interfaces <interface> ip igmp static-group <group> source <source>
Specifies static multicast group membership on an interface.
- interface
- The type of interface. For a list of supported interfaces and detailed syntax, see interfaces <interface> ip igmp.
- group
- The IP multicast address of the group the router is being made a member of.
- source
- The static source of multicast packets. Supported values are:
x.x.x.x : The IP address of a multicast source.
ssm-map : Use Source Specific Multicast (SSM) mapping to determine the multicast source associated with this group.
Configuration mode
interfaces interface {
ip {
igmp {
static-group group
{
source source
}
}
}
}
Use this command to specify static multicast group membership on an interface.
When the multicast group is statically configured on an interface, packets to the group are fast-switched out the interface ensuring all upstream routers maintain routing information for the group.
When the ssm-map keyword is used, the router uses Source Specific Multicast (SSM) mapping to determine the multicast source associated with this group. The resulting (S, G) channels are statically forwarded.
Use the set form of this command to specify static multicast group membership on an interface.
Use the delete form of this command to remove multicast group membership on the interface.
Use the show form of this command to show static group membership configuration.
