需求
“A redundant campus network with three core routers in a triangle using 20G LAG links, and two distribution switches with 10G fiber uplinks to every core router.”
接著試試Add an access switch below each distribution switch.Add an Internet edge firewall to Core Router A.
這張圖裡有什麼
看懂背後的決策。
01
Connect the three core routers pairwise with LAG links to form a resilient triangle core.
02
Provide dual fiber uplinks from each core router to both distribution switches for redundant paths.
03
Use 20G LAG inter-core links and 10G fiber uplinks for scalable bandwidth.
Use this pattern when documenting or designing a redundant campus core where any core router or core link can fail without isolating the distribution layer.
