DMVPN Phase 1 with Static Mapping GNS3
DMVPN
Phase 1 with Static Mapping
Berikut ciri2 DMVPN Phase 1 :
1. Hub menggunakan mGRE tunnel
2. Spoke menggunakan GRE tunnel
3. Antar spoke dapat saling berkomunikasi melalui hub
1. Hub menggunakan mGRE tunnel
2. Spoke menggunakan GRE tunnel
3. Antar spoke dapat saling berkomunikasi melalui hub
1. Topologi LAB
2. Metode LAB
·
Gunakan topologi di atas, konfigurasikan pengalamatan ip
standard IDN
·
Konfigurasi static route di R1, R2 dan R3
·
Konfigurasi MGRE tunnel di HUB dan GRE tunnel di spoke
·
Konfigurasikan static mapping (ip nhrp map public-ip
private-ip)
Dalam LAB ini, kita
akan mengkonfigurasi :
1. HUB menggunakan MGRE tunnel
2. SPOKE menggunakan GRE tunnel
3. 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
1. HUB menggunakan MGRE tunnel
2. SPOKE menggunakan GRE tunnel
3. 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
Ø Pastikan
static routing jalan, semua router dapat melakukan ping
Ø Pastikan HUB mempunyai 2 peers, gunakan perintah show dmvpn
Ø Pastikan ip tunnel sudah benar, gunakan perintah show ip nhrp
Ø Pastikan HUB mempunyai 2 peers, gunakan perintah show dmvpn
Ø Pastikan ip tunnel sudah benar, gunakan perintah show ip nhrp

Keterangan : Saat mengkonfigurasikan mGRE tunnel, kita menggunakan perintah tunnel mode gre multipoint. Karena mapping kita akan konfigurasikan static, maka kita masukkan manual menggunakan perintah ip nhrp map public-ip private-ip.

Keterangan : Konfigurasi GRE tunnel, kita menggunakan perintahtunnel destination (ip public HUB). Di spoke, hanya perlu melakukan mapping ke Hub saja.
