Lab 2. EIGRP – Filtering – Distribute List
Lab 2. EIGRP – Filtering –
Distribute List
Melanjutkan Lab sebelunya. Jika
kita menginginkan IP Loopback R2 tidak boleh terdapat dalam routing tabel
router R1, maka kita lakukan filtering routenya menggunakan distribute-list.
Sebelumnya kita definisikan dulu network yang akan difilter menggunakan
access-list.

R1 |

R1(config)#access-list 1 deny 2.2.2.2 R1(config)#access-list 1 permit any R1(config)# R1(config)#router eigrp 10 R1(config-router)#distribute-list 1 in g1/0 R1(config-router)#ex R1(config)# |

Selain dikonfigurasikan di
Router R1, kita juga bisa mengkonfigurasikan di Router R2. Namun dengan
direction OUT dengan menghapus terlebih dahulu konfigurasi di Router R1.

R1 |
|
R1(config)#router eigrp 10 R1(config-router)#no distribute-list 1 in g1/0 R1(config-router)# |
Cek routing tabelnya, pastikan
2.2.2.2 muncul kembali
|
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, 00:01:56, GigabitEthernet1/0 3.0.0.0/32 is subnetted, 1 subnets D 3.3.3.3 [90/156416] via 12.12.12.2, 00:06:11, GigabitEthernet1/0 23.0.0.0/24 is subnetted, 1 subnets D 23.23.23.0 [90/28416] via 12.12.12.2, 00:07:56, GigabitEthernet1/0 12.0.0.0/24 is subnetted, 1 subnets C 12.12.12.0 is directly connected, GigabitEthernet1/0 R1(config)# |
Kemudian dilanjutkan
konfigurasi di router R2
