Lab 11. OSPF - Filtering Route Administrative

Kali ini kita akan memfilter dengan menggunakn AD dengan cara mengubah nilai AD menjadi 255.
kita hapus terlebih dahulu konfigurasi pada lab sebelumnya :

R2(config)#router ospf 2
R2(config-router)#no distribute-list 1 in

lanjut cek table routing apakah sudah normal :

R2(config)#do sh ip route
1.0.0.0/32 is subnetted, 1 subnets
O 1.1.1.1 [110/11] via 12.12.12.1, 00:00:05, Ethernet0/0
2.0.0.0/32 is subnetted, 1 subnets
C 2.2.2.2 is directly connected, Loopback0
3.0.0.0/32 is subnetted, 1 subnets
O 3.3.3.3 [110/11] via 23.23.23.3, 00:00:05, Ethernet0/1
10.0.0.0/32 is subnetted, 6 subnets
O IA 10.10.10.1 [110/11] via 12.12.12.1, 00:00:05, Ethernet0/0
O IA 10.10.10.2 [110/11] via 12.12.12.1, 00:00:05, Ethernet0/0
O IA 10.10.10.3 [110/11] via 12.12.12.1, 00:00:05, Ethernet0/0
O IA 10.10.10.4 [110/11] via 12.12.12.1, 00:00:05, Ethernet0/0
O IA 10.10.10.5 [110/11] via 12.12.12.1, 00:00:05, Ethernet0/0
O IA 10.10.10.6 [110/11] via 12.12.12.1, 00:00:05, Ethernet0/0
12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 12.12.12.0/24 is directly connected, Ethernet0/0
L 12.12.12.2/32 is directly connected, Ethernet0/0
23.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 23.23.23.0/24 is directly connected, Ethernet0/1
L 23.23.23.2/32 is directly connected, Ethernet0/1

Konfigurasikan filtering dengan AD

R2(config)#access-list 2 permit 10.10.10.4
R2(config)#router ospf 2
R2(config-router)#distance 255 0.0.0.0 255.255.255.255 2

Cek table routing dan pastikan ip 10.10.10.4 tidak ada pada routing table nya

R2(config-router)#do sh ip route
1.0.0.0/32 is subnetted, 1 subnets
O 1.1.1.1 [110/11] via 12.12.12.1, 00:00:16, Ethernet0/0
2.0.0.0/32 is subnetted, 1 subnets
C 2.2.2.2 is directly connected, Loopback0
3.0.0.0/32 is subnetted, 1 subnets
O 3.3.3.3 [110/11] via 23.23.23.3, 00:00:16, Ethernet0/1
10.0.0.0/32 is subnetted, 5 subnets
O IA 10.10.10.1 [110/11] via 12.12.12.1, 00:00:16, Ethernet0/0
O IA 10.10.10.2 [110/11] via 12.12.12.1, 00:00:16, Ethernet0/0
O IA 10.10.10.3 [110/11] via 12.12.12.1, 00:00:16, Ethernet0/0
O IA 10.10.10.5 [110/11] via 12.12.12.1, 00:00:16, Ethernet0/0
O IA 10.10.10.6 [110/11] via 12.12.12.1, 00:00:16, Ethernet0/0
12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 12.12.12.0/24 is directly connected, Ethernet0/0
L 12.12.12.2/32 is directly connected, Ethernet0/0
23.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 23.23.23.0/24 is directly connected, Ethernet0/1
L 23.23.23.2/32 is directly connected, Ethernet0/1

ip 10.10.10.4 sudah tidak ada.
