Static-Group command for multiple Multicast IP's??

I am trying to avoid entering 200 "IP IGMP Static-Group 239.x.x.x 10.2.2.2" entries on my Cisco 7600...

Are there any commands available so I can specify a multicast "subnet" to be statically joined to an interface?

I would think cisco has a command similar to my example below(?)...

Example:

ip igmp static-group 239.1.36.0 0.0.0.255 10.25.2.2 ##If this example was a real command, it would allow 239.1.36.1-239.1.36.255(from source 10.2.2.2) to be statically joined to the particular interface.

Re: Static-Group command for multiple Multicast IP's??

To configure the router to be a statically connected member of the specified group on the interface, or to statically forward for a multicast group onto the interface, use the ip igmp static-group command in interface configuration mode. To remove the router as a member of the group, use the no form of this command.

ip igmp static-group {* | group-address [source {source-address | ssm-map}]}

no ip igmp static-group {* | group-address [source {source-address | ssm-map}]}

When you configure the ip igmp static-group command, packets to the group are fast-switched out the interface, provided that packets were received on the correct reverse path forwarding (RPF) interface.

Configuring the ip igmp static-group command is unlike configuring the ip igmp join-group command, which allows the router to join the multicast group. This configuration of the ip igmp static-group command would cause the upstream routers to maintain the multicast routing table information for that group, which would ensure that all the paths to that multicast group are active.
