DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/0/CPU0:router# configure
Enters global configuration mode.
Step 2
multicast-routing
Example:
RP/0/0/CPU0:router(config)# multicast-routing
Enters multicast routing configuration mode.
Step 3
address-family ipv4
Example:
RP/0/0/CPU0:router(config-mcast)#
address-family ipv4
Enters ipv4 address-family submode.
Note To configure multicast VPN, you must configure
ipv4 at the core.
Step 4
nsf
Example:
RP/0/0/CPU0:router(config-mcast-default-ipv4)#
nsf
Specifies that nonstop forwarding (NSF) maintains the
forwarding state in case of a disruption to a multicast
process.
Step 5
mdt source type interface-path-id
Example:
RP/0/0/CPU0:router(config-mcast-default-ipv4)#
mdt source GigE 0/1/0/0
Specifies the MDT source address.
Note The MDT source interface is recommended to use
BGP peering update-source interface, however, can
also use another interface in default VRF.
Step 6
interface all enable
Example:
RP/0/0/CPU0:router(config-mcast-default-ipv4)#
interface all enable
Enables multicast routing and forwarding on all new and
existing interfaces. You can also enable individual
interfaces.
Caution To avoid any possibility of a reverse-path
forwarding (RPF) failure, you should proactively
enable any interfaces that might possibly carry
multicast traffic.
