Brocade Communications Systems IPMC5000PEF 사용자 설명서

The acl-id/acl-name parameter specifies the ACL id or name used to configure multiple SSM group
ranges.

To disable the SSM mapping range ACL, use the [no] form of this command.

NOTE
The ssm-enable rangeacl-id acl-name or command also supports IPv6 traffic. The ssm-enable
rangeacl-id acl-name or command must be configured under the IPv6 router pim configuration to
support IPv6.

IGMPv2 SSM mapping

The PIM-SSM feature requires all IGMP hosts to send IGMPv3 reports. Where you have an IGMPv2
host, this can create a compatibility problem. In particular, the reports from an IGMPv2 host contain a
Group Multicast Address but do not contain source addresses. The IGMPv3 reports contain both the
Group Multicast Address and one or more source addresses. This feature converts IGMPv2 reports
into IGMPv3 reports through use of the ip igmp ssm-map commands and a properly configured ACL.

The ACL used with this feature filters for the Group Multicast Address. The ACL is then associated
with one or more source addresses using the ip igmp ssm-map command. When the ip igmp ssm-
map enable command is configured, IGMPv3 reports are sent for IGMPv2 hosts.

The following sections describe how to configure the ACL and the ip igmp ssm-map commands to
use the IGMPv2 SSM mapping feature:

•

Configuring an ACL for IGMPv2 SSM mapping

•

Configuring the IGMPv2 SSM Mapping Commands

NOTE
IGMPv2 SSM Mapping is not supported for IGMP static groups.
