說明：主要為OSPF有一點進階的LAB，整個都可以用PT完成。
練習兩個不同的Area與Redistribute，並看OSPF的Database詳細資訊。
為了減少行數，刪掉不必要的設定。
實作條件：
一、左邊跑OSPF 168 Area 1，右上跑OSPF 168 Area 0，右下跑RIP Ver2
二、左邊21.21.21.0/24，三台Router需調整成讓wg_ro_c成DR
三、右邊30.300.30.16/30，兩台Router需調整成讓wg_ro_e成DR
四、wg_ro_f將OSPF和RIP互相Redistribute
五、wg_ro_c的ip route裡要看到O E2 172.16.10.0 [110/30]
六、各Router設定Router-ID，wg_ro_a：1.1.1.1、wg_ro_b：2.2.2.2…以此類推
但我發現我把a設定2.2.2.2，b設成1.1.1.1了，請見諒 Orz
備註：
一、剛做完Lab時，在wg_ro_a show ip ospf da時，最後的Type 5有時候會只有一條192.168.65.0/24
可是有時候會有兩條 172.16.10.0/24，不知是設定有誤還是PT的BUG，詳情再問老師。
二、可以在wg_ro_c上再加上summary address，這點我沒有做，可自行練習。
