Hi Alexander,

When using this policy you are doing the following:

-Reject sending default route
-Sending prefix 178.214.192.0/19
-Accepting all other advertisements by BGP it's default behaviour.

I think this would be fine:

show policy-options policy-statement to-MHost
term Itself {
    from {
        protocol static;
        route-filter 178.214.192.0/19 exact;
    }
    then next policy;
}
term reject {
    then reject;
}

Regards,

Tim

policy-options policy-statement to-MHost
term Itself {
    from {
        protocol static;
        route-filter 178.214.192.0/19 exact;
    }
    then accept;
      then
next policy;

}

term reject {

then reject;

}

Hello,

On MX80-48T with JunOS 10.2R1.8 I have a BGP session with downstream
configured as follows:

minot...@br1-gdr.ki# show routing-instances World protocols bgp group 
Downstreams
neighbor 178.214.196.6
description "MHost: World";
import [ Local-Pref-400 from-MHost Deny-Rest ];
export to-MHost;
peer-as 21098;


Filtering of outgoing prefixes is performed via to-MHost policy:
minot...@br1-gdr.ki# show policy-options policy-statement to-MHost
term Default {
     from {
         route-filter 0.0.0.0/0 exact;
     }
     then reject;
}
term Itself {
     from {
         protocol static;
         route-filter 178.214.192.0/19 exact;
     }
     then accept;
}
then accept;


As you can see only route 178.214.192.0/19 from static routes should be
redistributed into BGP, but I see another routes (direct, static, OSPF)
also being redistributed:
minot...@br1-gdr.ki# run show route 178.214.192.0/19 advertising-protocol bgp
178.214.196.6

Why does policy accepts another direct/static/OSPF routes?

Thanks.
