Cisco: Static Routing Sedehana

R1:

Ethernet1/1 - ke Internet
Ethernet1/2 - R2: Ethernet 1/1
Ethernet1/3 - LAN

R2:

Ethernet1/1 - R1: Ethernet1/2
Ethernet1/2 - LAN

R1:

enable
configure terminal
  interface ethernet1/1
    ! ip address 10.1.1.2 255.255.255.0
    ip address dhcp
    no shutdown
    exit
  interface ethernet1/2
    ip address 172.16.1.1 255.255.255.252
    no shutdown
    exit
  interface ethernet1/3
    ip address 192.168.1.1 255.255.255.0
    exit
  ip route 192.168.2.0 255.255.255.0 172.16.1.2
  exit
copy running-config startup-config

R2:

enable
config terminal
   interface ethernet1/1
    ip address 172.16.1.2 255.255.255.252
    no shutdown
    exit
  interface ethernet1/2
    ip address 192.168.2.1 255.255.255.0
    exit
  ip route 192.168.1.0 255.255.255.0 172.16.1.1
  ip route 0.0.0.0 0.0.0.0 172.16.1.1
  exit
copy running-config startup-config

Request DHCP

enable
config terminal
  interface ethernet1/1
    ip dhcp client request
    exit
  exit

Test

R1:

ping 192.168.2.1

R2:

ping 192.168.1.1

Tambahan Kalau Membutuhkan NAT

Menggunakan NAT untuk Memungkinkan Pengguna Internal Mengakses Internet

Jalankan langkah ini untuk memungkinkan pengguna internal anda mengakses Internet dan menyimpan alamat di kumpulan alamat global di dalam menggunakan kelebihan alamat global.

SUMMARY STEPS

enable
configure terminal
ip nat pool name start-ip end-ip {netmask netmask | prefix-length prefix-length }
access-list access-list-number permit source [source-wildcard ]
ip nat inside source list access-list-number pool name overload
interface type number
ip address ip-address mask
ip nat inside
exit
interface type number
ip address ip-address mask
ip nat outside
end

R1:

enable
configure terminal
ip nat pool net-168.1 192.168.1.1 192.168.1.254 netmask 255.255.255.0
access-list 1 permit 192.168.1.0 0.0.0.255
ip nat inside source list 1 pool net-168.1 overload
interface ethernet1/3
! ip address 192.168.1.1 255.255.255.0
ip nat inside
exit
interface ethernet1/1
! ip address 10.10.0.1 255.255.255.0
! ip address dhcp
ip nat outside
end
