EBGP Routing problem to multiple points

  • 1.  EBGP Routing problem to multiple points

    Hello friends ,

    We have a problem like this and we could not solve it somehow,

    Neighborhood of e-bgp working as an internet service provider,  We announce the ripe ip addresses to 4 operators as ebgp and it works as a full announcement.
    However, 3 operators work smoothly when ebgp neighborhood is set up at the same time.
    but when we connect with an operator, ebgp drops due to prefix limit,

    When we talk to the operator, they tell us that you have received too many route tables from you.

    I want to send only the ip addresses we will use to the operators.
    We send 0.0.0.0/0 as default route.

    Can you review if I send the configs?

    the device we use; Juniper SRX 3600  ver.10


    group SOL-BGP {
    type external;
    traceoptions {
    file SOL_BGP_LOG;
    flag open detail;
    flag state detail;
    flag packets detail;
    flag all;
    }
    local-address X.X.137.2;
    log-updown;
    neighbor X.X.137.1 {
    import SOL_BGP-IMPORT;
    export SOL-BGP-EXPORT;
    peer-as XX984;
    }

    policy-statement SOL_BGP-IMPORT {
    term route {
    from {
    route-filter X.X.101.0/24 exact;   When I use the extract command it doesn't work
    route-filter X.X.103.0/24 exact;   When I use the extract command it doesn't work
    }
    then accept;
    }
    term reject {
    then reject;
    }
    from protocol bgp;



    policy-statement SOL-BGP-EXPORT {
    term default-router {
    from {
    route-filter 0.0.0.0/0 exact;    When I use the extract command it doesn't work
    }
    then accept;
    }
    term reject {
    then reject;
    }
    from protocol bgp;


    what i want to do,
    0.0.0.0/0 default network,
    I don't want it to send any other routes while routing,
