Untuk EIGRP OTP ini hanya bisa dilakukan pada versi IOS 15.x keatas yang support EIGRP Named Configuration. Untuk konfigurasi EIGRP OTP ada dua options :
• Setiap router konek satu sama lain (full-mesh).
• Satu router dijadikan pusat remote-neighbor (mirip seperti BGP Route-reflector).
Untuk lab ini kita akan menggunakan yang Opsi kedua yaitu menjadikan R1 routereflector. Coba ping dulu ke ip neighbor pastikan berhasil.
R1#ping 24.24.24.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 24.24.24.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
R1#ping 34.34.34.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 34.34.34.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms
Mulai Konfigurasi EIGRP OTP nya :
R1:
R1(config)#router eigrp IDN
R1(config-router)#address-family ipv4 unicast autonomous-system 123
R1(config-router-af)#remote-neighbors source Ethernet0/0 unicast-listen lisp-encap 123
R1(config-router-af)#af-interface Ethernet0/0
R1(config-router-af-interface)#no next-hop-self
R1(config-router-af-interface)#no split-horizon
R1(config-router-af)#network 1.1.1.1 0.0.0.0
R1(config-router-af)#network 14.14.14.0 0.0.0.255
R1(config-router-af)#exit-address-family
R2:
R2(config)#router eigrp IDN
R2(config-router)#address-family ipv4 unicast autonomous-system 123
R2(config-router-af)#neighbor 14.14.14.1 Ethernet0/0 remote 2 lisp-encap 123
R2(config-router-af)#network 2.2.2.2 0.0.0.0
R2(config-router-af)#network 24.24.24.2 0.0.0.0
R2(config-router-af)#exit-address-family
R3:
R3(config)#router eigrp IDN
R3(config-router)#address-family ipv4 unicast autonomous-system 123
R3(config-router-af)#neighbor 14.14.14.1 Ethernet0/0 remote 2 lisp-encap 123
R3(config-router-af)#network 3.3.3.3 0.0.0.0
R3(config-router-af)#network 34.34.34.3 0.0.0.0
R3(config-router-af)#exit-address-family
Pastikan interface LISP 123 sudah “up” di R2 dan R3.
R2:
R2#sh ip interface brief | i up
Ethernet0/0 24.24.24.2 YES manual up up
LISP123 2.2.2.2 YES unset up up
Loopback0 2.2.2.2 YES manual up up
R3:
R3#sh ip int brief | i up
Ethernet0/0 34.34.34.3 YES manual up up
LISP123 3.3.3.3 YES unset up up
Loopback0 3.3.3.3 YES manual up up
Cek juga apakah EIGRP Neighbornya sudah “up”.
R1:
R1#sh ip eigrp neighbors
EIGRP-IPv4 VR(IDN) Address-Family Neighbors for AS(123)
H Address Interface Hold Uptime SRTT RTO Q Seq

0 24.24.24.2 Et0/0 14 00:09:25 6 100 0 4
Cek routing table nya dan lakukan ping.
R2:
R2#sh ip route eigrp

D 3.3.3.3 [90/94501211] via 34.34.34.3, 00:08:07, LISP123
R3:
R2#sh ip route eigrp

D 3.3.3.3 [90/94501211] via 34.34.34.3, 00:08:07, LISP123
R2:
R2#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 = 1/1/2 ms
R3:
R3#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 = 4/4/5 ms
