Lab 10. Eigrp Default Route – Summary Address

Pada lab sebelumnya, kita sudah belajar tentang Summarization di EIGRP. Selanjutnya pada lab ini kita juga akan belajar sumarization di EIGRP, hanya saja pada lab ini kita akan menggunakan default route. Kita konfigurasikan summary address pada R3.

*R3

  •  R3(config)#int fastEthernet 1/0
  •  R3(config-if)#no ip summary-address eigrp 10 3.3.3.3 255.255.255.0
  •  R3(config-if)#ip summary-address eigrp 10 0.0.0.0 0.0.0.0

*R3

  •  R3#sh ip route

 Gateway of last resort is 0.0.0.0 to network 0.0.0.0

 D* 0.0.0.0/0 is a summary, 00:16:28, Null0

  2.0.0.0/32 is subnetted, 1 subnets

 D 2.2.2.2 [90/156160] via 23.23.23.1, 00:35:25, FastEthernet1/0

  3.0.0.0/8 is variably subnetted, 11 subnets, 5 masks

 C 3.3.3.3/32 is directly connected, Loopback0

 C 3.3.3.16/28 is directly connected, Loopback1

 C 3.3.3.32/29 is directly connected, Loopback2

 C 3.3.3.96/27 is directly connected, Loopback3

 C 3.3.3.148/30 is directly connected, Loopback4

 C 3.3.3.192/28 is directly connected, Loopback5

  12.0.0.0/24 is subnetted, 1 subnets

 D 12.12.12.0 [90/30720] via 23.23.23.1, 00:35:25, FastEthernet1/0

  23.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

 C 23.23.23.0/24 is directly connected, FastEthernet1/0

*R2

  •  R2#sh ip route

 D* 0.0.0.0/0 [90/30720] via 23.23.23.2, 00:18:56, FastEthernet1/0

  2.0.0.0/32 is subnetted, 1 subnets

 C 2.2.2.2 is directly connected, Loopback0

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

 C 12.12.12.0/24 is directly connected, FastEthernet1/0

  23.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

 C 23.23.23.0/24 is directly connected, FastEthernet1/0

*R2

  •  R2#show ip route 3.3.3.3

 % Network not in table

  •  R2#show ip route 3.3.3.17

 % Network not in table

  •  R2#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 = 20/23/32 ms

  •  R2#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 = 12/17/24 ms
