Lab 5. Phase 2 Dynamic Mapping

 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.

R1,R3,R4:
no router ospf 12

no interface tunnel 0

Selanjutnya kita akan konfigurasikan tunnel baru.

R1(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

R3(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

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

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

R4(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

Kita lakukan Verifikasi:

R1(HUB):

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

NHS Status: E --> Expecting Replies, R --> Responding, W --> Waiting

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

Interface: Tunnel0, IPv4 NHRP Details Type:Hub, NHRP Peers:2,

# Ent Peer NBMA Addr Peer Tunnel Add State UpDn Tm Attrb

Verifikasi NHRP Nya Juga,

HUB#show ip nhrp
