羽嗜茶，著經三篇，言茶之原、之法、之具尤備，天下益知飲茶矣

周末我長輩同事帶我去吃香港點心 (位於 Marriot Hotel 樓下B1 如沒記錯的話).. 是另外馬來西亞同事介紹我們這陸羽茶館地方了啦.. 下午時間還沒去機場前打算跟她吃頓午餐.. 到了過後點了許多; 香炒蘿蔔糕, 叉燒包, 古法糯米雞, 水餃, 上海煎鍋貼 等豪華食物.. 哇靠.. 這幾天真的吃到爽死啦… 還有那個海外天香港餐廳的叉燒飯, Madam Kwan 的椰漿飯, 香蕉冰淇淋等美味甜品… 哇.. 如改天有緣再拜訪啦..

OSPF Routing Lab #2

Implementing basic OSPF lab#2, configuring core OSPF config (network ospf X), static metric redistribution for ASBR: (redistribute static metric subnets metric xxx metric type 1/2), changing router IDs (router-id), clear ip ospf processes, route summarization (ABR: area xx range (IP), (summary mask), ASBR: (for BGP/EIGRP that has no area): summary-address (IP) (summary mask), understanding DR, BDR; implementing DR election (go to interface, ip ospf priority xxx), as well as to re-calculate the metric cost calculation (auto-cost reference-bandwidth xxxx)..

FC splicing, Server Rack relocation

這星期我觀察到了整個網路建設的細小過程，也可能不是每個人都有興趣去調查，但是我欲知之態讓我心感覺到不可錯失這次良機。我並抽下時間來觀察發現果然不簡單。看了工程師們同心協力爬上天花板，爬數據下面把網線拉，擺好，接下了收聽器等勞力密集的工作考驗我才能對一切感激.. 最興趣的過程當中就是光纖熔接接頭部分..

現在只要按下一個按鈕，機器就會完成一切工作.. 但是，即使是最好的熔接機製造商也不能把手工勞動從熔接中完全剔除出去。每根光纖必須在被熔接前準備好，這一過程還需要技工。首先要從光纜中取出光纖、剝離塗覆層並且清理乾淨。然後，必須切開光纖並切出一個小於1度的面，這樣兩根光纖的端面才能相互一致。 熔接機的一些功能確實使技工的工作更容易，這包括集成的照相機，它讓使用者可以看到兩根光纖的軸線，這有利於光纖對準。內建的告警系統能對不干淨的光纖或者不好的切割角度發出警告。還有，光纖識別功能可以檢測出光纖的類型，如單模、多模、非零色散位移光纖等，並根據這些參數調整熔接機。

這網頁可以去參考.. http://publish.it168.com/2005/0401/20050401502801.shtml

搬完了我全身發抖.. 數據中心裡面冷得像冰箱般的溫度… 一出來我腰酸背痛, 手無法感覺到任何東西… 就回家, 吃飯去了.. 靠…我下次肯定要請供應商來幫我們搬…

MT4 – Demo Acc

I’ve just recently found out that the existing mt4-demo2_4 decimal server listed in the Trade Servers list weren’t able to be contacted. I was searching through the internet and finally managed to retrieve the exact server name. steps:

1. go to Tools, then to Options.  (server tab)
2. delete the existing server field delete and type in mt4-demo2.ibfx.com:443
3. click the OK button.
4. register demo acc as per normal.
5. now, after filling in the necessary, the next page will appear the server list and scan button. we should be able to get numbers for that server in the ping column, click the next button.
6. the new demo account number starting with the number 5, and a password, copy to notepad and login as usual.

EIGRP Multipoint Access Lab #1

This weekend I’ve ventured the world of EIGRP by configuring load balancing between 2 routers through ‘variance’ command, as well as to understand more about how fast the network can converge through a list of successor and feasible successor…

And now, some steps to remember on configuring multipoint access on frame relay:

1. Create a multipoint sub interface in serial 0/0 (s0/0.1 multipoint), ensure s0/0’s encapsulation is frame relay before doing. After which, put an ip address, and map the destination accordingly (frame-relay map ip 172.16.124.2 102 broadcast) and frame-relay map ip 172.16.124.3 103 broadcast
2. On the spoke (R3, R4), configure frame relay on s0/0, and frame map the DLCI accordingly. (R3 frame-relay map ip 172.16.124.1 301 br), (R2 frame-relay map ip 172.16.124.1 201 br), as well as both R3 and R2 pointing to each DLCI. (R3 frame-relay map ip 172.16.124.2 301 br), R2 frame-relay map ip 172.16.124.3 201 broadcast) — this ensures that R2 / R3 knows where to send which DLCI for which route.
3. Ensure both spokes can send icmp packet to R1, R2 can send packets to R3 (vice versa) before running routing protocol.
4. After which, configure eigrp autonomous system (up2u) with NO Auto Summary!! and broadcast the network accordingly. (may want to setup a loopback at R3 & R2 for split horizon as clients for demo purposes)
5. R2 may not be able to see advertisement from R3 (vice versa) due to split horizon mechanism on which it prevents routing loops by prohibiting a router from advertising a route back onto the interface from which it was learned…
6. So.. since the adv from R2 & R3 required to be sent / received frm the same serial int, we therefore disable split horizon by going to the sub interface (s0/0.1, and type no ip split-hor eigrp (up2u)..

Configuring route summarization on each serial interfaces: go to each serial interfaces (R1) ip summary-address eigrp 25 10.1.0.0 255.255.252.0, (R2) ip summary-address eigrp 25 10.2.0.0 255.255.252.0, (R3) ip summary-address eigrp 25 10.3.0.0 255.255.252.0

Configuring bandwidth percent: ip bandwidth-percent eigrp 25 80 (increase by 30% from default bandwidth of 50%) on sub serial inteface s0/0.1 (R1)

Registration for Cisco DC v3.0

This morning I’ve managed to read the invitation email when I was half awake.. Luckily I have alrdy had a cisco ID so the registration on a cell ph wasn’t a big issue.. Well, after a few mths watching the vid tutorials, I felt that whatever I’ve absorbed requires to be hardened.. The key to an expert is repetitions imho..

No more telnetting through devices, my next step is to know more on the security setup, includes ssh keys as well as the broad domain of ipsec… Long way to go… But at least I’m starting my single step prolly this aft..
