IKE安全提议
在FW1和FW2和FW3分别配置如下
ike proposal 10 注意：安全提议是有默认配置，可以修改
encryption-algorithm aes-256
dh group14
authentication-algorithm sha2-256
authentication-method pre-share
integrity-algorithm hmac-sha2-256 IKEv1中不用这个参数 IKEv2中使用这个参数
prf hmac-sha2-256
#检查：
[FW1]display ike proposal
2020-03-14 14:25:22.420
Number of IKE Proposals: 2
-------------------------------------------
IKE Proposal: 10
Authentication Method : PRE_SHARED
Authentication Algorithm : SHA2-256
Encryption Algorithm : AES-256
Diffie-Hellman Group : MODP-2048
SA Duration(Seconds) : 86400
Integrity Algorithm : HMAC-SHA2-256
Prf Algorithm : HMAC-SHA2-256
-------------------------------------------配置IKE对等体（PEER）
FW1配置 注意: 模板方式不需要配置remote-address 也可以配置网段，也可以不配置
ike peer yuanduan -----------取名
pre-shared-key Huawei@123---------------如果采用预共享方式，配置密钥
ike-proposal 10 -----------------------------调用安全提议
undo version 2-------------------------------关闭V2版本，默认就是V2版本
FW2和FW3的配置
ike peer fw1
pre-shared-key Huawei@123
ike-proposal 10
undo version 2
remote-address 202.1.1.1检查如下：
[FW1]display ike peer brief
2020-03-14 14:31:19.910
Current ike peer number: 1
---------------------------------------------------------------------------
Peer name Version Exchange-mode Proposal Id-type RemoteAddr
---------------------------------------------------------------------------
yuanduan v1 main 10 IP
第三步：IPSEC阶段二配置
配置感兴趣流（就是实际通信点）
FW1:
acl number 3000
rule 5 permit ip source 192.168.1.0 0.0.0.255 destination 192.168.2.0 0.0.0.255
rule 10 permit ip source 192.168.1.0 0.0.0.255 destination 192.168.3.0 0.0.0.255
FW2
acl number 3000
rule 5 permit ip source 192.168.2.0 0.0.0.255 destination 192.168.1.0 0.0.0.255
FW3
acl number 3000
rule 5 permit ip source 192.168.3.0 0.0.0.255 destination 192.168.1.0 0.0.0.255 注意：IKEV1感兴趣流要互为镜像，必须是相互匹配的，不是包含或者不一样的，都不能协商成功
IPSEC安全提议
在FW1和FW2和FW3配置
ipsec proposal 10
esp authentication-algorithm sha2-256
esp encryption-algorithm aes-256检查：
[FW1]display ipsec proposal
2020-03-14 14:33:58.850
Number of proposals: 1
IPSec proposal name: 10
Encapsulation mode: Tunnel
Transform : esp-new
ESP protocol : Authentication SHA2-HMAC-256
Encryption AES-256
[FW1]配置IPSEC安全策略
FW1
#
ipsec policy-template 10 10 第一个10是名称 第二个10是序号
security acl 3000-----------------------调用感兴趣流
ike-peer fw2---------------------------调用IKE PEER
proposal 10---------------------------调用IPSEC安全
#
ipsec policy ipsec_policy 10 isakmp template 10FW2和FW3的配置
ipsec policy ipsec_policy 10 isakmp 后面接isakmp的话是自动方式
security acl 3000 -----------------------调用感兴趣流
ike-peer fw1 ---------------------------调用IKE PEER
alias ipsec_policy_10
proposal 10 ---------------------------调用IPSEC安全物理接口调用
在FW1和FW2和FW3上配置
interface GigabitEthernet0/0/0
ipsec policy ipsec_policy 放行安全策略
FW1的配置
