買mon黎講呢 之前同A公司買 今次同B公司買
佢就會走黎問我你做乜唔同返A公司買
有陣時 Layer 3 Switch 做到既野係幾奇怪
OK 喎，不過 Xeon D 得 BGa Flavour
Supermicro 有出 Xeon D 嘅 NUC
Skylake 版 Xeon D 可以去到 18 核
剛剛 check 返 IP pool , 仲有少IP 可以用
呢件野個意思係，所有去 10.0.2.1 既packet都要經 192.168.1.1 呢個gateway (like a router)?
即係 10.0.2.1 既nexthop bind左做 192.168.1.1 ?
Static route = forcefully bind a next hop
Static route is the definitive way of routing
By manually telling where to go
因為我同時諗緊，一隻cisco router 有0/0同0/1分別係唔同subnet
suppose 0/0想出街 會static route去 0/1
Client 個 Gateway set 啱咗就自己識得 route
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.0.1 0.0.0.0 UG 100 0 0 enp0s31f6
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 virbr0
192.168.0.0 0.0.0.0 255.255.255.0 U 100 0 0 enp0s31f6
192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0
192.168.0.0既，去0.0.0.0
0.0.0.0既，去192.168.0.1
呢個case簡單D就係乜鳩都經192.168.0.1 (router
呢度如果 Gateway 係
0.0.0.0 嘅話即係無 gateway
linux check routing table 呢隻字一上google又好多野睇
route destination 0.0.0.0
default via 192.168.0.1 dev enp0s31f6 proto dhcp metric 100
169.254.0.0/16 dev virbr0 scope link metric 1000 linkdown
192.168.0.0/24 dev enp0s31f6 proto kernel scope link src 192.168.0.104 metric 100
192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 linkdown
呢個都明，my pc is a DHCP client
Bridge two interface to one interface
Or use secondary IP address
You can have many subnet in one interface
Static route can also to create load balance
不過唔知做乜野要配埋 Cisco Express Forwarding 先得
7604 with 10G engine card
我係一張 Engine + 一張 10G Line Ca4d
不過後尾就搬左第二張 engine 落第二個 chassis
雙 engine 果陣插邊個 console port 都得
Two engline card have 4 10G port with backplane
Backplane have no capacity
You don’t know each Cisco have backplane limitation ?
Not just install the card then you can use full capacity
You are not meet the full capacity 了
有啊 有次試過去到 10G line rate…… 比人打個陣
要睇返部機backplane其實去唔去到咁高capacity
但仲有8 / 16 port 10G line card
佢依家行得郁 10G routing 咁我就唔係好理佢
講到呢啲 依家比人打個陣好慘 好彩淨係試過一次咁大把 🙊
