(Optional) Configuring an SSM Group Policy

(Optional) Configuring an SSM Group Policy

Context

By default, the address of a Source-Specific Multicast (SSM) group ranges from 232.0.0.0 to 232.255.255.255. If a user joins a multicast group whose IP address is not in this range, configure an SSM group policy in the VLAN to add the multicast group address to the range of SSM group addresses. The SSM group policy must be used together with an ACL. For details on how to configure an ACL, see "ACL Configuration" in the Huawei AR Series Access Routers Configuration Guide - Security.

NOTE:

By default, the ACL applied to an SSM group policy denies all multicast groups. Therefore, to exclude specific group addresses from the SSM group address range, use a rule permit source any rule with deny rules in the ACL.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    vlan vlan-id

    The VLAN view is displayed.

  3. Run:

    igmp-snooping ssm-policy basic-acl-number

    An SSM group policy is configured.

    After you configure an SSM group policy, the multicast groups specified in the SSM policy are considered as SSM groups.
