IP Multicast Commands | 459
The combination of the sourceipaddr and the mask fields specify the network IP address of the 
multicast packet source. The groupipaddr is the IP address of the next hop toward the source. The 
metric is the cost of the route entry for comparison with other routes to the source network and is a 
value in the range of 0 and 255. The current incoming interface is used for RPF checking for 
multicast packets matching this multicast static route entry.
The no ip multicast staticroute sourceipaddr command deletes a static route in the static mcast 
table. The sourceipaddr is the IP address of the multicast packet source.
