[Xorp-users] multicast routing not working -- Sorted

[Dr Ben G Wu]

Hello Bruce,

Centos is mutlicast touting compiled by default. I now get it working.

For those who is interested. I attach my config.boot as below. It is a
very simple sample and I think get use it as a starter.

---------start-----------
interfaces {
     restore-original-config-on-shutdown: false
    interface eth2 {
        description: "vlan2"
        default-system-config
    }
    interface eth1 {
        description: "vlan11"
        default-system-config
    }
}

fea {
     unicast-forwarding4 {
        disable: false
        forwarding-entries {
            retain-on-startup: false
            retain-on-shutdown: false
        }
    }

}
