[R5] ping 10.0.0.1
10.12- rasm. Aloqa natijasi Ping o‗tmadi. Barcha uchta marshrut R5 marshrutlash jadvalida mavjud. BGP to‗g‗ri sozlanganligini bildiradi. Muammoni aniqlash uchun icmp debugging bilan ICMP protokoli bizga yordam beradi. Ko‗rib turganimizdek, R1 icmp echo paketlarini oladi va 5.228.35.5 manziliga javoban echo-javob yuboradi. 5.228.35.0/24 tarmog‗i R1 marshrutlash jadvalida mavjudligini tekshirish uchun ―display ip routing-table‖ buyrug‗idan foydalaniladi. R1 marshrutizatori 5.228.35.0/24 tarmog‗igacha bo‗lgan yo‗lni bilmaydi. Ushbu muammoni hal qilishning ikkita yo‗li mavjud. Eng oddiy yo‗li 5.228.35.0/24 tarmog‗ini bgp protokolida e‘lon qilishdir. Ikkinchi yo‗li marshrutizatorlar o‗rtasida qo‗shimcha IGP protokolini o‗rnatish va barcha kerakli tarmoqlarni e‘lon qilish orqali amalga oshirish mumkin. Bizda birinchi usuldan foydalaniladi. [R5]bgp 5000 [R5-bgp]network 5.228.35.0 24 Yana bir bor ―ping‖ buyrug‗i orqali aloqa tekshiriladi (10.13-rasm). 10.13- rasm. Aloqa natijasi 2-Misol. BGP sinfsiz manzillashni qo‗llab-quvvatlaydi va marshrutlash jadvallarini qisqartirish uchun marshrutni umumlashtirishdan foydalanadi. Bizda to‗rtta avtonom tizim mavjud (10.14- rasm): - AS40 uchta BGP marshutizatorlarini (R2, R3, R4) o‗z ichiga oladi, u AS50, AS60, AS70 bilan EBGP seanslarini o‗rnatadi; - AS50 ikkita marshrutizatorni (R1, R3) o‗z ichiga oladi, ular EBGP seanslarini o‗rnatadi; - AS60 ikkita marshrutizatorni (R1, R4) o‗z ichiga oladi, ular EBGP seanslarini o‗rnatadi; - AS70 faqat bitta marshrutizatorni (R1) o‗z ichiga oladi, ular EBGP seanslarini o‗rnatadi. 10.14- rasm. Tadqiqot qilinayotgan tarmoq topologiyasi Asosiy tizim sozlamalari va IP manzillarni sozlash. R1, R2, R3 va R4 uchun qurilma nomlari va interfeyslarga tarmoq IP manzillari sozlanadi.
