您好，请知：
以下是配置案例，请参考：
总部公网地址172.16.0.1，分支无论地址是否固定。两边私网地址用loopback地址替代。
配置步骤
地址、安全域及安全策略需自行配置放通
一、总部配置
新建ike提议
网络》VPN》ipsec》IKE提议》新建，选择相应的认证加密等参数
认证加密等参数相同的ike提议建议只配置一个，因为参数相同设备只会去匹配优先级最高的那个ike提议，优先级数值越小越优先。
新建ipsec策略
网络》VPN》ipsec》策略》新建，新建相应的ipsec策略等参数
配置ipsec策略的名称，选择接口及地址，总部设备角色选择中心节点。选择中心节点设备会下发模板方式的配置。模板方式的总部不需要配置acl，由分支配置acl来跟总部协商自动出保护的数据流。
IKE策略选择野蛮模式，IKE提议选择之前配置的ike，本端ID选择ipv4地址。
注意：本端ID一定要选择ipv4地址
Ipsec参数选择esp认证加密算法，其他保持默认。
二、分支配置
配置ike提议
网络》VPN》ipsec》IKE提议》新建，选择相应的认证加密等参数，同总部配置
配置ipsec策略和ike策略
网络》VPN》ipsec》策略》新建，新建相应的ipsec策略等参数
注意：本端ID留空，对端ID选择ipv4地址
配置ipsec保护的数据流及ipsec参数
配置关键点
总部采用模板方式无法指定分支的FQDN，总部默认下发配置
ike profile zongbu_IPv4_1
keychain zongbu_IPv4_1
exchange-mode aggressive
local-identity address 172.16.0.1
match remote identity address 0.0.0.0 0.0.0.0
match local address GigabitEthernet1/0/0
proposal 10
指定对端地址为全0，所以分支只能配置身份识别local-identity为地址，又因为大部分采用野蛮模式的分支地址是不固定的，所以分支这里本端ID只能留空，默认local-identity为地址。否则两端因为身份识别方式不一致导致协商不起来。
分支IKE策略--对端ID必须配置ipv4地址，因为分支要主动发起必须知道总部地址，另外如果分支对端ID配置成FQDN的话，下发配置如下。
ike profile fenzhi_IPv4_1
keychain fenzhi_IPv4_1
exchange-mode aggressive
local-identity fqdn fenzhi
match remote identity fqdn zongbu
match local address GigabitEthernet1/0/0
proposal 10
#
ike proposal 10
encryption-algorithm 3des-cbc
dh group2
#
ike keychain fenzhi_IPv4_1
match local address GigabitEthernet1/0/0
pre-shared-key hostname zongbu key cipher $c$3$U4JtiyOgrXVs/aYytzz3IeVQFWDORDQ7
秘钥会指定为hostname，会报找不到对应的密钥从而ike都无法建立。
命令行配置如下：
