Lab 29. EIGRP - Filtering - Distribute List
Tujuan Lab :
- Belajar melakukan filtering router pada EIGRP menggunakan perintah distribute-list
Topologi Lab :
Metode Lab :
- Konfigurasi pengalamatan IP standar untuk topologi di atas
- Menggunakan topologi dan konfigurasi EIGRP sebelumnya
- Konfigurasi distribute-list terhadap loopback Router R2 2.2.2.2/32 di Router R1
Verifikasi Lab :
- Pastikan loopback 2.2.2.2 tidak lagi terdapat dalam tabel routing tabel Router R1
Konfigurasi :
Router R1
Sebelumnya saya akan verifikasi terlebih dahulu tabel routing pada Router 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 [90/2297856] via 12.12.12.2, 00:00:26, Serial0/0
3.0.0.0/32 is subnetted, 1 subnets
D 3.3.3.3 [90/2323456] via 12.12.12.2, 00:07:27, Serial0/0
23.0.0.0/24 is subnetted, 1 subnets
D 23.23.23.0 [90/2195456] via 12.12.12.2, 00:07:27, Serial0/0
12.0.0.0/24 is subnetted, 1 subnets
C 12.12.12.0 is directly connected, Serial0/0
Kita dapat melihat pada tabel routing di atas IP loopback 2.2.2.2 masih ada. Selanjutnya kita konfigurasi distribute-list pada Router 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 s0/0
Kemudian cek di routing tabelnya dan pastikan IP 2.2.2.2 sudah tidak lagi terdapat di dalam routing tabelnya.
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 [90/2323456] via 12.12.12.2, 00:14:00, Serial0/0
23.0.0.0/24 is subnetted, 1 subnets
D 23.23.23.0 [90/2195456] via 12.12.12.2, 00:14:00, Serial0/0
12.0.0.0/24 is subnetted, 1 subnets
C 12.12.12.0 is directly connected, Serial0/0
Selain dikonfigurasikan di Router R1, bisa juga dikonfigurasikan di Router R2 namun dengan direction out. Pertama kita hapus terlebih dahulu konfigurasi distribute-list di Router R1 dan kemudian cek routing tabelnya.
R1(config)#router eigrp 10
R1(config-router)#no distribute-list 1 in s0/0
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 [90/2297856] via 12.12.12.2, 00:02:21, Serial0/0
3.0.0.0/32 is subnetted, 1 subnets
D 3.3.3.3 [90/2323456] via 12.12.12.2, 00:20:40, Serial0/0
23.0.0.0/24 is subnetted, 1 subnets
D 23.23.23.0 [90/2195456] via 12.12.12.2, 00:20:40, Serial0/0
12.0.0.0/24 is subnetted, 1 subnets
C 12.12.12.0 is directly connected, Serial0/0
Dapat kita lihat IP loopback 2.2.2.2 muncul kembali. Berikutnya kita konfigurasi di Router R2.
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 [90/2297856] via 12.12.12.2, 00:00:26, Serial0/0
3.0.0.0/32 is subnetted, 1 subnets
D 3.3.3.3 [90/2323456] via 12.12.12.2, 00:07:27, Serial0/0
23.0.0.0/24 is subnetted, 1 subnets
D 23.23.23.0 [90/2195456] via 12.12.12.2, 00:07:27, Serial0/0
12.0.0.0/24 is subnetted, 1 subnets
C 12.12.12.0 is directly connected, Serial0/0
Kita dapat melihat pada tabel routing di atas IP loopback 2.2.2.2 masih ada. Selanjutnya kita konfigurasi distribute-list pada Router 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 s0/0
Kemudian cek di routing tabelnya dan pastikan IP 2.2.2.2 sudah tidak lagi terdapat di dalam routing tabelnya.
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 [90/2323456] via 12.12.12.2, 00:14:00, Serial0/0
23.0.0.0/24 is subnetted, 1 subnets
D 23.23.23.0 [90/2195456] via 12.12.12.2, 00:14:00, Serial0/0

12.0.0.0/24 is subnetted, 1 subnets
C 12.12.12.0 is directly connected, Serial0/0
Dapat kita lihat IP loopback 2.2.2.2 muncul kembali. Berikutnya kita konfigurasi di Router R2.
Router 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 s0/0
Cek kembali routing tabelnya pada Router 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 [90/2323456] via 12.12.12.2, 00:25:21, Serial0/0
23.0.0.0/24 is subnetted, 1 subnets
D 23.23.23.0 [90/2195456] via 12.12.12.2, 00:25:21, Serial0/0
12.0.0.0/24 is subnetted, 1 subnets
C 12.12.12.0 is directly connected, Serial0/0
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 s0/0
Cek kembali routing tabelnya pada Router 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 [90/2323456] via 12.12.12.2, 00:25:21, Serial0/0
23.0.0.0/24 is subnetted, 1 subnets
D 23.23.23.0 [90/2195456] via 12.12.12.2, 00:25:21, Serial0/0
12.0.0.0/24 is subnetted, 1 subnets
C 12.12.12.0 is directly connected, Serial0/0
Dan dapat kita lihat hasilnya IP loopback 2.2.2.2 sudah tidak lagi terdapat dalam tabel routing.
