15.3.1 全互联结构DVPN综合配置示例
本示例拓扑结构如图15-6所示。整个DVPN网络呈Full-Mesh（全互联）结构，各设备接口的IP地址分配如表15-15所示。示例中，主/备VAM 服务器负责管理、维护各个节点的信息；AAA服务器负责对VAM客户端进行认证和计费管理；两个Hub互为备份，负责数据的转发和路由信息的交换。Spoke与Hub之间建立永久隧道连接，其中Spoke 1只通过一个隧道接口Tunnel1与其他VAM客户端建立DVPN连接，Spoke 3只通过一个隧道接口Tunnel2与其他VAM客户端建立DVPN连接，Spoke 2通过两个隧道接口Tunnel1、Tunnel2与其他VAM客户端建立DVPN连接。且同一VPN域中，任意的两个Spoke之间在有数据传输时可直接动态建立隧道连接。

根据15.2介绍的DVPN基本配置思路可以很容易地得出Hub路由器、各Spoke路由器，以及各VAM服务器的以下具体配置步骤。
一、主VAM服务器的配置
（1）按照图中标注配置主VAM服务器IP地址（略）
（2）配置AAA认证（方案为RADIUS）。
<MainServer> system-view
[MainServer] radius scheme rad1 !---创建一个名为rad1的RADIUS认证方案
[MainServer-radius-radsun] primary authentication 192.168.1.11 1812 !--- 配置主RADIUS认证/授权服务器的IP地址为192.168.1.11，UDP端口采用默认的1812号端口
[MainServer-radius-radsun] primary accounting 192.168.1.11 1813 !--- 配置主RADIUS计费服务器的IP地址为192.168.1.11，UDP端口采用默认的1813号端口
[MainServer-radius-radsun] key authentication lycb !--- 配置RADIUS认证/授权报文的共享密钥为lycb
[MainServer-radius-radsun] key accounting lycb !--- 配置RADIUS计费报文的共享密钥为lycb
[MainServer-radius-radsun] server-type standard !--- 指定采用标准类型的RADIUS服务器，还可以选择“extended”选项，指定RADIUS服务器支持私有RADIUS标准
[MainServer-radius-radsun] user-name-format with-domain !--- 设置发送给RADIUS服务器的用户名采用带ISP域名的格式：userid@isp-name，还可以选择“without-domain”选项，则用户名格式不带ISP域名。如果采用不带域名格式，则不同域中的用户名不要一样
[MainServer-radius-radsun] quit
（3）配置ISP域的AAA方案。
[MainServer] domain domain1 !---创建一个名为domain1的ISP域
[MainServer-isp-domain1] authentication default radius-scheme rad1 !---指定domain1中所有用户默认采用名为前面创建的名为rad1的RADIUS认证/授权方案
[MainServer-isp-domain1] accounting default radius-scheme rad1 !---指定domain1中所有用户默认采用名为前面创建的名为rad1的RADIUS计费方案
[MainServer-isp-domain1] quit
[MainServer] domain default enable domain1 !--- 配置系统默认的ISP域为domain1，所有在登录时没有提供ISP域名的用户都属于这个域
（4）配置主VAM服务器，指定不同VPN域中的预共享密钥、认证模式和所对应的Hub地址，然后启用VAM服务器功能。
[MainServer] vam server ip-address 192.168.1.22 !----指定VAM Server上的监听IP地址，采用默认的UDP 18000号端口
[MainServer] vam server vpn 1 !----创建VPN域1。注意，这里的VPN域与ISP域不一样，一个ISP域下可以有多个VPN域
[MainServer-vam-server-vpn-1] pre-shared-key simple 123456 !---配置预共享密钥为123456
[MainServer-vam-server-vpn-1] authentication-method chap !----配置对客户端进行CHAP认证
!---下面三条用来指定VAM服务器所服务的，在VPN域1中的两个Hub的私网地址，对应Hub1和Hub2上的Tunnel1接口IP地址。
[MainServer-vam-server-vpn-1] hub private-ip 10.0.1.1
[MainServer-vam-server-vpn-1] hub private-ip 10.0.1.2
