		<description><![CDATA[As with most other routing protocols, the best path to a destination is the path with the lowest metric. EIGRP has the ability to use several variables to compute the metric to a destination network. The first five listed above are those variables: bandwidth, delay, reliability, load, and MTU. Only bandwidth and delay are used [...]]]></description>

		<guid isPermaLink="false">http://blog.ghitr.com/index.php/archives/748</guid>
		<description><![CDATA[一、安装qemu manager 6.0
二、安装openvpn，低版本的openvpn在安装虚拟网卡TAP时，在vista或win7上会报驱动无法通过认证，不予以安装，此时需下载openvpn-2.1_rc15-install版本以上，即可顺利安装网卡驱动。
1、安装完成后看到网络连接内新的网卡，重命名为英文TAP0。TAP网卡负责和虚拟机通讯，虚拟机内的网卡和TAP看起来在一个交换机下。
2、将TAP0网卡设置为和本地网卡不同网段。192.168.10.31（本地网卡为192.168.0.31），掩码都是16位，网关都是192.168.0.1；（此时虚拟机如装好，可以和TAP互通，但是不通其他网络）
3、将本地连接设置为允许共享上网。此时虚拟机只要把网关设为TAP地址，即可和其他网络通讯。相当于通过虚拟机——TAP——本地连接（ICS）——外部网络。
三、qemu manager设置如下：
1、新建虚拟机，20G硬盘，linux系统。
2、网卡参数调整为557b，559e会崩溃，这是这个版本的qemu的问题；e1000没试过，据说junos8以上支持了，在vmware里可以装成功，qemu这次没试。
3、VLAN类型设置为TAP，ID填网络连接里的名称（如TAP0）
4、光盘设置为4.8-RELEASE-i386-mini.iso
5、串口设置为TCP接口，127.0.0.1，端口1007，监听不等待。
四、启动安装系统。
开机，选择第一个选项跳过——stand安装——A自动分配Q完成——stand引导——分区：按C，输入8000M，FS，挂载点/；如此完成：
ad0s1a&#160;&#160;&#160; /&#160;&#160;&#160; 8000M
ad0s1b&#160;&#160;&#160; SWAP&#160;&#160;&#160; 1000M
ad0s1e&#160;&#160;&#160; /tmp&#160;&#160;&#160; 2000M
ad0s1f&#160;&#160;&#160; /var&#160;&#160;&#160; 8800M&#160;&#160;&#160;
Q退出——mini安装——CD/DVD安装——一路回车，设置网卡，192.168.10.37，掩码16位，网关192.168.10.31（TAP地址）——一路回车，中途设置下时区和鼠标，其他全部默认。
完成后测试ping，已经可以连接任何网络。
五、安装junos
在Freebsd 上登陆FTP服务器输入用户名和密码，模式改为binary的二进制模式，要不在junos安装时出错。
切换到Lcd /var/tmp里面，使用get jinstall-9.6 上传到/var/tmp里，bye（退出）
查看junos文件ls /var/tmp
rm /dev/wd0c&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; 删除/dev/wd0c目录
ln -s /dev/ad0c /dev/wd0c&#160;&#160;&#160;&#160;&#160; mkdir /var/etc&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; 在/var下创建一个etc目录
touch /var/etc/master.passwd
touch /var/etc/inetd.conf
touch /var/etc/group
进入/var/tmp目录下
cd /var/tmp
mkdir jinst-signedcd jinst-signedtar zxfv ../jinstall-9.6R1.13-export-signed.tgz
mkdir jinstcd jinsttar zxfv ../jinstall-9.6R1.13-export.tgz
mkdir pkgtoolscd pkgtoolstar zxfv ../pkgtools.tgzcd bincp /usr/bin/true ./checkpic&#160; 把包中的pkgtools.tgz中的checkpic用/usr/bin/true替換掉cd ..
tar zcfv ../pkgtools.tgz&#160; *cd ..rm -rf pkgtoolstar zcfv /var/tmp/jinstall-9.6R1.13-export -olive.tgz&#160; [...]]]></description>

献&#160; 辞
SSLVPN 4卷实验指导一共花费了我差不多2个月的时间，真的是心血之作。在这个过程中遇到了很多困难。特别是设计“ASA策略拓扑”，足足花了一个星期来设计它，最后在回家的城铁上获得了设计灵感。
在实验指导编写过程中，给我感触最大的事情是，以前我做实验指导总会有很多学员协助我，他们和我一起进步。但是现在除了上课很少有学员能够呆在实验室看看书做做实验。大家的学习态度很有问题，不要认为到WOLF学习就只是为了证书，对知识的不懈追求和热爱才是最重要的。我不敢说自己的技术有多么牛，但是我可以说是最勤奋好学的。我有着对知识的热爱。我在献辞中说这些希望大家理解我的苦心，干我们这行一定需要持续不断的学习，否则你就会被淘汰。

SubCenter与 Center之间地址为:10.96.32.0/30相联。&#160;&#160;&#160;&#160; SubCenter为：10.96.32.2/30&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; Center为：10.96.32.1/30
