EIGRP – Default Route – Summary Address
Default route juga bisa didistribusikan melalui EIGRP sehingga masing- masing router tidak perlu membuat konfigurasi default route satu satu secara manua
R3
R3(config)#interface fastEthernet 0/0
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(config-if)#exit
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 23.23.23.2, 00:35:25, FastEthernet0/0
3.0.0.0/8 is variably subnetted, 11 subnets, 5 masks
C 3.3.3.3/32 is directly connected, Loopback0
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 23.23.23.2, 00:35:25, 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
R2
R2#sh ip route
D* 0.0.0.0/0 [90/30720] via 23.23.23.3, 00:18:56, FastEthernet0/0
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, FastEthernet0/0

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
Sebelum lanjut ke lab berikutnya hapus konfigurasi summary addressnya terlebih dahulu.
