SSM Mapping Example

The following configuration example shows a router configuration for SSM mapping. This example also
displays a range of other IGMP and SSM configuration options to show compatibility between features. Do
not use this configuration example as a model unless you understand all of the features used in the example.
Address assignment in the global SSM range 232.0.0.0/8 should be random. If you copy parts or all of
Note
this sample configuration, make sure to select a random address range but not 232.1.1.x as shown in this
example. Using a random address range minimizes the possibility of address collision and may prevent
conflicts when other SSM content is imported while SSM mapping is used.
