Configuring an MLD SSM Translation

Configuring an MLD SSM Translation
You can configure an SSM translation to provide SSM support when the router receives MLDv1 listener
reports. Only MLDv2 provides the capability to specify group and source addresses in listener reports. By
default, the group prefix range is FF3x/96. To modify the PIM SSM range, see Configuring SSM.
Table 9: Example SSM Translations
Group Prefix
FF30::0/16
FF30::0/16
FF30:30::0/24
FF32:40::0/24
This table shows the resulting M6RIB routes that the MLD process creates when it applies an SSM translation
to the MLD v1 listener report. If more than one translation applies, the router creates the (S, G) state for each
translation.

listener report.
