順利通過SCSA 9
這本是我的主要教材:
Solaris 9 Sun Certified System Administrator Study Guide
出版社為Sybex ISBN:0782141811
以下是紅色部份是刊誤訂正
1.P35 TABLE 2.2
-a Checks only file attributes,do not check file contents.Checking attributes and .....
-c Checks only file contents,do not check file attributes.
我是以man pkgchk 來找出錯誤
2.P44 問題12
答案A印刷錯誤 應為uname -a
3.P109 第二行
UID 0,daemon is 1,bin is 2,nobody is 60001....
4.P118 問題15
答案應為ABCDE
我是以Table 4.6來找出答案
5.P131 中間部份 $ chmod o+w file21的下一行
will add Write permission to the other for file21.
6.P156 中間偏下的部份 約第5段
The Condition can be in one of five conditions:...
7.P163 中間部份 FORMAT MENU:少了一行
fdisk -run the fdisk program
8.P250 上面數下來第8行
to the at command is /etc/cron.d/at.deny.
Like /etc/cron.d/cron.deny,the at.deny file
9.P254 第一題題目有誤
兩個printer分別為saba及sisu
10.P319 問題10
塗黑的部份 可參考P314中間的範例
11.P406 Table 12.3
Syntax:
metahs -r pool \ old_slice new_slice
Example:

2005/05通過的，文章也是那時寫的。
接下來可能就暫停"認證考試的讀書心得"系列文章，
因為接下來就是準備年底的CCIE R/S Lab考試，等考完再寫其讀書心得吧。
2003/07的文章，之前那3個月都在讀TOEFL的書 終於在那天放棄~~~。
2004/12通過的，文章也時那時寫的，9月的CCIE R/S筆試心得就跳過了。
考場地址:
(Training Room) 26/F., Cityplaza One,
1111, King's Road, Taikoo Shing, Hong Kong.
We do everything for LOVE.
JNCIA之後，下一張就是Service Provider Routing and Switching, Specialist (JNCIS-SP)
經過一個月的準備，順利通過這一科。
Juniper考試，主要有三大方向。

因為CCSP共五科，還沒考完，所以沒Logo。
2005/03通過考試，文章也是那時寫的。

2005/03通過考試，文章也是那時寫的。
BSCI 是在2002/11通過的，文章也大概是那時寫的。
有點久遠了，但準備的方向，我想是一樣，不會有多大改變的。
頂多是教材不一樣或準備範圍不一樣罷了。
CCNP是在2002/07通過的，雖然已是舊版考試，但我想準備方式是差不多的。
CCDA是在2002/03通過的，但當時文章已不見了。
憑著先前的印象，再加上之後累積的經驗來重寫。
首次考試，因為辦理註冊手續需要時間的關係，所以建議在考試當天前一個星期，向考試中心註冊。

Final Check:
(Routing Table)
In this lab, I use Olive (JunOS 12.1R1.9) to finish the JNCIP study guide chapter 6 case study lab.
I use two VMWares to run Olive-1 and Olive-2
Olive-1 have run logical-systems r1 to r7 and Ovlie-2 have run logical-systems OSPF, P1, T1, T2, C1, and C2.
Note: Due to JNCIP study Guide use old version JunOS (5.2R2.3) and I use JunOS (12.1R1.9).
So,This lab will find some commands different.
In this lab, I use Olive (JunOS 12.1R1.9) to finish the JNCIP study guide chapter 5 case study lab.
I use two VMWares to run Olive-1 and Olive-2
Olive-1 have run logical-systems r1 to r7 and Ovlie-2 have run logical-systems RIP.
Note: Due to JNCIP study Guide use old version JunOS (5.2R2.3) and I use JunOS (12.1R1.9).
So,This lab will find some commands different.
In this lab, I use Olive (JunOS 12.1R1.9) to finish the JNCIP study guide chapter 4 case study lab.
I use two VMWares to run Olive-1 and Olive-2
Olive-1 have run logical-systems r1 to r7 and Ovlie-2 have run logical-systems T1 & OSPF.
Note: Due to JNCIP study Guide use old version JunOS (5.2R2.3) and I use JunOS (12.1R1.9).

This lab will find some commands different.
In this Lab, I use Olive to finish the JNCIP study guide chapter 2 case study Lab.
I use one Olive and runing logical-system R1-7 to simulate Router 1-7
So Router 1 is the logical-system r1.
In this Lab, I use Olive to finish the JNCIP study guide chapter 1 case study Lab.
I use one Olive and runing logical-system R1-7 to simulate Router 1-7
So Router 1 is the logical-system r1.
Primary path is optional: zero or one primary path
Secondary paths are also optional, By default a secondary path become active when a primary or other secondary, physical path fails.
Secondary paths (Standby option): Eliminates LSP signaling delay when active path fails. Additional state information must be maintained.
Administrative groups, also known as link coloring or resource classes, are manually assigned attributes that describe the color of links.
Links with the same color conceptually belong to the same class.
You can use administrative groups to implement a variety of policy-based label-switched path (LSP) setups.
MPLS Labels can be assigned manually or by signaling protocol (LDP or RSVP) in each LSR.
So, there are 3 types LSPs: Static LSPs, LDP-signaled LSPs and RSVP-signaled LSPs.
In this lab, I will use Juniper vMX to configure MPLS using RSVP-Signaled on JunOS router.
And RSVP is used for traffic engineering(TE). I will use Explicit Route Object (ERO) to do TE.
Due to the "JNCIP-SP Lab: Configuring LDP Signaling for MPLS - Part 1" is too complex, so I do another lab.
So, there are 3 types LSPs: Static LSPs, LDP-signaled LSPs and RSVP-signaled LSPs.
In this lab, I will use Juniper vMX to configure MPLS using LDP-Signaled on JunOS router.
This lab will show sham link configuration for MPLS VPN
IGP is IS-IS. R1 and R3 are PE. R2 is a BGP RR and P.
RSVP as the signaling protocol.
Two LSPs (R1_TO_R3 and R3_TO_R1) are between R1 and R3 via R2.
R1-R4, R3-R5 and R4-R5 are runing OSPF area 0.
By default, R4 lo0 will go to R5 lo0 via local link(R4 > R5).
Use sham link, R4 lo0 go to R5 lo0 via MPLS core (R4 > R1 > R2 > R3 > R5)

TrafGen(TGN) is the bulk packet generator tool of Pagent. You can setup TGN in Dynamips while you study QoS lab.

!!!I used real Cisco 3550 switch *4 and Router * 2 to do this lab. I did not use Dynamips to do this lab.!!!
Scenario:
Digital Technologies Inc (DTI) has a new city office. The design requires main trunks as
EtherChannels, with back up links, trunk ports and access ports using Catalyst 2950 and 3550
switches, and 1800 series routers. Fault tolerant links are required so all links, even those to ISP,
require backup.
Staff at the city office are in the following subnets:
1. Corporate (Manager, Accounts, Secretaries) VLAN 10
2. Sales (Marketing, Sales, Delivery) VLAN 20
3. Servers (attached to DLS 2) VLAN 30
4. Telephony VLAN 150
5. Management (For all switches) VLAN 217
