R1:
IPsec proposal R2
创建并配置IPsec提议,默认采用esp协议、MD5认证算法和隧道封装模式
Transform esp 配置隧道采用的安全协议(默认esp)
Encapsulation-mode tunnel 配置报文的封装模式
Esp authentication-algorithm sha2-256 配置ESP协议使用的认证算法(默认MD5-HMAC-96)
Esp encryption-algorithm aes-128 配置esp的加密算法(默认DES)
Display IPsec proposal 查看IPsec提议中的配置参数
Quit 安全提议配置完成
IPsec policy P1 10 manual (manual,手动协商,)
—(创建并配置IPsec策略(P1为名字,调用使用改名字,10为***,类似acl的***)
Security acl 3000 配置IPsec策略管理的acl
