Syntax
ip mroute source-address mask rpf-address preference
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).

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
