DMVPN Lab 6 : Phase 2 Dynamic Mapping With EIGRP

By :

 LAB 6


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. 

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

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

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

Lakukan verifikasi routing eigrp nya.

HUB
HUB#show ip eigrp neighbors EIGRP 
IPv4 Neighbors for AS(12) 
HAddress Interface Hold Uptime SRTT RTO Q Seq 
                        (sec) (ms) Cnt Num 
1 192.168.10.3 Tu0 12 00:04:25 82 1434 0 3 
0 192.168.10.2 Tu0 14 00:04:47 64 1434 0 4 

HUB#show ip route eigrp 
Gateway of last resort is 12.12.12.2 to network 0.0.0.0 
 2.0.0.0/32 is subnetted, 1 subnets 
D 2.2.2.2 [90/27008000] via 192.168.10.2, 00:18:49, Tunnel0 
 3.0.0.0/32 is subnetted, 1 subnets 
D 3.3.3.3 [90/27008000] via 192.168.10.3, 00:18:31, Tunnel0

Kita cek juga routing eigrp pada setiap router Spokenya
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, 00:25:05, Tunnel0 

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, 00:25:21, Tunnel0

Dapat dilihat 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. 

HUB
HUB(config)#int tun0 
HUB(config-if)#no ip split-horizon eigrp 12

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 

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 

Lalu lakukan tes ping.

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
