简介

本文档介绍如何配置本机IPsec并对其进行故障排除，以保护思科身份服务引擎(ISE) 3.3 -网络接入设备(NAD)通信。可以使用交换机和ISE之间的站点到站点（LAN到LAN） IPsec互联网密钥交换版本2 (IKEv2)隧道加密RADIUS流量。本文档不涉及RADIUS配置部分。

先决条件

要求

Cisco 建议您了解以下主题：

ISE
Cisco交换机配置
一般IPsec概念
一般RADIUS概念

使用的组件

本文档中的信息基于以下软件和硬件版本：

运行软件版本17.6.5的Cisco Catalyst交换机C9200L
思科身份服务引擎版本3.3
Windows 10

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

目标是保护使用不安全的MD5散列、RADIUS和TACACS与IPsec的协议。需要考虑的事实很少：

思科ISE本地IPsec解决方案基于StrongSwan
当您在思科ISE接口上配置IPsec时，会在思科ISE和需要之间创建IPsec隧道以保护通信。NAD应在Native IPsec Settings（本地IPsec设置）下单独配置。
您可以定义预共享密钥或使用X.509证书进行IPsec身份验证。
IPsec可在GigabitEthernet1到GigabitEthernet5接口上启用。

本文档主要介绍X.509证书身份验证。“验证和故障排除”部分仅重点介绍X.509证书身份验证，预共享密钥身份验证的调试应完全相同，只是输出不同。相同的命令也可用于验证。

配置带X.509证书身份验证的IKEv2 IPsec隧道

网络图

IOS-XE交换机CLI配置

配置接口

如果尚未配置IOS-XE交换机接口，则至少应配置一个接口。例如：

interface Vlan480
 ip address 10.62.148.79 255.255.255.128
 negotiation auto
 no shutdown
! 
interface GigabitEthernet1/0/23
 switchport trunk allowed vlan 1,480
 switchport mode trunk
!

确保存在与远程对等设备的连接，应使用它来建立站点到站点VPN隧道。可以使用ping命令验证基本连通性。

配置信任点

要配置IKEv2策略，请在全局配置模式下输入crypto pki trustpoint <name>命令。例如：

注意：在IOS-XE设备上安装证书的方法有多种。在本例中，我们使用import of pkcs12 file，其中包含身份证书及其链

crypto pki trustpoint KrakowCA
 revocation-check none

导入证书

要导入IOS-XE身份证书及其链，请在特权模式下输入crypto pki import <trustpoint> pkcs12 <location> password <password>命令。例如：

KSEC-9248L-1#crypto pki import KrakowCA pkcs12 ftp://eugene:<ftp-password>@10.48.17.90/ISE/KSEC-9248L-1.pfx password <pkcs12-password>
% Importing pkcs12...Reading file from ftp://eugene@10.48.17.90/ISE/KSEC-9248L-1.pfx!
[OK - 3474/4096 bytes]

CRYPTO_PKI: Imported PKCS12 file successfully.
KSEC-9248L-1#

注意：即使证书在文档范围之外，请确保IOS-XE身份证书的SAN字段已填充其FQDN/IP地址。ISE要求对等证书具有SAN字段。

要验证证书是否已正确安装，请执行以下操作：

KSEC-9248L-1#sh crypto pki certificates KrakowCA

KSEC-9248L-1#

配置IKEv2提议

要配置IKEv2策略，请在全局配置模式下输入crypto ikev2 proposal <name>命令。例如：

crypto ikev2 proposal PROPOSAL 
 encryption aes-cbc-256
 integrity sha512
 group 16
!

配置加密IKEv2策略

要配置IKEv2策略，请在全局配置模式下输入crypto ikev2 policy <name>命令：

crypto ikev2 policy POLICY 
 proposal PROPOSAL

配置加密IKEv2配置文件

要配置IKEv2配置文件，请在全局配置模式下输入crypto ikev2 profile <name>命令。

crypto ikev2 profile PROFILE
 match address local 10.62.148.79
 match identity remote fqdn domain example.com
 authentication remote rsa-sig
 authentication local rsa-sig
 pki trustpoint KrakowCA

注意：默认情况下，ISE使用其自己的身份证书的CN字段作为IKEv2协商中的IKE身份。这就是为什么在IKEv2配置文件的“匹配身份远程”部分，您需要指定FQDN类型和域或ISE的FQDN的正确值。

为相关的VPN流量配置ACL

使用扩展或命名访问列表指定应受加密保护的流量。例如：

ip access-list extended 100
 10 permit ip host 10.62.148.79 host 10.48.23.85

注意：VPN流量的ACL在NAT后使用源和目标IP地址。

配置转换集

要定义IPsec转换集（安全协议和算法的可接受组合），请在全局配置模式下输入crypto ipsec transform-set命令。例如：

crypto ipsec transform-set SET esp-aes 256 esp-sha512-hmac 
 mode tunnel

配置加密映射并将其应用到接口

要创建或修改加密映射条目并进入加密映射配置模式，请输入crypto map全局配置命令。要完成加密映射条目，至少必须定义以下几个方面：

必须定义可向其转发受保护流量的IPsec对等体。这些是可以建立SA的对等设备。要在加密映射条目中指定IPsec对等体，请输入set peer命令。
必须定义可与受保护流量一起使用的转换集。要指定可与加密映射条目一起使用的转换集，请输入set transform-set命令。
必须定义应保护的流量。要为加密映射条目指定扩展访问列表，请输入match address命令。

例如：

crypto map MAP-IKEV2 10 ipsec-isakmp 
 set peer 10.48.23.85
 set transform-set SET 
 set pfs group16
 set ikev2-profile PROFILE
 match address 100

