DMVPN Lab 5 : Phase 2 Dynamic Mapping

By :

 LAB 5


Topologi LAB.

1. Metode LAB 

• Masih melanjutkan LAB berikutnya, hapus dulu interface tunnel di semua router 

• Hapus routing ospf 12 pada semua router 

• Konfigurasikan dynamic mapping, gunakan perintah ip nhrp nhs pada SPOKE untuk request ke HUB 

• Konfigurasikan MGRE tunneling di semua router

2. Verifikasi : 

- Pastikan type DMVPNnya dynamic, gunakan perintah show ip nhrp / show dmvpn 

- Pastikan di SPOKE ada 2 type map, yaitu static dan dynamic 

3. Konfigurasi 

Lab nya masih lanjut menggunakan topology sebelumnya disini kita hanya perlu hapus tunnel sama routing nya saja.

HUB, Spoke-1, Spoke-2

no router ospf 12 
no interface tunnel 0

Selanjutnya konfigurasikan tunnel baru

HUB

HUB(config)#interface tunnel0 
HUB(config-if)#ip add 192.168.10.1 25 
HUB(config-if)#ip add 192.168.10.1 255.255.255.0 
HUB(config-if)#tunnel mode gre multipoint 
HUB(config-if)#tunnel source 12.12.12.1 
HUB(config-if)#ip nhrp network-id 1 
HUB(config-if)#ip nhrp authentication IDN 
HUB(config-if)#ip nhrp map multicast dynamic

Spoke-1

Spoke-1(config)#int tun0 
Spoke-1(config-if)#ip add 192.168.10.2 255.255.255.0 
Spoke-1(config-if)#tunnel mode gre multipoint 
Spoke-1(config-if)#tunnel source 23.23.23.1 
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 
Spoke1(config-if)#ip nhrp nhs 192.168.10.1 
Spoke-1(config-if)#ip nhrp map multicast 12.12.12.1

Spoke-2

Spoke-2(config)#int tun0 
Spoke-2(config-if)#ip add 192.168.10.3 255.255.255.0 
Spoke-2(config-if)#tunnel mode gre multipoint 
Spoke-2(config-if)#tunnel source 24.24.24.1 
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)#ip nhrp map multicast 12.12.12.1

Lakukan Verifikasi….

HUB#show dmvpn 
Legend: Attrb --> S - Static, D - Dynamic, I - Incomplete 
N - NATed, L - Local, X - No Socket 
 # Ent --> Number of NHRP entries with same NBMA peer

UpDn Time --> Up or Down Time for a Tunnel

Verifikasi NHRP Nya Juga,.

HUB#show ip nhrp
