简介

本文档介绍当DMVPN中心设置为证书颁发机构(CA)时，如何配置具有证书身份验证的动态多点VPN(DMVPN)网络。

先决条件

要求

Cisco 建议您了解以下主题：

公用密钥基础结构 (PKI)
使用预共享密钥的DMVPN
网络时间协议 (NTP)

使用的组件

本文档不限于特定的软件和硬件版本。

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

背景信息

部署基于PKI的DMVPN网络的一个相当常见的做法和推荐的方法是使用证书和显式CA服务器配置DMVPN。本文档介绍如何使用Cisco IOS® CA服务器设置PKI^基础设施：

公钥基础设施配置指南

要将此基础设施端口至DMVPN部署，请完成以下步骤：

如本例所示，让中心和分支像任何其他路由器一样向CA服务器注册和验证自身。

crypto pki trustpoint dmvpn
 enrollment url http://192.168.1.1:80
 revocation-check none
 rsakeypair dmvpn

添加此命令以更改身份验证方法身份验证策略以使用PKI而非预共享密钥。
```
crypto isakmp policy <number> 
 authentication rsa-sig
```
注意：此处不显示身份验证方法，因为PKI是默认设置。在路由器上输入show run all命令以查看配置。
```
crypto isakmp policy 2
 encr aes 192
 group 2
```

但是，当DMVPN集线器（或属于DMVPN基础设施的任何其他路由器）也需要充当CA时，会发生什么情况？为使PKI成功运行，隧道两端都需要有由同一CA签名的证书。但是，如果其中一个DMVPN路由器本身是CA，那么我们如何使该特定路由器成为PKI基础设施的活动成员？

完成以下步骤以将路由器注册到自己：

将路由器配置为CA。

crypto pki server dmvpn-ca
 issuer-name CN=rtpvpnoutbound7.cisco.com
 grant auto
 lifetime certificate 25
 lifetime ca-certificate 30
 auto-rollover
 database url nvram

在CA上使用指向CA自身的注册URL配置信任点。

crypto pki trustpoint dmvpn
 enrollment url http://192.168.1.1:80
 revocation-check none
 rsakeypair dmvpn
!
interface GigabitEthernet0/1  // <-- inerface on the same router.
 description utfwb0rder01
 ip address 192.168.1.1 255.255.255.252
 duplex full
 speed 1000
!

按照标准步骤注册CA并对其进行身份验证。

crypto pki authenticate <trustpoint>
crypto pki enroll <trustpoint>

配置属于DMVPN基础设施的其他路由器，以向CA注册和验证。
配置互联网安全关联和密钥管理协议(ISAKMP)策略，使其使用PKI进行身份验证，如前所述。

提示: Cisco建议您使用NTP，以便保持DMVPN路由器上的时钟同步。有关如何配置NTP的信息，请参阅配置NTP。

配置

注意：使用命令查找工具（仅限注册用户）可获取有关本部分所使用命令的详细信息。

故障排除

本部分提供了可用于对配置进行故障排除的信息。

思科 CLI 分析器（仅适用于注册客户）支持某些 show 命令。要查看对 show 命令输出的分析，请使用思科 CLI 分析器。

注意：使用 debug 命令之前，请参阅有关 Debug 命令的重要信息。

IPSec相关问题

这些调试应在隧道的两个受影响终端上启用。

debug dmvpn all - 此特定命令启用此组调试：

Spoke1#debug dmvpn all all
DMVPN all level debugging is on
Spoke1#show debug


NHRP:
  NHRP protocol debugging is on
  NHRP activity debugging is on
  NHRP extension processing debugging is on
  NHRP cache operations debugging is on
  NHRP routing debugging is on
  NHRP rate limiting debugging is on
  NHRP errors debugging is on
IKEV2:
  IKEV2 error debugging is on
  IKEV2 terse debugging is on
  IKEV2 event debugging is on
  IKEV2 packet debugging is on

  IKEV2 detail debugging is on



Cryptographic Subsystem:
  Crypto ISAKMP debugging is on
  Crypto ISAKMP Error debugging is on
  Crypto IPSEC debugging is on
  Crypto IPSEC Error debugging is on
  Crypto secure socket events debugging is on
Tunnel Protection Debugs:
  Generic Tunnel Protection debugging is on
DMVPN:
  DMVPN error  debugging is on
  DMVPN UP/DOWN event  debugging is on
  DMVPN detail  debugging is on
  DMVPN packet  debugging is on
  DMVPN all level debugging is on

此类详细调试并非总是必需的，不应随意启用，因为它可能会使设备过载。通常，最好从此超集创建更相关调试的子集并启用这些调试。

PKI相关问题

CA 服务器

这些命令与PKI服务器相关。如果使用Telnet或安全外壳(SSH)连接，则需要输入terminal monitor命令。

命令	描述
debug crypto pki messages	显示CA与路由器之间交互（消息转储）的详细信息
debug crypto pki server	显示加密PKI证书服务器的调试
debug crypto pki transactions	显示CA与路由器之间的交互（消息类型）

DMVPN分支

这些命令适用于头端或分支机构。要查看调试输出，如果使用Telnet/SSH连接到路由器，请输入terminal monitor命令。

命令	描述
debug crypto pki messages	显示CA与路由器之间交互（消息转储）的详细信息
debug crypto pki server	显示加密PKI证书服务器的调试
debug crypto pki transactions	显示CA与路由器之间的交互（消息类型）
debug crypto isakmp	显示有关ISAKMP和IKE事件的消息
debug crypto ipsec	显示IPSec事件
debug crypto engine	显示有关执行加密和解密的加密引擎的调试消息
