[j-nsp] dsc interface destination unusable as next-hop?

[José Esteves]

Hi,
You must use a policy next-hop self.

Something like this:

policy-options {
    policy-statement next_hop_self {
        from protocol bgp;
        then {
            next-hop self;
        }

Then you must export into your bgp connection.

Hope that helps.

Regards,
JE

Hi,

interfaces {
    dsc {
        unit 0 {
            family inet {
                address 10.66.66.65/32 {
                    destination 10.66.66.66;
                }
            }
        }
    }
}

policy-options {
    policy-statement ingress-processing {
        term blackholing {
            from community blackhole-route;
            then {
                community add no-export;
                next-hop 10.66.66.66;
                accept;
            }
        }
    }
    community blackhole-route members 1:666;
    community no-export members no-export;
}

Any clues why the next-hop is considered unusable? JunOS 6.2R1.5 here.


Best regards,
