Chapter 43 Ipv4 Multicast Protocol
43-44
1. Enable IGMP Protocol
There are not specific commands for enabling IGMP Protocol on the Layer 3 switch. Enabling any multicast
protocol under corresponding interface will automatically enable IGMP.
Command Explanation
Global Mode
ip dvmrp multicast-routing | ip pim
multicast-routing
To enable global multicast protocol is the
prerequisite to enable IGMP protocol, the “no ip
dvmrp multicast-routing | no ip pim
multicast-routing” commands disable multicast
protocol and IGMP protocol. (Required)
Command Explanation
Interface Configuration Mode
ip dvmrp enable| ip pim
dense-mode | ip pim sparse-mode
Enable IGMP Protocol, the corresponding
commands “no ip dvmrp enable| no ip pim
dense-mode | no ip pim sparse-mode” disable
IGMP Protocol. (Required)
2. Configure IGMP Sub-parameters
（1）Configure IGMP group parameters
1) Configure IGMP group filtering conditions
2) Configure IGMP to join in group
3) Configure IGMP to join in static group
Command Explanation
Interface Configuration Mode
ip igmp access-group {<acl_num |
acl_name>}
no ip igmp access-group
Configure the filtering conditions of the interface
to IGMP group; the “no ip igmp access-group”
command cancels the filtering condition.
ip igmp join-group <A.B.C.D >
no ip igmp join-group <A.B.C.D >
Configure the interface to join in some IGMP
group, the “no ip igmp join-group <A.B.C.D >”
command cancels the join.
ip igmp static-group <A.B.C.D >
no ip igmp static-group <A.B.C.D>
Configure the interface to join in some IGMP
static group; the “no ip igmp static-group
<A.B.C.D >” command cancels the join.
（2）Configure IGMP Query parameters
1) Configure interval for IGMP to send query messages
2) Configure the maximum response time of IGMP query
3) Configure the time-out of IGMP query
