Has pretty good documentary about routing with JunOS. Let this be
example of them, having never configured JunOS I came up with this,
propably not cleverest way and perhaps even non-working, but hopefully
would demostrade a bit.

protocols {
  bgp {
    group foo {
      type external;
      export foo;
      peer-as 42;
      neighbour 10.0.0.2;
    }
  }
}

policy options {
  policy-statement foo {
    term advertise-aggregates {
      from protocol aggregate;
      then accept;
    }
    then {
      reject;
    }
  }
}

routing-options {
  autonomous-system 65500;
  aggregate {
    route 10.100.0.0/16 {
      passive;
    }
  }
}
