Lab 11. OSPF Redistribute – Default Route

Di lab ini kita akan belajar untuk mendistribusikan default route ke semua router. Pada R1 hapus routing eigrp 10 lalu jangan diadvertise ke OSPF karena nantinya akan digunakan untuk pengetesan tes ping menuju route yang tidak terdapat dalam routing tabelnya.

R1:

R1(config)#no router eigrp 10
R1(config)#router ospf 10
R1(config-router)#no redistribute eigrp 10 subnets
R1(config-router)#no area 100 range 100.100.100.0 255.255.255.248
R1(config-router)#default-information originate always
R1(config-router)#exit

R1(config)#

R3:

R3#sh ip route ospf

1.0.0.0/32 is subnetted, 1 subnets

O IA 1.1.1.1 [110/3] via 23.23.23.2, 00:10:50, GigabitEthernet1/0

2.0.0.0/32 is subnetted, 1 subnets

O 2.2.2.2 [110/2] via 23.23.23.2, 00:10:55, GigabitEthernet1/0

12.0.0.0/24 is subnetted, 1 subnets

O IA 12.12.12.0 [110/2] via 23.23.23.2, 00:10:55, GigabitEthernet1/0

100.0.0.0/29 is subnetted, 1 subnets

O IA 100.100.100.0 [110/3] via 23.23.23.2, 00:10:50, GigabitEthernet1/0

R3#sh ip route ospf

Gateway of last resort is 23.23.23.2 to network 0.0.0.0

O*E2 0.0.0.0/0 [110/1] via 23.23.23.2, 00:02:09, FastEthernet1/0

1.0.0.0/32 is subnetted, 1 subnets

O IA 1.1.1.1 [110/3] via 23.23.23.2, 00:05:50, FastEthernet1/0

2.0.0.0/32 is subnetted, 1 subnets

O 2.2.2.2 [110/2] via 23.23.23.2, 00:05:50, FastEthernet1/0

12.0.0.0/24 is subnetted, 1 subnets

O IA 12.12.12.0 [110/2] via 23.23.23.2, 00:05:50, FastEthernet1/0

100.0.0.0/32 is subnetted, 3 subnets

O IA 100.100.100.1 [110/3] via 23.23.23.2, 00:02:23, FastEthernet1/0

O IA 100.100.100.2 [110/3] via 23.23.23.2, 00:02:23, FastEthernet1/0

O IA 100.100.100.3 [110/3] via 23.23.23.2, 00:02:23, FastEthernet1/0

R3:

R3#sh ip route 100.100.100.4

% Subnet not in table

Coba kita cek ping.

R3:

R3#ping 100.100.100.4

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 100.100.100.4, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 40/60/96 ms