[MainServer-vam-server-vpn-1] quit
[MainServer] vam server vpn 2 !---创建VPN域2
[MainServer-vam-server-vpn-2] pre-shared-key simple 654321 !----配置预共享密钥为654321
[MainServer-vam-server-vpn-2] authentication-method pap !---配置对客户端进行PAP认证
!--- 面三条用来指定VAM服务器所服务的，在VPN域2中的两个Hub的私网地址，对应Hub1和Hub2上的Tunnel2接口IP地址。
[MainServer-vam-server-vpn-2] hub private-ip 10.0.2.1
[MainServer-vam-server-vpn-2] hub private-ip 10.0.2.2
[MainServer-vam-server-vpn-1] quit
[MainServer] vam server enable all !----启动所有VPN域的VAM 服务器功能
二、备份VAM服务器的配置
下面再来配置备份VAM服务器。这部分除备份VAM服务器的监听IP地址配置外，其他的配置与主VAM服务器的都一样，因为它们本来就是用来进行相互备份的，具体配置参见前面介绍的主VAM服务器配置。
三、Hub1的配置
（1）配置各接口的IP地址（略）。
（2）配置VAM客户端，为不同VPN域创建不同的VAM客户端，并指定主/备VAM服务器地址，进行身份认证的本地用户名和预共享密钥，最后启用VAM客户端服务。
<Hub1> system-view
!---下面两条是创建VPN域1的客户端dvpn1hub1。
[Hub1] vam client name dvpn1hub1
[Hub1-vam-client-name-dvpn1hub1] vpn 1
!---下面三条是配置VAM服务器的IP地址及VAM客户端的预共享密钥。
[Hub1-vam-client-name-dvpn1hub1] server primary ip-address 192.168.1.22
[Hub1-vam-client-name-dvpn1hub1] server secondary ip-address 192.168.1.33
[Hub1-vam-client-name-dvpn1hub1] pre-shared-key simple 123456
!---下面三条是配置Hub1上VPN1域中的本地用户，用户名为dvpn1hub1，密码为dvpn1hub1。
[Hub1-vam-client-name-dvpn1hub1] user dvpn1hub1 password simple dvpn1hub1
[Hub1-vam-client-name-dvpn1hub1] client enable
[Hub1-vam-client-name-dvpn1hub1] quit
!---下面两条创建VPN域2的客户端dvpn2hub1。
[Hub1] vam client name dvpn2hub1
[Hub1-vam-client-name-dvpn2hub1] vpn 2
!---下面三条是配置VAM Server的IP地址及VAM Client的预共享密钥。
[Hub1-vam-client-name-dvpn2hub1] server primary ip-address 192.168.1.22
[Hub1-vam-client-name-dvpn2hub1] server secondary ip-address 192.168.1.33
[Hub1-vam-client-name-dvpn2hub1] pre-shared-key simple 654321
!---下面三条是配置Hub1上VPN2域中的本地用户，用户名为dvpn2hub1，密码为dvpn2hub1。
[Hub1-vam-client-name-dvpn2hub1] user dvpn2hub1 password simple dvpn2hub1
[Hub1-vam-client-name-dvpn2hub1] client enable
[Hub1-vam-client-name-dvpn2hub1] quit
（3）配置IPsec安全框架，创建安全提议，对等体、IPSec安全框架。
!---下面几条是配置IPsec安全提议。
[Hub1] ipsec proposal propo1
[Hub1-ipsec-proposal-vam] encapsulation-mode tunnel
[Hub1-ipsec-proposal-vam] transform esp
[Hub1-ipsec-proposal-vam] esp encryption-algorithm des
[Hub1-ipsec-proposal-vam] esp authentication-algorithm sha1
[Hub1-ipsec-proposal-vam] quit
!---下面几条是配置IKE对等体。
[Hub1] ike peer peer1
[Hub1-ike-peer-vam] pre-shared-key abcdef
