DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enters multicast routing configuration mode.
multicast-routing [vrf vrf-name] [address-family {ipv4
| ipv6}]
Step 2
•
The following multicast processes are started: MRIB,
MFWD, PIM, IGMP, and MLD.
Example:
RP/0/RP0/CPU0:router(config)# multicast-routing
•
For IPv4, IGMP version 3 is enabled by default; for IPv6,
MLD version 1 is enabled by default.
address-family ipv4
Enables a per (S,G) rate calculation for a particular route.rate-per-route
Example:
RP/0/RP0/CPU0:router(config-mcast-default-ipv4)#
Step 3
rate-per-route
Enables multicast routing on all interfaces.
interface {type interface-path-id | all} enable
Example:
RP/0/RP0/CPU0:router(config-mcast-default-ipv4)#
Step 4
interface all enable
or
RP/0/RP0/CPU0:router(config-mcast-default-ipv4)#
interface FastEthernet0/3/3/1 enable
