Allows backward compatibility on the RP that
uses old register checksum methodology.
Step 5
exit
Example:
RP/0/0/CPU0:router(config-pim-ipv4)# exit
Exits PIM configuration mode, and returns the router to the
source configuration mode.
Step 6
{ipv4 | ipv6} access-list name
Example:
RP/0/0/CPU0:router(config)# ipv4 access-list
rp-access
(Optional) Enters access list configuration mode and
configures the RP access list.
• The access list called “rp-access” permits multicast
group 239.1.1.0 0.0.255.255.
