Configuring a multicast router

Unicast routers with more than one interface are automatically configured to start mrouted. If a tunnel is required, create a suitable entry in the file /etc/inet/mrouted.conf and then signal the change to mrouted using the command:

kill -HUP `cat /etc/inet/mrouted.pid`

To configure a multicast router on a host which is not a unicast router:

1. Set the value of the ipforwarding kernel variable to 1 using the following command:
   
   inconfig ipforwarding 1

2. If a tunnel is required, create a suitable entry in the /etc/inet/mrouted.conf file.

3. Add an entry to the file /etc/inet/config to start mrouted at boot time:

   sort-key:/usr/sbin/in.mrouted::y:::
   

4. To start mrouted immediately without rebooting the system, enter:
   
   /usr/sbin/in.mrouted
