LAB 2. EIGRP – FILTERING – DISTRIBUTE LIST

 

LAB 2. EIGRP – FILTERING – DISTRIBUTE LIST

Digunakan untuk memfilter network berdasarkan route network yang masuk dan keluar interface. Pada topologi dibawah, tujuannya agar ip loopback 2.2.2.2 tidak ada dalam routing tabel R1.

pertama : filter network menggunakan access list pada R1 dengan distribute IN. Pada lab ini, kita masih menggunakan lab sebelumnya.

R1

R1(config)#access-list 1 deny 2.2.2.2 R1(config)#access-list 1 permit any ! R1(config)#router eigrp 10 R1(config-router)#distribute-list 1 in gigabitEthernet 1/0 R1(config-router)#exit

Kemudian cek pada routing tabelnya. Pastikan IP 2.2.2.2 sudah tidak lagi terdapat dalam routing tabelnya.

R1

R1#sh ip route 1.0.0.0/32 is subnetted, 1 subnets C 1.1.1.1 is directly connected, Loopback0 3.0.0.0/32 is subnetted, 1 subnets D 3.3.3.3 [90/156416] via 12.12.12.2, 02:18:03, GigabitEthernet1/0 23.0.0.0/24 is subnetted, 1 subnets D 23.23.23.0 [90/28416] via 12.12.12.2, 02:07:32, GigabitEthernet1/0 12.0.0.0/24 is subnetted, 1 subnets C 12.12.12.0 is directly connected, GigabitEthernet1/0

kedua : filter network menggunakan access list pada R2 dengan distribute OUT. Kita hapus terlebih dahulu konfigurasi distribute IN.

R1(config)#router eigrp 10 R1(config-router)#no distribute-list 1 in GigabitEthernet 1/0

 

Pastikan ip loopback 2.2.2.2 sudah muncul lagi dalam table routing R1

 

 

R1

R1#sh ip route 1.0.0.0/32 is subnetted, 1 subnets C 1.1.1.1 is directly connected, Loopback0 2.0.0.0/32 is subnetted, 1 subnets D 2.2.2.2 [90/130816] via 12.12.12.2, 02:12:05, GigabitEthernet1/0 3.0.0.0/32 is subnetted, 1 subnets D 3.3.3.3 [90/156416] via 12.12.12.2, 02:26:50, GigabitEthernet1/0 23.0.0.0/24 is subnetted, 1 subnets D 23.23.23.0 [90/28416] via 12.12.12.2, 02:32:54, GigabitEthernet1/0 12.0.0.0/24 is subnetted, 1 subnets C 12.12.12.0 is directly connected, GigabitEthernet1/0

Pada R2 ketik perintah berikut

R2

R2(config)#access-list 1 deny 2.2.2.2 R2(config)#access-list 1 permit any R2(config)#router eigrp 10 R2(config-router)#distribute-list 1 out GigabitEthernet 1/0

 

Maka IP loopback 2.2.2.2 sudah tidak ada

R1

R1#sh ip route 1.0.0.0/32 is subnetted, 1 subnets C 1.1.1.1 is directly connected, Loopback0 3.0.0.0/32 is subnetted, 1 subnets D 3.3.3.3 [90/156416] via 12.12.12.2, 00:56:19, GigabitEthernet1/0 23.0.0.0/24 is subnetted, 1 subnets D 23.23.23.0 [90/28416] via 12.12.12.2, 00:45:03, GigabitEthernet1/0 12.0.0.0/24 is subnetted, 1 subnets C 12.12.12.0 is directly connected, GigabitEthernet1/0
