merhaba;  

R1=> METRO ETHERNET (Me switch ) > ISP1  

R2 => LL > ISP2   şeklinde çalışan topolojimiz var.  

Isp ler ile Ebgp routerlar kendi aralarında ibgp konuşuyor. daha önce R1 de Me yerine LL vardı . HSRP ile active pasive şekilde çalışıyordu. ancak Me bağlayınca Gigabit eth Me switch ne bağlı olduğundan hat kesilse bile down olmadığından active router standby a düşmüyor normal olarak . aşağıda router ların conflarını yolluyorum . acaba nasıl bir conf değişikliğine gidebilirim .. örnek conflar varsa gönderirmiziniz. yardımlarınız için şimdiden teşekkürler.
