7.2 Basic multicast-group configuration
7.2.1 Start multicast-group route
Start multicast-group route in order to allow D-Link router software transmit multicast-group message.
Under the global configuration catalog input the following command to start multicast-group message
transmission:
Command
ip multicast-routing
Input ip command,clew:
(00) access-list
(15) multicast-routing
......
Please Input the code of command to be excute(0-25): 15
Input 15，select multicast-routing option.
7.2.2 Start multicast-group function on the port
Run multicast-group software on the port will activate IGMP operation. Multicast-group route protocol
include OLNK,PIM-DM,PIM-SM, or DVMRP. On the same port ,it allow the only multicast-group
protocol to run. Using D-Link router to connect some multicast-group domain, it can run different
multicast-group protocol on the different port.
Though D-Link router software could serve as multicast-group boundary router very well, if possible,
please make sure that not run some multicast-group route protocol at the moment, because it will affect
some other protocols. For example, when PIM-DM(only support (S,G) option) and BIDIR PIM-SM(only
support (*,G)option) running, it will lead to confusion.
1. Start OLNK
Running OLNK on the port in order to start multicast-group function. Under the port configuration input
the following command:
Command
ip olnk
In parameter clew choose the 17th option, clew:
00) access-group
......
(13) olnk
......
Please Input the code of command to be excute (0-22): 13
input 11，choose olnk option.
2. Start PIM-DM
Running PIM-DM on the port in order to activate coarctation mode multicast-group function, process as
the following steps:
Command
ip pim-dm
Start multicast-group route
Named access-list
......
Enable IP multicast forwarding
Start multicast-group route
Specify access control for packets
start IGMP only-link on this interface
Come into the port need to run PIM-DM， activate
PIM-DM multicast-group route process under
the port configuration