[Hub1-ike-peer-vam] quit
!---下面几条是配置IPsec安全框架。
[Hub1] ipsec profile profile1
[Hub1-ipsec-profile-vamp] proposal propo1
[Hub1-ipsec-profile-vamp] ike-peer peer1
[Hub1-ipsec-profile-vamp] sa duration time-based 600
[Hub1-ipsec-profile-vamp] pfs dh-group2
[Hub1-ipsec-profile-vamp] quit
【经验之谈】IPSec安全框架中所配置的安全提议名、对等体名和安全框架名可以在全网中采用相同的名称，当然也可以采用不同的名称，因为它们都是本地配置，仅对本地有意义。通常为了怕搞混，整个网络都采用相同的安全提议名、相同的的对等体名，相同的安全框架名。
（4）配置DVPN隧道，指定不同VPN域中的隧道接口IP地址（这要与前面在VAM服务器配置的Hub地址一致）、OSPF网络类型和引用的安全框架名称。
!---下面几条是配置VPN域1的隧道接口Tunnel1。
[Hub1] interface tunnel 1
[Hub1-Tunnel1] tunnel-protocol dvpn udp
[Hub1-Tunnel1] vam client dvpn1hub1
[Hub1-Tunnel1] ip address 10.0.1.1 255.255.255.0
[Hub1-Tunnel1] source ethernet 1/1
[Hub1-Tunnel1] ospf network-type broadcast
[Hub1-Tunnel1] ipsec profile profile1
[Hub1-Tunnel1] quit
!---下面几条是配置VPN域2的隧道接口Tunnel2。
[Hub1] interface tunnel 2
[Hub1-Tunnel2] tunnel-protocol dvpn udp
[Hub1-Tunnel2] vam client dvpn2hub1
[Hub1-Tunnel2] ip address 10.0.2.1 255.255.255.0
[Hub1-Tunnel2] source ethernet 1/1
[Hub1-Tunnel2] ospf network-type broadcast
[Hub1-Tunnel2] ipsec profile profile1
[Hub1-Tunnel2] quit
（5）配置OSPF路由，宣告所连接的私网与公网。所连接的私网就是其Tunnel接口所连接的网络。但这里宣告的都是对应接口的IP地址，指定在对应接口上启用OSPF路由协议。Tunnel接口上所配置的IP地址都私网的。
!---下面几条是配置公网的路由信息。
[Hub1] ospf 100
[Hub1-ospf-100] area 0
[Hub1-ospf-100-area-0.0.0.0] network 192.168.1.1 0.0.0.255
[Hub1-ospf-100-area-0.0.0.0] quit
!---下面几条是配置私网的路由信息。
[Hub1] ospf 200
[Hub1-ospf-200] area 0
[Hub1-ospf-200-area-0.0.0.0] network 10.0.1.1 0.0.0.255
[Hub1-ospf-200-area-0.0.0.0] quit
[Hub1] ospf 300
[Hub1-ospf-300] area 0
[Hub1-ospf-300-area-0.0.0.0] network 10.0.2.1 0.0.0.255
【经验之谈】公网与私网的OSPF路由进程要不一样，物理连接的私网和通过Tunnel接口连接的虚拟私网也要用不同的OSPF路由进程。但都可以仅在骨干区域area 0中配置。

（1）配置各接口的IP地址（略）。
（2）配置VAM客户端。
<Hub2> system-view

[Spoke2-ospf-300-area-0.0.0.0] network 10.0.4.1 0.0.0.255
七、Spoke3的配置
（1）配置各接口的IP地址（略）。
（2）配置VAM客户端。因为Sopke 3只有Tunnel 2一个虚拟隧道接口，所以只需配置VPN 2域，无需配置VPN 1中的VAM客户端。
<Spoke3> system-view
!---下面两条是创建VPN域2的客户端dvpn2spoke2。
[Spoke3] vam client name dvpn2spoke3
[Spoke3-vam-client-name-dvpn2spoke3] vpn 2
!---下面三条是配置VAM Server的IP地址及VAM Client的预共享密钥。
[Spoke3-vam-client-name-dvpn2spoke3] server primary ip-address 192.168.1.22
[Spoke3-vam-client-name-dvpn2spoke3] server secondary ip-address 192.168.1.33
