Ishni bajarish tartibi 14.3- rasmda ko„rsatilgan topologiya bo„yicha qurilmalarni sozlang. 14.3- rasm. Tadqiqot qilinayotgan tarmoq topologiyasi Birinchi navbatda marshrutizator interfeyslari uchun IP manzillar sozlanadi. R5 marshrutizatorini sozlash. tarmoqni quring. R1 da statik NAT ni sozlang. Global IP 48.42.1.5/8 27. 2 ta marshrutizator, 1 ta kommutator, 4 ta ShK dan tashkil topgan tarmoqni quring. R1 da statik NAT ni sozlang. Global IP 58.12.1.5/8 28. 2 ta marshrutizator, 1 ta kommutator, 4 ta ShK dan tashkil topgan tarmoqni quring. R1 da statik NAT ni sozlang. Global IP 68.52.1.7/8 29. 2 ta marshrutizator, 1 ta kommutator, 4 ta ShK dan tashkil topgan tarmoqni quring. R1 da statik NAT ni sozlang. Global IP 38.22.1.6/8 30. 2 ta marshrutizator, 1 ta kommutator, 4 ta ShK dan tashkil topgan tarmoqni quring. R1 da statik NAT ni sozlang. Global IP 48.42.1.8/8 [Huawei]sysname R5 [R5]interface gigabitethernet 0/0/1 [R5-GigabitEthernet0/0/1]ip address 11.11.11.6 8 [R5-GigabitEthernet0/0/1]quit [R5]interface gigabitethernet 0/0/0 [R5-GigabitEthernet0/0/0]ip address 192.168.1.1 24 [R5-GigabitEthernet0/0/0]quit R6 marshrutizatorini sozlash. [Huawei] sysname R6 [R6] interface gigabitethernet 0/0/2 [R6-GigabitEthernet0/0/2]ip address 11.11.11.2 8 [R6-GigabitEthernet0/0/2]quit [R6]interface gigabitethernet 0/0/0 [R6-GigabitEthernet0/0/0]ip address 200.200.200.1 24 [R6-GigabitEthernet0/0/0]quit Endi ikkita marshrutizator o„rtasida statik marshrutizatsiya sozlanadi. R6 marshrutizatorini sozlash. [R6]ip route-static 0.0.0.0 0.0.0.0 11.11.11.6 R5 marshrutizatorini sozlash. [R5]ip route-static 0.0.0.0 0.0.0.0 11.11.11.2 R5 marshrutizatorda statik NAT ni sozlash quyidagicha amalga oshiriladi. [R5-GigabitEthernet0/0/1]nat static global 11.11.11.5 inside 192.168.1.2 netmask 255.255.255.255 [R5-GigabitEthernet0/0/1]nat static global 11.11.11.5 inside 192.168.1.3 netmask 255.255.255.255 Endi PC7 va PC8, Server3 ga IP manzil, maska va shlyuz beriladi. PC7 ga IP, maska va shlyuz berish 14.4- rasmda keltirilgan. 14.4- rasm. PC7 ga IP manzil, maska va shlyuz berish oynasi PC8, Server3 ga ham huddi shu tarzda IP manzil, maska va shlyuz beriladi. NAT sozlamasini ko„rish uchun “display nat static” buyrug„i ishga tushiriladi va natija tekshiriladi (14.5- rasm). 14.5- rasm. Statik NAT natijasi |
