Layer 3 Routing Commands 1615
no ip mroute source-address mask
• source-address — The IP address of the multicast data source.
• mask — The IP subnet mask of the multicast data source.
• rpf-address — The IP address of the next hop towards the source.
• preference — The cost of the route (Range: 1 - 255).
Default Configuration
There is no default configuration for this command.
Command Mode
Global Configuration mode
User Guidelines
The source IP address must contain 0's for the address bits corresponding to
0's in the netmask.
Multicast source data is flooded/forwarded by default in the VLAN on which
it is received. For this reason, multi-access VLANs are not recommended for
multicast routing interfaces.
Example
console(config)#ip mroute 1.1.0.0 255.255.0.0 192.168.20.1 34
ip multicast-routing
Use the ip multicast-routing command in Global Configuration mode to set
the administrative mode of the IP multicast forwarder in the router to active.
It enables both IPv4 and IPv6 multicast routing. For multicast routing to
become operational, IGMP must be currently enabled. Enabling PIM or
DVMRP enables IGMP.
