◆確認
OSPFの設定終了後、まずOSPFのネイバーが確立している事を確認し、次に対抗ルーターよりOSPFルートが受信している事を確認します。
・Router1の確認
Router1#show ip ospf neighbor
Neighbor ID Pri State Dead Time Address Interface
192.168.20.2 1 FULL/BDR 00:00:38 192.168.12.2 FastEthernet0/1
Router1#show ip route ospf
O 192.168.20.0/24 [110/20] via 192.168.12.2, 00:01:57, FastEthernet0/1
・Router2の確認
Router2#show ip ospf neighbor
Neighbor ID Pri State Dead Time Address Interface
192.168.12.1 1 FULL/DR 00:00:33 192.168.12.1 FastEthernet0/0
Router2#show ip route ospf
O 192.168.10.0/24 [110/20] via 192.168.12.1, 00:04:55, FastEthernet0/0
◆VPCSの設定
引き続き、Router1及び2にそれぞれ接続するPC1、PC2の設定を行います。
ここでは仮想マシン等の代わりにVPCSを使用します。
・PC1の設定
PC1> ip 192.168.10.10/24 192.168.10.1
Checking for duplicate address...
PC1 : 192.168.10.10 255.255.255.0 gateway 192.168.10.1
PC1> show ip
NAME : PC1[1]
IP/MASK : 192.168.10.10/24
GATEWAY : 192.168.10.1

・PC2の設定
PC2> ip 192.168.20.20/24 192.168.20.2
Checking for duplicate address...
PC1 : 192.168.20.20 255.255.255.0 gateway 192.168.20.2
PC2> show ip

◆ルーター越しのPCへ接続確認。
上記確認後、ルーター越しのPC1とPC2間で接続できるのか確認します。
・PC1からPC2への接続確認
PC1> ping 192.168.20.20 -c 4
192.168.20.20 icmp_seq=1 timeout ←設定直後は最初の2回ぐらいはタイムアウトするっぽい
192.168.20.20 icmp_seq=2 timeout
84 bytes from 192.168.20.20 icmp_seq=3 ttl=62 time=62.930 ms
84 bytes from 192.168.20.20 icmp_seq=4 ttl=62 time=62.925 ms
PC1> ping 192.168.20.20 -c 4 ←念の為にもう一度行い、正常に接続されることを確認。
