Implementing Multicast Routing on Cisco IOS XR Software

Multicast Configuration Submodes

Cisco IOS XR Software moves control plane CLI configurations to protocol-specific submodes to provide
mechanisms for enabling, disabling, and configuring multicast features on a large number of interfaces.
Cisco IOS XR Software allows you to issue most commands available under submodes as one single command
string from
global configuration
mode.
For example, the ssm command could be executed from the multicast-routing configuration submode like
this:
RP/0/0/CPU0:router(config)#
RP/0/0/CPU0:router(config-mcast-ipv4)#
Alternatively, you could issue the same command from
global configuration
mode like this:
RP/0/0/CPU0:router(config)#
The following multicast protocol-specific submodes are available through these configuration submodes:

Multicast-Routing Configuration Submode

When you issue the multicast-routing ipv4 or multicast-routing ipv6 command, all default multicast
components (PIM, IGMP, MLD, MFWD, and MRIB) are automatically started, and the CLI prompt changes
to "config-mcast-ipv4" or "config-mcast-ipv6", indicating that you have entered multicast-routing configuration
submode.

PIM Configuration Submode

When you issue the router pim command, the CLI prompt changes to "config-pim-ipv4," indicating that you
have entered the default pim address-family configuration submode. To enter pim address-family configuration
submode for IPv6, type the address-family ipv6 keyword together with the router pim command before
pressing Enter.

IGMP Configuration Submode

When you issue the router igmp command, the CLI prompt changes to "config-igmp," indicating that you
have entered IGMP configuration submode.

MLD Configuration Submode

When you issue the router mld command, the CLI prompt changes to "config-mld," indicating that you have
entered MLD configuration submode.
