Hi All,

                 Any one can help me using static route in BGP. I have a two isp connected in one router and giving connectivity to my remote location. I had configured one ISP as priamry by Route Map preferece and so failover is working fine. I want to configure a static default route at my client location so that when my primary link is up my all internet traffic must come through my secondary link and i tried the same but it didn't work can any help me in this ??

Thanks in advance

Hi Sandeep,

Your requirement is not so clear to me. I guess you want to utilize the backup ISP link for incoming traffic to your client location.

All inbound traffic depends upon your BGP network advertisements.

So, you need to have a dedicated Public registered network (/24 at minimum) assigned to your remote location so that you can advertise this network through backup AS with higher preference (like no AS-path prepend through backup ISP and AS path prepend for the same network through primary ISP). Please note that advertising /24 network will not work if any upperstream ISPs are aggregating the customer routes to reduce the entries in BGP database but I have seen /24 subnets as well in BGP routes from several providers.
