红帽全球峰会25.8. 配置 NetworkManager 以避免使用特定配置集提供默认网关
您可以配置 NetworkManager 从不使用特定的配置文件来提供默认网关。对于没有连接到默认网关的连接配置集，请按照以下步骤操作。
先决条件
- 没有连接到默认网关的连接的 NetworkManager 连接配置文件存在。
流程
如果连接使用动态 IP 配置，配置 NetworkManager 不使用这个连接作为相应 IP 类型的默认连接，意味着 NetworkManager 永远不会为其分配默认路由：
# nmcli connection modify <connection_name> ipv4.never-default yes ipv6.never-default yes请注意，将
ipv4.never-default和ipv6.never-default设为yes，会自动从连接配置文件中删除相应协议默认网关的 IP 地址。激活连接：
# nmcli connection up <connection_name>
验证
-
使用
ip -4路由和ip -6 route命令，来验证 RHEL 是否未对 IPv4 和 IPv6 协议的默认路使用网络接口。
