DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enters PIM configuration mode, or PIM address-family
configuration submode.
router pim [address-family {ipv4 | ipv6}]
Example:
RP/0/RSP0/CPU0:router(config)# router pim
Step 2
Assigns an RP to multicast groups.
rp-address ip-address [group-access-list] [bidir]
[override]
Step 3
•
If you specify a group-access-list-number value, you
must configure that access list using the ipv4 access-list
command.
Example:
RP/0/RSP0/CPU0:router(config-pim-default-ipv4)#
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/RSP0/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/RSP0/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/RSP0/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.
rp-access
(Optional) Permits multicast group 239.1.1.0 0.0.255.255
for the “rp-access” list.
[sequence-number] permit source [source-wildcard]
Example:
RP/0/RSP0/CPU0:router(config-ipv4-acl)# permit
Step 7
The commands in Step 6, on page 55 and Step 7,
on page 55 can be combined in one command string
like this: ipv4 access-list rp-access permit 239.1.1.0
0.0.255.255.
Tip
