Implementing Multicast Routing on Cisco IOS XR Software Cisco ASR 9000 Series Routers
Purpose
Enters global configuration mode.
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 multicast routing and forwarding on all new
and existing interfaces.
Exits multicast routing configuration mode, and returns
the router to the source configuration mode.
(Optional) Enters router IGMP or MLD configuration
mode.
(Optional) Selects the IGMP or MLD version that the
router interface uses.
The default for IGMP is version 3; the default for
•
MLD is version 1.
Host receivers must support IGMPv3 for PIM-SSM
•
operation.
If this command is configured in router IGMP or
•
router MLD configuration mode, parameters are
inherited by all new and existing interfaces. You
can override these parameters on individual
interfaces from interface configuration mode.
