[Xorp-users] RIP configuration

[Frederic Gilloteau]

Hello Pavlin,

I had explicitly add the connected policy statement with no success.

My eth0 network is exported very well through RIP, only eth1 does not work.

Any other idea ? :-)

Thanks

Fred

I think you need to explicitly export the connected routes into RIP:

policy {
    /* Describe connected routes for redistribution */
    policy-statement connected {
        term export {
            from {
                protocol: "connected"
            }
        }
    }
}

protocols {
    rip {
        export: "connected"
        ...
    }
}
