Cisco | eBGP - Router Reflector

 

BGP Reflector adalah suatu router dijadikan sebagai pusat peer semua router iBGP. ROuter tidak lgi neighbor kesemua router yg lain, melainkan cukup peer sutu router pusat saja. Tugas router reflector adalah menerima informasi update routing dari peer, ketikan router refeltor menerima informasi update darirouter client, mk router RR tersebut akan mengirimkan informasi ke router lainnya.
