实例讲解DMVPN
一、ABC Technologies’ requirements to network infrastructure. (ABC科技网络公司对网络架构的需求).1.ABC Technologies decided to extend their network infrastructure, they have branches in HK, Shenzhen, Shanghai and Beijing. WEB servers in HK HQs, IP voice server in Shenzhen. They demanded each branch is able to access inside servers, Voice system will adopt IP telephony, it will be free in the intranet.
(ABC科技公司决定对网络进行扩充，在香港，深圳，上海和北京都有办事处，WEB服务器在香港总部，语音服务器在深圳。要实现各地办事处内网均能访问内部服务器，语音系统采有IP语音，内部之间通话可免费)
2.HK branch has lots of static public IP address, others will adopt ADSL PPPOE protocol, so the public IP address will be dynamic.
香港公司拥有多个固定IP，其它三地均采用ADSL的PPPOE拨号，所获IP为动态IP。
3.
According to the requirements above, to set up IPSec VPN to achieve communication in whole corporation.
根据以上要求，建设IPsec VPN去实现全网互通。
4. Configure Router in order to WEB servers can be visited by internet.
配置路由器以便WEB服务器能被互联网访问。
二、Topological Diagram 拓扑图

-----------------------------------------------------------------------
Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for
one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.
It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.
username <myuser> privilege 15 secret 0 <mypassword>
Replace <myuser> and <mypassword> with the username and password you want to
use.

YOU MUST USE CISCO CP or the CISCO IOS CLI TO CHANGE THESE
PUBLICLY-KNOWN
CREDENTIALS
Here are the Cisco IOS commands.

IF YOU DO NOT CHANGE THE PUBLICLY-KNOWN CREDENTIALS, YOU WILL NOT BE ABLE
TO LOG INTO THE DEVICE AGAIN AFTER YOU HAVE LOGGED OFF.
