BELAJAR EIGRP ( EIGRP Filtering Prefix List -in )

 EIGRP Filtering Prefix List -IN  

Assalamualaikum temen - temen, kembali lagi di blog saya... dan terimakasih telah berkunjung ke blog saya, di blog kali ini saya akan membahas masih seputar EIGRP yaa dan seperti biasa kali ini kita akan membahasnya lebih dalam lagi..

Oke yang sesuai dijudul, di materi kali ini saya akan membahas tentang EIGRP Filtering Prefix List IN, nahhh Pada Filtering Prefix List... kita masih menggunakan IN sama OUT yaa, dan di blogg ini saya akan membahas IN nya dulu.

Filtering menggunakan prefix list digunakan jika kita ingin memfilter berdasarkan netmasknya, misal network pada R3 dengan prefix /24 - /28 akan diblok, selain itu akan ditampilkan

Karena ini adalah blogg lanjutan dari blog tentang EIGRP sebelumnya, jadi saya hanya melakukan konfigurasi yang hanya pada materi kali ini saja, dan untuk teman - teman yang ingin melihat konfigurasi dasarnya... bisa dilihat pada link dibawah ini :

Sekarang di Cek sebelum kita filter prefixnyaaa.....

R2-TKJB#show ip rou

 1.0.0.0/32 is subnetted, 1 subnets

D 1.1.1.1 [90/130816] via 12.12.12.1, 02:40:44, GigabitEthernet1/0

 2.0.0.0/32 is subnetted, 1 subnets

C 2.2.2.2 is directly connected, Loopback0

 3.0.0.0/8 is variably subnetted, 6 subnets, 5 masks

D 3.3.3.3/32  [90/156160] via 23.23.23.3, 03:52:40, FastEthernet0/0

D 3.3.3.16/28 [90/156160] via 23.23.23.3, 00:09:11, FastEthernet0/0

D 3.3.3.32/29 [90/156160] via 23.23.23.3, 00:09:11, FastEthernet0/0

D 3.3.3.96/27 [90/156160] via 23.23.23.3, 00:09:11, FastEthernet0/0

D 3.3.3.148/30 [90/156160] via 23.23.23.3, 00:09:11, FastEthernet0/0

D 3.3.3.192/28 [90/156160] via 23.23.23.3, 00:09:11, FastEthernet0/0

 23.0.0.0/24 is subnetted, 1 subnets

C 23.23.23.0 is directly connected, FastEthernet0/0

 12.0.0.0/24 is subnetted, 1 subnets

C 12.12.12.0 is directly connected, GigabitEthernet1/0

Nah kalo udh dicekk kita bisa mulai konfigurasi prefix list nyaaa...

R2

R2-TKJB(config)#ip prefix-list EIGRP_IN seq 10 deny 3.3.3.0/24 le 28

R2-TKJB(config)#ip prefix-list EIGRP_IN seq 20 permit 0.0.0.0/0 le 32

R2-TKJB(config)#ro

R2-TKJB(config)#router eigrp 10

R2-TKJB(config-router)#distribute-list prefix EIGRP_IN in

R2-TKJB(config-router)#exit

R2-TKJB(config)#

Kita cek tabel routing. Pastikan network 3.3.3.x dengan prefix antara 24 sampai 28 sudah tidak ada. Yang ada hanyalah prefix antara 29 sampai 30.

R2-TKJB#show ip rou

 1.0.0.0/32 is subnetted, 1 subnets

D 1.1.1.1 [90/130816] via 12.12.12.1, 02:54:54, GigabitEthernet1/0

 2.0.0.0/32 is subnetted, 1 subnets

C 2.2.2.2 is directly connected, Loopback0

 3.0.0.0/8 is variably subnetted, 3 subnets, 3 masks

D 3.3.3.3/32 [90/156160] via 23.23.23.3, 02:30:22, FastEthernet0/0

D 3.3.3.32/29 [90/156160] via 23.23.23.3, 00:21:10, FastEthernet0/0

D 3.3.3.148/30 [90/156160] via 23.23.23.3, 00:21:10, FastEthernet0/0

 23.0.0.0/24 is subnetted, 1 subnets

C 23.23.23.0 is directly connected, FastEthernet0/0

 12.0.0.0/24 is subnetted, 1 subnets

C 12.12.12.0 is directly connected, GigabitEthernet1/0

DONE :)