[Spoke3-vam-client-name-dvpn2spoke3] pre-shared-key simple 654321
!---下面三条是配置本地用户，用户名为dvpn2spoke3，密码为dvpn2spoke3。
[Spoke3-vam-client-name-dvpn2spoke3] user dvpn2spoke3 password simple dvpn2spoke3
[Spoke3-vam-client-name-dvpn2spoke3] client enable
[Spoke3-vam-client-name-dvpn2spoke3] quit
（3）配置IPsec安全框架。在名称上可以不一样，但配置上要与Hub上的配置一致。
!---下面几条是配置IPsec安全提议。
[Spoke3] ipsec proposal propo3
[Spoke3-ipsec-proposal-vam] encapsulation-mode tunnel
[Spoke3-ipsec-proposal-vam] transform esp
[Spoke3-ipsec-proposal-vam] esp encryption-algorithm des
[Spoke3-ipsec-proposal-vam] esp authentication-algorithm sha1
[Spoke3-ipsec-proposal-vam] quit
!---下面三条是配置IKE对等体。
[Spoke3] ike peer peer3
[Spoke3-ike-peer-vam] pre-shared-key abcdef
[Spoke3-ike-peer-vam] quit
!---下面几条是配置IPsec安全框架。
[Spoke3] ipsec profile profile3
[Spoke3-ipsec-profile-vamp] proposal propo3
[Spoke3-ipsec-profile-vamp] sa duration time-based 600
[Spoke3-ipsec-profile-vamp] pfs dh-group2
[Spoke3-ipsec-profile-vamp] quit
（4）配置DVPN隧道。
!—下面几条是配置VPN域2的隧道接口Tunnel2及属性
[Spoke3] interface tunnel 2
[Spoke3-Tunnel2] tunnel-protocol dvpn udp
[Spoke3-Tunnel2] vam client dvpn2spoke3
[Spoke3-Tunnel2] ip address 10.0.2.3 255.255.255.0
[Spoke3-Tunnel2] source ethernet 1/1
[Spoke3-Tunnel2] ospf network-type broadcast
[Spoke3-Tunnel2] ospf dr-priority 0
[Spoke3-Tunnel2] ipsec profile profile3
[Spoke3-Tunnel2] quit
（5）配置OSPF路由。
!---下面几条是配置公网的路由信息。
[Spoke3] ospf 100
[Spoke3-ospf-100] area 0
[Spoke3-ospf-100-area-0.0.0.0] network 192.168.1.5 0.0.0.255
[Spoke3-ospf-100-area-0.0.0.0] quit
!---下面几条是配置私网的路由信息。
[Spoke3] ospf 200
[Spoke3-ospf-200] area 0
[Spoke3-ospf-200-area-0.0.0.0] network 10.0.2.3 0.0.0.255
[Spoke3-ospf-200-area-0.0.0.0] network 10.0.5.1 0.0.0.255
八、验证配置结果。
首先可使用“display vam server address-map all”命令查看注册到主VAM服务器的所有VAM客户端的地址映射信息。结果显示Hub1、Hub2、Spoke1、Spoke2和Spoke3均已将地址映射信息注册到VAM服务器。
[MainServer] display vam server address-map all
VPN name: 1
Total address-map number: 4
Private-ip Public-ip Type Holding time
10.0.1.1 192.168.1.1 Hub 0H 52M 7S

10.0.2.3 192.168.1.5 Spoke 0H 11M 25S
10.0.2.4 192.168.1.4 Spoke 0H 18M 32S
用同样方法可以查看注册到备份VAM服务器的所有VAM客户端的地址映射信息。
再使用display dvpn session all命令查看Hub1上的DVPN隧道信息。输出信息显示VPN 1中Hub1与Hub2、Spoke1、Spoke2建立了永久隧道；VPN 2中Hub1与Hub2、Spoke2、Spoke3建立了永久隧道。Hub2上的显示信息与Hub1类似。
