Lab 6. Phase 2 Dynamic Mapping With EIGRP.

 

Sama seperti pada phase sebelumnya kita akan menggunakan routing IGP Over DMVPN tapi kali ini di phase 2 sebenernya konfigurasinya sama saja. Konfigurasi routing eigrp pada setiap router.

R1(HUB):

HUB(config)#router eigrp 12

HUB(config-router)#network 1.1.1.1 0.0.0.0

HUB(config-router)#network 192.168.10.1 0.0.0.0

HUB(config-router)#no auto-summary

R3(SPOKE-1):

Spoke-1(config-if)#router eigrp 12

Spoke-1(config-router)#network 2.2.2.2 0.0.0.0 

Spoke-1(config-router)#network 192.168.10.2 0.0.0.0

Spoke-1(config-router)#no auto-summary

R4(SPOKE-2):

Spoke-2(config)#router eigrp 12

Spoke-2(config-router)#network 3.3.3.3 0.0.0.0

Spoke-2(config-router)#network 192.168.10.3 0.0.0.0

Spoke-2(config-router)#no auto-summary

Dapat diliat bahwa routing table eigrp masih belum lengkap. hal ini terjadi adanya split horizon. Hal ini terjadi karena routing protocol distance vector defaultnya menerapkan split horizon dimana router tidak akan mengadvertise network di dalam interface yang sama. Maka itu kita perlu disable kan split horizon nya.

R1(HUB):

HUB(config)#int tun0

HUB(config-if)#no ip split-horizon eigrp 12

R3(SPOKE-1):

Spoke-1#sh ip route eigrp

1.0.0.0/32 is subnetted, 1 subnets

D 1.1.1.1 [90/27008000] via 192.168.10.1, 00:26:50, Tunnel0

3.0.0.0/32 is subnetted, 1 subnets

D 3.3.3.3 [90/28288000] via 192.168.10.1, 00:00:04, Tunnel0

R4(SPOKE-2):

Spoke-2#show ip route eigrp

1.0.0.0/32 is subnetted, 1 subnets

D 1.1.1.1 [90/27008000] via 192.168.10.1, 00:41:42, Tunnel0

2.0.0.0/32 is subnetted, 1 subnets

D 2.2.2.2 [90/28288000] via 192.168.10.1, 00:15:28, Tunnel0

Sekarang kita akan lakukan tes ping.

R3(SPOKE-1):

Spoke-1#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 = 40/62/76 ms

Spoke-1#ping 1.1.1.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 40/50/56 ms
