Lab 1. Phase 1 Dynamic Mapping

 

Metode LAB
• Gunakan topologi di atas, konfigurasikan pengalamatan ip standard IDN
• Konfigurasi Default di R1, R2 dan R3
• Konfigurasi MGRE tunnel di HUB dan GRE tunnel di spoke
• Konfigurasikan dynamic mapping, gunakan perintah ip nhrp nhs pada SPOKE untuk request ke HUB

Dalam LAB ini, kita akan mengkonfigurasi :
• HUB menggunakan MGRE tunnel
• SPOKE menggunakan GRE tunnel
• Untuk ip private/tunnel,berikut konfigurasinya :
- R1-HUB = 192.168.100.1/24
- R2-Spoke1 = 192.168.100.2/24
- R3-Spoke2 = 192.168.100.3/24
• Multicast dan unicast hanya di antara HUB dan SPOKE

3. Verifikasi LAB
• Pastikan default route jalan, semua router dapat melakukan ping
• Pastikan HUB mempunyai 2 peers, digunakan perintah showdmvpn

• pastikan ip tunnel sudah benar, gunakan perintah show ip nhrp

Pertama kita konfigurasi dasar pada setiap router.

R1(HUB):
R1(config)#int f0/0
R1(config-if)#ip address 12.12.12.1 255.255.255.0
R1(config-if)#no sh
R1(config-if)#exit
R1(config)#ip route 0.0.0.0 0.0.0.0 12.12.12.2

R3(SPOKE-1):

Spoke-1#config t

Spoke-1(config)#hostname Spoke-1

Spoke-1(config)#int f0/0

Spoke-1(config-if)#ip add 23.23.23.1 255.255.255.0

Spoke-1(config-if)#no shutdown

Spoke-1(config-if)#exit

Spoke-1(config)#ip route 0.0.0.0 0.0.0.0 23.23.23.2

R4(SPOKE-2):

Spoke-2(config)#interface fa0/0

Spoke-2(config-if)#ip add 24.24.24.1 255.255.255.0 Spoke-2(config-if)#no shutdown

Spoke-2(config-if)#exit

Spoke-2(config)#ip route 0.0.0.0 0.0.0.0 24.24.24.2

R2(Internet):

internet(config)#interface fa0/0

internet(config-if)#ip add 12.12.12.2 255.255.255.0

internet(config-if)#no shutdown

internet(config-if)#exit

internet(config)#interface fa1/0

internet(config-if)#ip add 23.23.23.2 255.255.255.0 internet(config-if)#no shutdown

internet(config-if)#exit

internet(config)#interface fa1/1

internet(config-if)#ip add 24.24.24.2 255.255.255.0

internet(config-if)#no shutdown

Coba kita cek ping terlebih dahulu.

R1(HUB):

HUB#ping 23.23.23.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 23.23.23.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 72/98/152 ms

=============================================================

HUB#ping 24.24.24.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 24.24.24.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 40/74/104 ms

Setelah itu kita buat Tunnel pada setiap router (Hub dan Spoke).

R1(HUB):

HUB(config)#interface tunnel0

HUB(config-if)#ip address 192.168.10.1 255.255.255.0

HUB(config-if)#tunnel source 12.12.12.1

HUB(config-if)#tunnel mode gre multipoint

HUB(config-if)#ip nhrp network-id 1

HUB(config-if)#ip nhrp authentication IDN

HUB(config-if)#exit

R3(SPOKE-1):

Spoke-1(config)#interface tunnel0

Spoke-1(config-if)#ip add 192.168.10.2 255.255.255.0

Spoke-1(config-if)#tunnel source 23.23.23.1

Spoke-1(config-if)#tunnel destination 12.12.12.1

Spoke-1(config-if)#ip nhrp network-id 1

Spoke-1(config-if)#ip nhrp authentication IDN

Spoke-1(config-if)#ip nhrp map 192.168.10.1 12.12.12.1

Spoke-1(config-if)#ip nhrp nhs 192.168.10.1

Spoke-1(config-if)#exit

R4(SPOKE-2):

Spoke-2(config)#interface tunnel0

Spoke-2(config-if)#ip add 192.168.10.3 255.255.255.0

Spoke-2(config-if)#tunnel source 24.24.24.1

Spoke-2(config-if)#tunnel destination 12.12.12.1

Spoke-2(config-if)#ip nhrp network-id 1

Spoke-2(config-if)#ip nhrp authentication IDN

Spoke-2(config-if)#ip nhrp map 192.168.10.1 12.12.12.1

Spoke-2(config-if)#ip nhrp nhs 192.168.10.1

Spoke-2(config-if)#exit

Terakhir cek ping kepada antar Tunnel, dan pastikan bisa berkomunikasi :

R1(HUB):

HUB#ping 192.168.10.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.10.2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 36/57/112 ms

========================================================= R1#ping 192.168.10.3

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.10.3, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 16/39/60 ms

OGEH SUDAH BERSYILLL!!!
