RP/0/RP0/CPU0:router(config)#
Step 2
RP/0/RP0/CPU0:router(config-pim-default-ipv4)#
Assigns a given routing policy to an RPF
topology table.
rpf topology route-policy policy-name
Example:
RP/0/RP0/CPU0:router(config-pim-default-ipv4)# rpf
Step 3
topology route-policy mtpolicy
Exits pim address-family configuration
submode.
exit
Example:
RP/0/RP0/CPU0:router(config-pim-default-ipv4)# exit
Step 4
RP/0/RP0/CPU0:router(config)#
Enters multicast address-family configuration
submode.
multicast-routing address-family
{
ipv4
|
ipv6
}
Example:
RP/0/RP0/CPU0:router(config)# multicast-routing
Step 5
address-family ipv44
Enables multicast routing and forwarding on
all new and existing interfaces.
interface all enable
Example:
RP/0/RP0/CPU0:router(config-mcast-default- ipv4)4)#
Step 6
interface all enable

show pim [vrf vrf-name
] [
ipv4
|
ipv6
] [{
unicast
|
multicast
|
safi-all
}
topology
{
table-name
|
all
}]
rpf
[
ip-address
|
hash
|
summary
