ssm-map (Dynamic IGMP Interface)

Syntax

Hierarchy Level

Description

Apply an SSM map to a dynamic IGMP interface. SSM mapping translates IGMPv1 and IGMPv2 membership reports to an IGMPv3 report, which enables hosts running IGMPv1 or IGMPv2 to participate in SSM. The SSM map associates an SSM policy that matches group addresses to be translated with the source addresses where the group addresses are found.

Starting in Junos OS Release 16.1R5, 16.2R3, 17.1R3, and 17.2R2, the ssm-map statement is deprecated and no longer supported. Starting in Junos OS Release 17.3R1, the statement is removed from the CLI. Use the ssm-map-policy instead to associate the policy with the dynamic IGMP interface for all releases with enhanced subscriber management.

If you upgrade from an earlier release that does not support enhanced subscriber management (any release earlier than Junos OS Release 15.1R4) with a configuration that includes the ssm-map statement, the results vary depending on the release to which you are upgrading:

  • Upgrade to Junos OS Release 16.1R5, 16.2R3, 17.1R3, 17.2R2, or later releases in those branches—The ssm-map configuration is allowed and does not cause the upgrade to fail. However, the configuration has no effect and subscribers cannot log in.

  • Upgrade to Junos OS Release 17.3R1 or later releases—The upgrade fails because the ssm-map configuration is not allowed. If you perform the upgrade without validation (no-validate), the upgrade passes and the ssm-map configuration is accepted, but it has no effect.

Best Practice:

Delete the ssm-map configuration before you upgrade.
