DETAILED STEPS
Purpose
Command or Action
configure
Step 1
Enters PIM configuration mode, or PIM address-family
configuration submode.
router pim
[
address-family
{
ipv4
|
ipv6
}]
Example:
RP/0/RP0/CPU0:router(config)# router pim
Step 2
Assigns an RP to multicast groups.
rp-address ip-address
[
group-access-list
] [] [
override
]
Step 3
Example:
RP/0/RP0/CPU0:router(config-pim-default-ipv4)#
•
If you specify a
group-access-list-number
value, you
must configure that access list using the
ipv4 access-list
command.
rp-address 172.16.6.22 rp-access
(Optional) Allows backward compatibility on the RP that
uses old register checksum methodology.
old-register-checksum
Example:
RP/0/RP0/CPU0:router(config-pim-ipv4)#
Step 4
old-register-checksum
Exits PIM configuration mode, and returns the router to the
source configuration mode.
exit
Example:
RP/0/RP0/CPU0:router(config-pim-ipv4)# exit
Step 5
(Optional) Enters access list configuration mode and
configures the RP access list.
{
ipv4
|
ipv6
}
access-list name
Example:
RP/0/RP0/CPU0:router(config)# ipv4 access-list
Step 6
•
The access list called
“
rp-access
”
permits multicast group
239.1.1.0 0.0.255.255.
