BGP HELP!!!!!

Hi,

I currently run an ISDN connection and am looking to get a 2MB connection put on.

My problem is that the Block of I addresses I use for all my servers and websites is owned by the isp i got the isdn line off, and the isp providing the 2mb connection is different.

So what I want to do is setup my router (I am using zebra on a linux box to simulate my router) so that all requests will come in through the isdn line and get responded to on the 2mb link.

Now I think this can be done using BGP but I’m not sure how.

Anyone got any Ideas.

Thanks.
Nathan.
