Lab 8. EIGRP – Summarization

Summarization adalah suatu metode meringkas beberapa route menjadi satu route dengan menjadikan beberapa route yang berbeda network, menjadi satu network dan satu subnet tanpa menghilangkan network yang diringkas tersebut. Tujuannya, sebagai pengurang tabel routing.

Berikut kondisi awal sebelum dikonfigurasi summarization:

-R1

Router(config)#do show ip route

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 [90/409600] via 12.12.12.2, 00:17:31, Ethernet0/0

      3.0.0.0/8 is variably subnetted, 6 subnets, 5 masks

D        3.3.3.3/32 [90/435200] via 12.12.12.2, 00:17:31, Ethernet0/0

D        3.3.3.16/28 [90/435200] via 12.12.12.2, 00:05:02, Ethernet0/0

D        3.3.3.32/29 [90/435200] via 12.12.12.2, 00:04:15, Ethernet0/0

D        3.3.3.96/27 [90/435200] via 12.12.12.2, 00:03:56, Ethernet0/0

D        3.3.3.148/30 [90/435200] via 12.12.12.2, 00:03:31, Ethernet0/0

Sekarang lakukan konfigurasi summarization pada R3:

-R3

Router(config)#int e0/0

Router(config-if)#ip summary-address eigrp 10 3.3.3.0 255.255.255.0 5

 

Setelah itu kita cek Kembali table routing pada R1 dan coba ping:

 

-R1

Router(config)#do show ip route

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 [90/409600] via 12.12.12.2, 00:19:06, Ethernet0/0

      3.0.0.0/24 is subnetted, 1 subnets

D        3.3.3.0 [90/435200] via 12.12.12.2, 00:00:24, Ethernet0/0

      12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

C        12.12.12.0/24 is directly connected, Ethernet0/0

L        12.12.12.1/32 is directly connected, Ethernet0/0

      23.0.0.0/24 is subnetted, 1 subnets

-R1

Router(config)#do 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 = 1/1/2 ms

Router(config)#do ping 3.3.3.17

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 3.3.3.17, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms

Router(config)#do ping 3.3.3.33

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 3.3.3.33, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms
