DETAILED STEPS
Purpose
Command or Action
configure
Step 1
(Optional) Enters PIM address-family configuration
submode.
router pim
[
address-family
{
ipv4
|
ipv6
}]
Example:
RP/0/RP0/CPU0:router(config)# router pim
Step 2
address-family ipv4
(Optional) Configures the NSF timeout value for multicast
forwarding route entries under the PIM process.
nsf lifetime seconds
Example:
RP/0/RP0/CPU0:router(config-pim-default-ipv4)#
Step 3
If you configure the PIM hello interval to a
nondefault value, configure the PIM NSF lifetime
to a value less than the hello hold time. Typically
the value of the hold-time field is 3.5 times the
interval time value, or 120 seconds if the PIM hello
interval time is 30 seconds.
Note
nsf lifetime 30
(Optional) Exits PIM configuration mode and returns the
router to the source configuration mode.
exit
Example:
RP/0/RP0/CPU0:router(config-pim-default-ipv4)#
Step 4
exit
(Optional) Enters router IGMP configuration mode.
router
{
igmp
| }
Example:
RP/0/RP0/CPU0:router(config)# router igmp
