Purpose
Enters global configuration mode.
Enters multicast routing configuration mode.
Enters ipv4 address-family submode.
To configure multicast VPN, you must configure
Note
ipv4 at the core.
Specifies that nonstop forwarding (NSF) maintains the
forwarding state in case of a disruption to a multicast
process.
Specifies the MDT source address.
The MDT source interface is recommended to use
Note
BGP peering update-source interface, however, can
also use another interface in default VRF.
Enables multicast routing and forwarding on all new and
existing interfaces. You can also enable individual
interfaces.
To avoid any possibility of a reverse-path
Caution
forwarding (RPF) failure, you should proactively
enable any interfaces that might possibly carry
multicast traffic.
