inter-satellite laser links
What i said is ture now. FSO in Space
Over your head is all laster link in the Space
原來Aruba套Wifi呢 係識自己行tunnel
tunnel = encapsulation = slower
即係AP連Controller，d野全部係proprietary幫你set埋?
你一插條cat5然後就唔洗再理隻AP淨係係controller做mgnt?
公司有堆Ruckus其實可以插落隻3560度慢慢撚
其實呢個位放唔放到half depth rack呢
一個簡單既office絕對無問題啦，一隻出入router，樓下駁堆switch，做下DNS，DHCP，NAPT
揸住 CCNA 已經可以管到有分公司嘅 network
30隻routers , 因為RIPv2 30 hops
點為止一個site? 一個location 入面等於一隻router再樓下加一堆client/switch?
雖然 CCNA 淨係教咗 backbone area
OSFP 30 hops ? or unlimited ?
其實CCNA已經夠起國際 local Network
Yes, Intranet, Global one.
比如 Site A <-> HKIX <-> Site B ??
求先睇itercast講閉網 就係全程行私家線唔溝公家traffic
Local network is leased line, not HKIX
Local Network 係無 Internet
求先個大陸佬講，行私家線/closed network
Closed network no need for encryot
Site 去HKIX係BGP
Site to site 我估係行BGP private peering
Closed network is your own network, you can use for your own data transfer or you can use for Internet transfer
最基本係 Leased Line 上起MPLS Network
其實Metro線係咪姐係經ISP個infra間個vlan出黎兩頭用
明完NAT下一步最緊要係學Router dot1q
