Lab 24. EIGRP Stub summary

Assalamu'alaikum Warohmatullahi Wabarokatuh...
baik sahabat configer kali ini saya akan sedikit sharing mengenai EIGRP Stub Summary

kali ini kita akan coba EIGRP Stub Summary untuk skema jaringannya seperti ini

Sekarang kita akan konfigurasi ip dan eigrp pada semua router :

Router 1

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config)#int se1/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0
R1(config-if)#no shutdown

R1(config)#router eigrp 10
R1(config-router)#net 0.0.0.0
R1(config-router)#no auto-summary

Router 2

R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#exit
R2(config)#int se1/0
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#no sh
R2(config)#int f0/0
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#no sh
R2(config)#router eigrp 10
R2(config-router)#net 0.0.0.0
R2(config-router)#no auto-summary

Router3

R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#ex
R3(config)#int f0/0
R3(config-if)#ip add 23.23.23.1 255.255.255.0
R3(config-if)#no sh
R3(config-if)#ex
R3(config)#router eigrp 10
R3(config-router)#net 0.0.0.0
R3(config-router)#no auto-summary

setelah selesai kita cek ip route dan test ping koneksinya

R1#sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override
Gateway of last resort is not set
1.0.0.0/32 is subnetted, 1 subnets

3.0.0.0/32 is subnetted, 1 subnets
3.3.3.3 [90/2300416] via 12.12.12.2, 00:05:37, Serial1/0

23.23.23.0 [90/2172416] via 12.12.12.2, 00:05:39, Serial1/0

R1#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 = 1/2/4 ms

R1#ping 2.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/11/16 ms

R1#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 = 28/32/40 ms

buat loopback pada R2

R2(config-router)#int lo20
R2(config-if)#ip add 20.20.0.1 255.255.255.0
R2(config-if)#int lo21
R2(config-if)#ip add 20.20.1.1 255.255.255.0
R2(config-if)#int lo22
R2(config-if)#ip add 20.20.2.1 255.255.255.0
R2(config-if)#in lo23
R2(config-if)#ip add 20.20.3.1 255.255.255.0

lakukan summary pada R2 int s1/0

R2(config-if)#int s1/0
R2(config-if)#ip summary-address eigrp 10 20.20.0.0 255.255.252.0

cek table routing di R3

R3(config-router)#do sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override

Gateway of last resort is not set

1.0.0.0/32 is subnetted, 1 subnets

L 23.23.23.1/32 is directly connected, FastEthernet0/0

summary tidak pengarun di R3 karena summary di konfigurasi di int s1/0, tapi coba cek pada R1 dan lihat apakah summary berpengaruh jika berpengaruh berarti seetingan anda sudah benar dan tinggal melanjutkan

R1(config-router)#do sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override

Gateway of last resort is not set

1.0.0.0/32 is subnetted, 1 subnets
C 1.1.1.1 is directly connected, Loopback0
2.0.0.0/32 is subnetted, 1 subnets
D 2.2.2.2 [90/2297856] via 12.12.12.2, 00:26:47, Serial1/0
3.0.0.0/32 is subnetted, 1 subnets
D 3.3.3.3 [90/2300416] via 12.12.12.2, 00:07:21, Serial1/0
12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

L 12.12.12.1/32 is directly connected, Serial1/0
20.0.0.0/22 is subnetted, 1 subnets
D 20.20.0.0 [90/2297856] via 12.12.12.2, 00:03:57, Serial1/0
23.0.0.0/24 is subnetted, 1 subnets
D 23.23.23.0 [90/2172416] via 12.12.12.2, 00:26:47, Serial1/0

selanjutnya kita create lo100 pada R1

R1(config-router)#in lo100
R1(config-if)#ip add 100.100.100.100 255.255.255.255

Advertise kan kedalam RIP dan redistribusi kedalam EIGRP

R1(config-if)#router rip
R1(config-router)#ver 2
R1(config-router)#net 100.0.0.0
R1(config-router)#no au

R1(config-router)#router eigrp 10

R1(config-router)#redistribute rip metric 1 1 1 1 1

cek table routing R3

R3(config-router)#do sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override

100.0.0.0/32 is subnetted, 1 subnets

[170/2560514816] via 23.23.23.2, 00:00:28, FastEthernet0/0

Ip 100.100.100.100 terdapat pada table routing R3
tambahkan perintah ini ke ddalam R2

R2(config-if)#router eigrp 10
R2(config-router)#eigrp stub summary

Cek kembali routing table R3

R3 tidak memiliki network selain networknya sendiri, hali ini terjadi karena yang boleh di forward hanya network yang di summary saja

Cek routing table di R1

R1(config-router)#do sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route

Gateway of last resort is not set

1.0.0.0/32 is subnetted, 1 subnets

C 100.100.100.100 is directly connected, Loopback100

R1(config-router)#do ping 20.20.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 20.20.1.1, timeout is 2 seconds:
!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 20/24/36 ms

routing R1 memiliki net yang sudah di summarykan dan bila di ping berhasil
agar R3 juga memiliki routing network summary tersebut maka setting summary pada R2 di link yang menuju ke R3 dan cek table routing nya dan coba ping

R2(config-router)#int f0/0
R2(config-if)#ip sum ei 10 20.20.0.0 255.255.252.0

R3(config-router)#do sh ip route

ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override

Gateway of last resort is not set

3.0.0.0/32 is subnetted, 1 subnets
C 3.3.3.3 is directly connected, Loopback0
20.0.0.0/22 is subnetted, 1 subnets
D 20.20.0.0 [90/156160] via 23.23.23.2, 00:01:00, FastEthernet0/0
23.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C 23.23.23.0/24 is directly connected, FastEthernet0/0

L 23.23.23.1/32 is directly connected, FastEthernet0/0

R3(config-router)#do ping 20.20.2.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 20.20.2.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 8/16/40 ms