最后一步是将之前定义的加密映射集应用到接口。要应用此配置，请输入crypto map接口配置命令：

interface Vlan480
 crypto map MAP-IKEV2

ISE 配置

在ISE上配置IP地址

应该从CLI在接口GE1-GE5上配置地址，不支持GE0。

interface GigabitEthernet 1
  ip address 10.48.23.85 255.255.255.0
  ipv6 address autoconfig
  ipv6 enable

注意：在接口上配置了IP地址后，应用程序将重新启动：
%更改IP地址可能导致ISE服务重新启动
是否继续更改IP地址？是/否[N]：是

导入受信任的存储证书

此步骤用于确保ISE信任隧道建立时提供的对等体证书。导航到管理>系统>证书>受信任证书。单击 Import。单击Browse并选择签名的ISE/IOS-XE身份证书的CA证书。确保选中Trust for authentication within ISE 复选框。单击“Submit”。

受信任证书设置1

导入系统证书

导航到管理>系统>证书>系统证书。选择Node、Certificate File和Private key File Import。选中IPsec所对应的复选框。单击“Submit”。

受信任证书设置2

注意：只有在“本地IPsec设置”(Native IPsec Settings)下保存网络访问设备后，证书才会安装到StrongSwan上。

配置IPsec隧道

导航到管理>系统>设置>协议> IPsec >本地IPsec。单击Add。选择终止IPsec隧道的节点，配置带掩码的NAD IP地址、默认网关和IPsec接口。 选择Authentication Setting as X.509 Certificate，然后选择Certificate System Certificate Installed。

IPSEC设置1

默认网关是可选配置。事实上，您有两个选项，您可以在本地IPsec UI中配置默认网关，从而在底层操作系统中安装路由。此路由未在show running-config：

ise332/admin#show running-config | include route
ise332/admin#

ise332/admin#show ip route 

Destination Gateway Iface 
----------- ------- ----- 
10.48.23.0/24 0.0.0.0 eth1 
default 10.48.60.1 eth0 
10.48.60.0/24 0.0.0.0 eth0 
10.62.148.79 10.48.23.1 eth1
169.254.2.0/24 0.0.0.0 cni-podman1 
169.254.4.0/24 0.0.0.0 cni-podman2 
ise332/admin#

另一种方法是将Default Gateway（默认网关）留空并在ISE上手动配置路由，这样将达到相同的效果：

ise332/admin(config)#ip route 10.62.148.79 255.255.255.255 gateway 10.48.23.1
ise332/admin(config)#exit
ise332/admin#show ip route 

Destination Gateway Iface 
----------- ------- ----- 
10.48.23.0/24 0.0.0.0 eth1 
10.62.148.79 10.48.23.1 eth1 
default 10.48.60.1 eth0 
10.48.60.0/24 0.0.0.0 eth0

169.254.4.0/24 0.0.0.0 cni-podman2 
ise332/admin#

配置IPSec隧道的常规设置。配置第一阶段设置。常规设置、第一阶段设置和第二阶段设置应与IPSec隧道另一端上配置的设置匹配。

IPSEC设置2

配置Phase Two Settings，然后单击Save。

 negotiation auto

 switchport trunk allowed vlan 1,480
 switchport mode trunk
!

确保存在与远程对等设备的连接，应使用它来建立站点到站点VPN隧道。可以使用ping命令验证基本连通性。

配置IKEv2提议

要配置IKEv2策略，请在全局配置模式下输入crypto ikev2 proposal <name>命令。例如：

crypto ikev2 proposal PROPOSAL 
 encryption aes-cbc-256
 integrity sha512
 group 16
!

配置加密IKEv2策略

要配置IKEv2策略，请在全局配置模式下输入crypto ikev2 policy <name>命令：

crypto ikev2 policy POLICY 
 proposal PROPOSAL

配置加密IKEv2配置文件

要配置IKEv2配置文件，请在全局配置模式下输入crypto ikev2 profile <name>命令。

crypto ikev2 profile PROFILE
 match address local 10.62.148.79
 match identity remote address 10.48.23.85 255.255.255.255 
 authentication remote pre-share key cisco123
 authentication local pre-share key cisco123

为相关的VPN流量配置ACL

使用扩展或命名访问列表指定应受加密保护的流量。例如：

ip access-list extended 100
 10 permit ip host 10.62.148.79 host 10.48.23.85

注意：VPN流量的ACL在NAT后使用源和目标IP地址。

配置转换集

要定义IPsec转换集（安全协议和算法的可接受组合），请在全局配置模式下输入crypto ipsec transform-set命令。例如：

crypto ipsec transform-set SET esp-aes 256 esp-sha512-hmac 
 mode tunnel

配置加密映射并将其应用到接口

要创建或修改加密映射条目并进入加密映射配置模式，请输入crypto map全局配置命令。要完成加密映射条目，至少必须定义以下几个方面：

必须定义可向其转发受保护流量的IPsec对等体。这些是可以建立SA的对等设备。要在加密映射条目中指定IPsec对等体，请输入set peer命令。
必须定义可与受保护流量一起使用的转换集。要指定可与加密映射条目一起使用的转换集，请输入set transform-set命令。
必须定义应保护的流量。要为加密映射条目指定扩展访问列表，请输入match address命令。

例如：

crypto map MAP-IKEV2 10 ipsec-isakmp 
 set peer 10.48.23.85
 set transform-set SET 
 set pfs group16
 set ikev2-profile PROFILE
 match address 100

最后一步是将之前定义的加密映射集应用到接口。要应用此配置，请输入crypto map接口配置命令：

interface Vlan480
 crypto map MAP-IKEV2
