Day 3 - OSPF Redistribution - EIGRP

Lab kali ini kita akan membahas bagimana cara konfigurasi redistribution EIGRP route pada routing OSPF.

Lab 20 - OSPF Redistribution - EIGRP

 Topologi yang digunakan adalah sbb :


Konfigurasi R1 :

interface Loopback0
 ip address 1.1.1.1 255.255.255.255
!
interface Loopback1
 ip address 100.100.100.1 255.255.255.255
!
interface Loopback2
 ip address 100.100.100.2 255.255.255.255
!
interface Loopback3
 ip address 100.100.100.3 255.255.255.255
!
interface Loopback4
 ip address 100.100.100.4 255.255.255.255
!
interface Serial0/0
 ip address 12.12.12.1 255.255.255.0
!

router ospf 1
 router-id 1.1.1.1
 log-adjacency-changes
 network 1.1.1.1 0.0.0.0 area 0
 network 12.12.12.1 0.0.0.0 area 0

Konfigurasi R2 :

interface Loopback0
 ip address 2.2.2.2 255.255.255.255
!
interface FastEthernet0/0
 ip address 23.23.23.2 255.255.255.0
!
interface Serial0/0
 ip address 12.12.12.2 255.255.255.0
!

router ospf 1
 router-id 2.2.2.2
 log-adjacency-changes
 network 0.0.0.0 255.255.255.255 area 0

Konfigurasi R3 :

interface Loopback0
 ip address 3.3.3.3 255.255.255.255
!
interface FastEthernet0/0
 ip address 23.23.23.3 255.255.255.0
!

router ospf 1
 router-id 3.3.3.3
 log-adjacency-changes
 network 0.0.0.0 255.255.255.255 area 0

Kita cek routing table di R3 :
R3#sh ip route
Gateway of last resort is not set

     1.0.0.0/32 is subnetted, 1 subnets
O       1.1.1.1 [110/75] via 23.23.23.2, 00:13:48, FastEthernet0/0
     2.0.0.0/32 is subnetted, 1 subnets
O       2.2.2.2 [110/11] via 23.23.23.2, 00:13:48, FastEthernet0/0
     3.0.0.0/32 is subnetted, 1 subnets
C       3.3.3.3 is directly connected, Loopback0
     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
O       12.12.12.0 [110/74] via 23.23.23.2, 00:13:48, FastEthernet0/0
 
Terlihat bahwa untuk routing IP Loopback R1 belum ada pada routing table R3.

Sekarang kita akan coba tambahkan advertise EIGRP di R1, kemudian kita redistribute ke dalam routing OSPF.
R1(config)#router eigrp 10
R1(config-router)#no auto-summary
R1(config-router)#network 100.100.100.4 0.0.0.0
R1(config-router)#router ospf 1
R1(config-router)#redistribute eigrp 10 subnets
 
Sekarang kita coba cek lagi routing table di R3 : 
R3#sh ip route
Gateway of last resort is not set

     1.0.0.0/32 is subnetted, 1 subnets
O       1.1.1.1 [110/75] via 23.23.23.2, 00:04:56, FastEthernet0/0
     2.0.0.0/32 is subnetted, 1 subnets
O       2.2.2.2 [110/11] via 23.23.23.2, 00:04:56, FastEthernet0/0
     100.0.0.0/32 is subnetted, 1 subnets
O E2    100.100.100.4 [110/20] via 23.23.23.2, 00:00:03, FastEthernet0/0
     3.0.0.0/32 is subnetted, 1 subnets
C       3.3.3.3 is directly connected, Loopback0
     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
O       12.12.12.0 [110/74] via 23.23.23.2, 00:04:56, FastEthernet0/0


Terlihat bahwa sekarang R3 sudah menerima routing IP 100.100.100.4 via routing OSPF dengan tanda O E2.

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 = 64/86/120 ms


Dan hasil ping test dari R3 ke IP 100.100.100.4 sudah berhasil :)
