Configuring an RPF Topology in PIM
SUMMARY STEPS
1. configure
2. router pim address-family {ipv4 | ipv6}
3. rpf topology route-policy policy-name
4. exit
5. multicast-routing address family {ipv4 | ipv6}
6. interface all enable
7. end
or
commit
8. show pim [vrf vrf-name] [ipv4 | ipv6] [{unicast | multicast | safi-all} topology {table-name | all}]
rpf [ip-address | hash | summary | route-policy]
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)#
RP/0/0/CPU0:router(config-pim-default-ipv6)#
Enters PIM address-family configuration submode for the
IP prefix you select.
Step 3
rpf topology route-policy policy-name
Example:
RP/0/0/CPU0:router(config-pim-default-ipv6)#
rpf topology route-policy mtpolicy
Assigns a given routing policy to an RPF topology table.
Step 4
exit
Example:
RP/0/0/CPU0:router(config-pim-default-ipv6)#
exit
RP/0/0/CPU0:router(config)#
Exits pim address-family configuration submode and
returns you to global configuration mode.
