EIGRP – Filtering – AD
Hapus konfigurasi filtering sebelummya pada R2
R2
R2(config)#no access-list 1 permit 0.0.0.1 255.255.255.254
R2(config)#router eigrp 10
R2(config-router)#no distribute-list 1 in FastEthernet 0/0
Kondisi awal sebelum filtering :
R2
R2(config)#do sh ip route
1.0.0.0/32 is subnetted, 1 subnets
D 1.1.1.1 [90/130816] via 12.12.12.1, 01:17:02, 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, 01:17:02, FastEthernet0/0
D 3.3.3.16/28 [90/156160] via 23.23.23.3, 00:09:09, FastEthernet0/0
D 3.3.3.32/29 [90/156160] via 23.23.23.3, 00:09:09, FastEthernet0/0
D 3.3.3.96/27 [90/156160] via 23.23.23.3, 00:09:09, FastEthernet0/0
D 3.3.3.148/30 [90/156160] via 23.23.23.3, 00:09:09, FastEthernet0/0
D 3.3.3.192/28 [90/156160] via 23.23.23.3, 00:09:09, 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
Konfigurasikan nilai AD yang paling besar yakni 255 pada network 3.3.3.0
R2
R2(config)#access-list 1 permit 3.3.3.0 0.0.0.255
R2(config)#router eigrp 10
R2(config-router)#distance 255 0.0.0.0 255.255.255.255
1 Perintah “3.3.3.0 0.0.0.255” artinya dari IP Address 3.3.3.0 – 3.3.3.255 akan dirubah nilai AD nya menjadi 255 (unreachable).
Cek lagi pada R2
R2#sh ip route
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
Yup ip loopback R1 (1.1.1.1) sudah tidak terdapat lagi dalam routing tabel Router R3.
R1 R1#sh ip route
2.2.2.2 % Network not in table
R1#ping 2.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
