在企業中常會遇到一些特殊的架構或需求，所以在這個LAB加入了我在工作上遇到的一些問題，順便一起放進這個LAB中，有興趣的人可以參考看看!!!
Basic Config :
LAB Topology :
LAB Topic :
1. R1 static route 172.31.2.0/24 to R2 for Loopback IP 。
2. R2 default route 0.0.0.0/0 to R1 。
3. R3 有一筆host route to R1 (ip route 172.31.2.1 255.255.255.255 10.3.1.1)
4. 將RIPv2 redistribute進EIGRP 1。
5. 將EIGRP 2 redistribute進EIGRP 1。
6. 將R6 Loopback IP 做summary到R5。
7. All Loopback IP 需都可互ping通。
8. 在R3上將static route redistribute 進EIGRP中。
9. R1~R4要往R5、R6時，先走R3上的Serial0/0。
10. R5、R6要往R1~R4時，先走Serial0/0。
11. R6 to R2建立Tunnel，(網段為172.32.1.0/30)。
