ssm-mapping (IGMP view)
Use ssm-mapping to configure IGMP SSM mappings.
Use undo ssm-mapping to remove IGMP SSM mappings.
Syntax
ssm-mapping source-address acl-number
undo ssm-mapping { source-address | all }
Default
IGMP SSM mappings are not configured.
Views
IGMP view
Predefined user roles
network-admin
Parameters
source-address: Specifies a multicast source by its IP address.
acl-number: Specifies a basic ACL number in the range of 2000 to 2999. The specified multicast source
is mapped only to multicast groups that the ACL permits. If the ACL does not exist or the ACL does not
have valid rules, the specified multicast source is not mapped to multicast groups.
all: Removes all the IGMP SSM mappings.
Usage guidelines
In an IPv4 basic ACL, the source keyword matches the multicast group address in IGMP reports.
If you specify the vpn-instance keyword in an ACL rule, the rule does not take effect. The other optional
parameters except the time-range keyword and the fragment keyword in the ACL rules are ignored.
Examples
# Map the multicast source 125.1.1.1 to the multicast groups in the range of 232.1.1.0/24 on the public
network.
