Şu anda uyguladığım durum BGP peerlarım için aspath prepend uygulamak oluyor.Ama tabii bu ISP 'lerden bana erisimi etkiliyor.Gelen trafik geri giderken benim default devremi kullanıyor. Yakın ISP'ler için gelen ve giden trafiği BGP de nasıl yonlendirebilirim.Internette ornekleme bulamadım.Şu anki bgp konfigrasyonuma ait örnek aşağıdadır.Fikirlerinizi rica ediyorum.
