Implementing Multicast Routing on Cisco IOS XR Software
SUMMARY STEPS
1. configure
2. multicast-routing [vrf vrf-name] [address-family {ipv4 | ipv6}]
3. rate-per-route
4. interface {type interface-path-id | all} enable
5. Do one of the following:
6. commit
7. show mfib [vrf vrf-name] [ipv4 | ipv6] route [rate | statistics] [* | source-address] [group-address
[/prefix-length] [detail | old-output] | summary] [location node-id]
DETAILED STEPS
Command or Action
Step 1
configure
Step 2
multicast-routing [vrf vrf-name] [address-family {ipv4
| ipv6}]
Example:
RP/0/RP0/CPU0:router(config)# multicast-routing
address-family ipv4
Step 3
rate-per-route
Example:
RP/0/RP0/CPU0:router(config-mcast-default-ipv4)#
rate-per-route
Step 4
interface {type interface-path-id | all} enable
Example:
RP/0/RP0/CPU0:router(config-mcast-default-ipv4)#
interface all enable
or
RP/0/RP0/CPU0:router(config-mcast-default-ipv4)#
interface FastEthernet0/3/3/1 enable
Step 5
Do one of the following:
• accounting per-prefix
• accounting per-prefix
• accounting per-prefix forward-only
Cisco IOS XR Multicast Configuration Guide for the Cisco CRS Router, Release 5.2.x
Purpose
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.
Enables a per (S,G) rate calculation for a particular route.
Enables multicast routing on all interfaces.
• 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
