使用 OCSP 配置 IPsec VPN 以实现证书吊销状态
此示例说明如何使用联机证书状态协议 （OCSP） 配置两个对等方，以检查 IPsec VPN 隧道第 1 阶段协商中使用的证书的吊销状态，从而提高安全性。
要求
在每台设备上：
获取并注册本地证书。这可以手动完成，也可以使用简单证书注册协议 （SCEP） 完成。
（可选）启用本地证书的自动续订。
配置安全策略以允许进出对等设备的流量。
概述
在两个对等方上，证书颁发机构 （CA） 配置文件 OCSP-ROOT 配置了以下选项：
CA 名称为 OCSP-ROOT。
注册 URL 已 http://10.1.1.1:8080/scep/OCSP-ROOT/。这是向 CA 发送 SCEP 请求的 URL。
OCSP 服务器的 URL 已 http://10.157.88.56:8210/OCSP-ROOT/。
首先使用 OCSP 检查证书吊销状态。如果 OCSP 服务器没有响应，则使用证书吊销列表 （CRL） 检查状态。CRL 网址 http://10.1.1.1:8080/crl-as-der/currentcrl-45.crlid=45。
不会检查在 OCSP 响应中收到的 CA 证书是否有证书吊销。在 OCSP 响应中收到的证书通常具有较短的生存期，并且不需要吊销检查。
