[isp-bgp] BGP on Enterasys 8600

["listabgp" <listabgp@...]

Hello All,

I´m the new network admin of  Avati. Here they have a /20 class.
Today the SSR8600 (enterasys router) is configured like this:

 1 : port set se.8.2 wan-encapsulation ppp speed 2048000

As you can see, we have only one peer with Diveo Backbone, and because this we have a default route: (ip add route default gateway 200.198.88.141 interface serial1)
We are installing a Second backbone and I couldt use default routes anymore.
So I started to test my BGP.
First I remove my default route:
negate 23
save active

As soon I did it my Internet comes down.
So I ask you. Why? I´m using BGP , why my traffic stopped?

There is any error on my confs?
I´m waiting for a answer, because Enterasys support dont have one.
Enterasys runs gated, and my ip-router show configuration-file
shows:

autonomoussystem 10630 ;

                         ;
         };
};

                 ;
         default
                 gateway 200.198.88.141
                 interface "serial1"
                 ;
};
export proto bgp as 15180 {
         proto static {
                 200.162.144.0 mask 255.255.240.0  ;
         };
};
import proto bgp autonomoussystem 15180 {
        0.0.0.0 masklen 0  between 1 and 8  preferen
