Lab 11 EIGRP - Filtering AD

Assalamu'alaikum Warohmatullahi Wabarokatuh...
baik sahabat configer kali ini saya akan sedikit sharing mengenai Filtering AD
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 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.1 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 12.12.12.2 0.0.0.0
R2(config-router)#net 2.2.2.2 0.0.0.0
R2(config-router)#net 23.23.23.2 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 3.3.3.3 0.0.0.0
R3(config-router)#net 23.23.23.1 0.0.0.0
R3(config-router)#no auto-summary

Kondisi awal sebelum kita konfigurasi filtering AD

R3(config)#do sh ip route
Codes: 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

Gateway of last resort is not set

     1.0.0.0/32 is subnetted, 1 subnets
D       1.1.1.1 [90/2323456] via 23.23.23.2, 00:19:58, FastEthernet0/0
     2.0.0.0/32 is subnetted, 1 subnets
D       2.2.2.2 [90/409600] via 23.23.23.2, 00:18:33, FastEthernet0/0
     3.0.0.0/32 is subnetted, 1 subnets
C       3.3.3.3 is directly connected, Loopback0
     23.0.0.0/24 is subnetted, 1 subnets
C       23.23.23.0 is directly connected, FastEthernet0/0
     12.0.0.0/24 is subnetted, 1 subnets
D       12.12.12.0 [90/2195456] via 23.23.23.2, 00:19:58, FastEthernet0/0

Konfigurasikan AD yang paling besar yakni 255

R3(config)#access-list 10 permit 1.1.1.1 
R3(config)#router eigrp 10
R3(config-router)#distance 255 0.0.0.0 255.255.255.255 10

setelah itu kita cek lagi table routingnya

R3(config-router)#do sh ip route 
Codes: 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

Gateway of last resort is not set

     2.0.0.0/32 is subnetted, 1 subnets
D       2.2.2.2 [90/409600] via 23.23.23.2, 00:01:41, FastEthernet0/0
     3.0.0.0/32 is subnetted, 1 subnets
C       3.3.3.3 is directly connected, Loopback0
     23.0.0.0/24 is subnetted, 1 subnets
C       23.23.23.0 is directly connected, FastEthernet0/0
     12.0.0.0/24 is subnetted, 1 subnets
D       12.12.12.0 [90/2195456] via 23.23.23.2, 00:01:41, FastEthernet0/0

oke sahabat konfiger ip loopback 1.1.1.1 sudah tidak terdapat lagi dalam tabel routing di R3 dan apabila di ping pun tidak akan terhubung

R3(config-router)#do 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 0 percent (0/5)
