asaalamualaikum wr.wb
oke to the pointt.. kali ini kita belajar ngonfig lagi yuu ...unttuk materi kali ini kita masih bahas materi eigrp ya...untuk pertama kita buat topology nya dulu kemudian kita tambahkan beberapa ip loopbak
topologi
nah disini kita tambahkan beberapa ip loopbak pada salah satu router saja ...disini saya mengambil sample router R1 yang saya tambahkan 6 ip loopback saya menggunakan ip loopback mulai dari 1.1.1.1 - 1.1.1.6 berikut konfigurasikan nya..(disini saya anggap temen" sudah set konfigurasi dasasr eigrp nya beserta routing eigrp nya, jadi saya mulai dari ip loopback nya )
R1(config-if)#int lo1
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#int lo2
R1(config-if)#ip add 1.1.1.2 255.255.255.255
R1(config-if)#int lo3
R1(config-if)#ip add 1.1.1.3 255.255.255.255
R1(config-if)#int lo4
R1(config-if)#ip add 1.1.1.4 255.255.255.255
R1(config-if)#int lo5
R1(config-if)#ip add 1.1.1.5 255.255.255.255
R1(config-if)#ip add 1.1.1.5 255.255.255.255
R1(config-if)#int lo6
R1(config-if)#ip add 1.1.1.6255.255.255.255
R1(config-if)#ip add 1.1.1.6255.255.255.255
nahh sebelumnya kita cek terlebih dahulu tabel routing pada R2 & R3 nya
R2(config-router)#do sh ip route eigrp

R3(config-if)#do sh ip route eigrp

nah di atas sudah muncul tabel routing dari loopback yang tadi kita buat pada R1..nahh sekarang problem yang akan kita buat yaitu bagaimana si jika kita hanya ingin R2&R3 menapilkan ip ganjil nya saja ..caekidoott guyss berikut konfigurasinya..
R2(config)#access-list 1 permit 0.0.0.1 255.255.255.254
R2(config)#router eigrp 10
R2(config-router)#distribute-list 1 out fa0/1
R2(config-router)#
R2(config)#router eigrp 10
R2(config-router)#distribute-list 1 out fa0/1
R2(config-router)#
nah setelah memasukan perintah tersebut pada R2 untuk pengujian nya kita bisa langsung coba cek tabel routing yang ada pada R3
R3(config-if)#do sh ip route eigrp
1.0.0.0/32 is subnetted, 3 subnets
D 1.1.1.1 [90/158720] via 23.23.23.2, 00:35:34, FastEthernet0/0
D 1.1.1.3 [90/158720] via 23.23.23.2, 00:35:34, FastEthernet0/0
D 1.1.1.5 [90/158720] via 23.23.23.2, 00:35:34, FastEthernet0/0
R3(config-if)#
1.0.0.0/32 is subnetted, 3 subnets
D 1.1.1.1 [90/158720] via 23.23.23.2, 00:35:34, FastEthernet0/0
D 1.1.1.3 [90/158720] via 23.23.23.2, 00:35:34, FastEthernet0/0
D 1.1.1.5 [90/158720] via 23.23.23.2, 00:35:34, FastEthernet0/0
R3(config-if)#
tarraa tabel routing yang muncul pada R3 hanya ip yang ganjil nya saja...sebenernya kita juga bisa sett perintah access-list nya pada R3 juga ..oke kita langsung coba ya..
btw sebelumnya kita hapus dulu konfigurasi access-list pada R2 nya
R2(config-router)#no distribute-list 1 out fa0/1
R2(config-router)#
R2(config-router)#
kemudian kita pastikan tabel routing yang ada pada R3 sudah kembali dengan routingan yang lengkap..
R3(config-if)#do sh ip route eigrp
1.0.0.0/32 is subnetted, 6 subnets
D 1.1.1.1 [90/158720] via 23.23.23.2, 00:40:26, FastEthernet0/0
D 1.1.1.3 [90/158720] via 23.23.23.2, 00:40:26, FastEthernet0/0
D 1.1.1.2 [90/158720] via 23.23.23.2, 00:00:10, FastEthernet0/0
D 1.1.1.5 [90/158720] via 23.23.23.2, 00:40:26, FastEthernet0/0
D 1.1.1.4 [90/158720] via 23.23.23.2, 00:00:10, FastEthernet0/0
D 1.1.1.6 [90/158720] via 23.23.23.2, 00:00:10, FastEthernet0/0
1.0.0.0/32 is subnetted, 6 subnets
D 1.1.1.1 [90/158720] via 23.23.23.2, 00:40:26, FastEthernet0/0
D 1.1.1.3 [90/158720] via 23.23.23.2, 00:40:26, FastEthernet0/0
D 1.1.1.2 [90/158720] via 23.23.23.2, 00:00:10, FastEthernet0/0
D 1.1.1.5 [90/158720] via 23.23.23.2, 00:40:26, FastEthernet0/0
D 1.1.1.4 [90/158720] via 23.23.23.2, 00:00:10, FastEthernet0/0
D 1.1.1.6 [90/158720] via 23.23.23.2, 00:00:10, FastEthernet0/0
nahh jika sudah lengkap mari kita buat access-list yang barunya pada R3..eits sebentar sekarang di router yang R3 kita gunakan distribute-list yang "in" nya ya..
R3(config)#access-list 1 permit 0.0.0.1 255.255.255.254
R3(config)#router eigrp 10
R3(config-router)#distribute-list 1 in fa0/0
R3(config-router)#
R3(config)#router eigrp 10
R3(config-router)#distribute-list 1 in fa0/0
R3(config-router)#
nahh untuk penguujiannya kita coba cek di tabel routing R3
R3(config-router)#do sh ip route eigrp
1.0.0.0/32 is subnetted, 3 subnets
D 1.1.1.1 [90/158720] via 23.23.23.2, 00:46:40, FastEthernet0/0
D 1.1.1.3 [90/158720] via 23.23.23.2, 00:46:40, FastEthernet0/0
D 1.1.1.5 [90/158720] via 23.23.23.2, 00:46:40, FastEthernet0/0
R3(config-router)#
1.0.0.0/32 is subnetted, 3 subnets

D 1.1.1.5 [90/158720] via 23.23.23.2, 00:46:40, FastEthernet0/0
R3(config-router)#
nahh guys gimana perintah nya simple kan....oke untuk hari ini materi nya cukup sampai disini dulu next kita ketemu dengan artikel ip genap nya ya guys....
