DMVPN Lab 10 : Phase 3 Dynamic Mapping With OSPF

 LAB 10

Untuk menjalankan routing OSPF kita hapus kembali routing EIGRP nya dengan command “no router eigrp 12” pada setiap router yang menjalankan EIGRP.

HUB, Spoke-1, Spoke-2

no router eigrp 12

Lalu konfigurasikan OSPF

HUB

HUB(config)#router ospf 12 
HUB(config-router)#network 1.1.1.1 0.0.0.0 area 0 
HUB(config-router)#network 192.168.10.0 0.0.0.255 area 0 
HUB(config-router)#exit 
HUB(config)#int tun0 

HUB(config-if)#ip ospf network broadcast

Spoke-1

Spoke-1(config)#router ospf 12 
Spoke-1(config-router)#network 2.2.2.2 0.0.0.0 area 0 
Spoke-1(config-router)#network 192.168.10.0 0.0.0.255 area 0 
Spoke-1(config-router)#exit Spoke-1(config)#int tun0 

Spoke-1(config-if)#ip ospf network broadcast 

Spoke-2

Spoke-2(config)#router ospf 12 
Spoke-2(config-router)#network 192.168.10.0 0.0.0.255 area 0 
Spoke-2(config-router)#network 3.3.3.3 0.0.0.0 area 0 
Spoke-2(config-router)#exit 
Spoke-2(config)#int tun0 

Spoke-2(config-if)#ip ospf network broadcast

Verifikasi routing OSPF nya

HUB

HUB#show ip route ospf 
 2.0.0.0/32 is subnetted, 1 subnets 
O 2.2.2.2 [110/1001] via 192.168.10.2, 00:01:01, Tunnel0 
 3.0.0.0/32 is subnetted, 1 subnets 

O 3.3.3.3 [110/1001] via 192.168.10.3, 00:00:10, Tunnel0

Spoke-1

Spoke-1#show ip route ospf 
 1.0.0.0/32 is subnetted, 1 subnets 
O 1.1.1.1 [110/1001] via 192.168.10.1, 00:05:59, Tunnel0 
 3.0.0.0/32 is subnetted, 1 subnets 

O 3.3.3.3 [110/1001] via 192.168.10.3, 00:04:59, Tunnel0

Spoke-2

Spoke-2#show ip route ospf 
 1.0.0.0/32 is subnetted, 1 subnets 
O 1.1.1.1 [110/1001] via 192.168.10.1, 00:06:01, Tunnel0 
 2.0.0.0/32 is subnetted, 1 subnets 

O 2.2.2.2 [110/1001] via 192.168.10.2, 00:06:01, Tunnel0

Verfikasi ping ke semua ip loopback

HUB

HUB#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 100 percent (5/5), round-trip min/avg/max = 20/46/72 ms 

HUB#ping 3.3.3.3 
Type escape sequence to abort. 
Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds: 
!!!!! 

Success rate is 100 percent (5/5), round-trip min/avg/max = 44/52/60 ms

Cek Traceroute nya dari spoke ke spoke

Spoke-1

Spoke-1#traceroute 192.168.10.3 
Type escape sequence to abort. Tracing the route to 192.168.10.3 
VRF info: (vrf in name/id, vrf out name/id)

Pada Phase 3 Komunikasi data & routing update dll langsung antar spoke tanpa lewat hub.
