[j-nsp] "low route" with BGP examples?

[dmitri at nominet.org.uk]

Hi Rafal,

This is what I have:

routing-options {
    flow {
        route test-flow-route {
            match source 10.0.0.1/32;
            then discard;
        }
        route test-flow-route-2 {
            match source 10.10.10.0/24;
            then discard;
        }
    }
}
protocols {
    bgp {
        family inet {
            unicast;
            flow;
        }
        group TEST {
            type external;
            description "Test peering with ref-gw";
            multihop {
                ttl 255;
            }
            export iana-reserved;
            peer-as 65002;
            neighbor 192.168.2.2;
            }
        }
    }
}

>show route inetflow.0

inetflow.0: 2 destinations, 2 routes (2 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

*,10.10.10/24/40
                   *[Flow/5] 17:40:51
                      Fictitious
*,10.0.0.1/48
                   *[Flow/5] 22:27:57
                      Fictitious

And still I don't see any flow routes been advertised

>show route advertising-protocol bgp 192.168.2.2 all

inet.0: 15 destinations, 15 routes (11 active, 0 holddown, 4 hidden)
  Prefix                  Nexthop              MED     Lclpref    AS path
* 10.0.0.0/8              Self                                    I
* 169.254.0.0/16          Self                                    I
* 172.16.0.0/12           Self                                    I
* 192.0.2.0/32            Self                                    I


What am I doing wrong?

Dmitri
