DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/0/CPU0:router# configure
Enters global configuration mode.
Step 2
multicast-routing [vrf vrf-name]
[address-family {ipv4 | ipv6}]
Example:
RP/0/0/CPU0:router(config)# multicast-routing
address-family ipv4
Enters multicast routing configuration mode.
• The following multicast processes are started: MRIB,
MFWD, PIM, IGMP, and MLD.
• For IPv4, IGMP version 3 is enabled by default; for
IPv6, MLD version 1 is enabled by default.
Step 3
rate-per-route
Example:
RP/0/0/CPU0:router(config-mcast-default-ipv4)#
rate-per-route
Enables a per (S,G) rate calculation for a particular route.
Step 4
interface {type interface-path-id | all} enable
Example:
RP/0/0/CPU0:router(config-mcast-default-ipv4)#
interface all enable
or
RP/0/0/CPU0:router(config-mcast-default-ipv4)#
interface FastEthernet0/3/3/1 enable
Enables multicast routing on all interfaces.
Step 5
accounting per-prefix
Example:
RP/0/0/CPU0:router(config-mcast-default-ipv)#
accounting per-prefix
• Enables per-prefix counters present in
hardware:accounting per-prefix—Enables three
counters on ingress (forward, punt and drop, and two on
egress (forward and punt) on every existing and new (S,
G) route. The (*, G) routes are assigned a single
counter.
