1.Linux Macvlan 2.图解几个与Linux网络虚拟化相关的虚拟网卡-VETH/MACVLAN/MACVTAP/IPVLAN 3.创建macvlan的命令
环境
Centos7.9

[rootcentos7-10 ~]# TYPE 说明 macvlan 网络包括private 、vepa 、bridge 、passthru 、source概念参见 Linux Macvlan 和 图解几个与Linux网络虚拟化相关的虚拟网卡-VETH/MACVLAN/MACVTAP/IPVLAN
[rootcentos7-10 ~]# ip link help macvlan // TYPE类型是macvlan
Usage: ... macvlan mode MODE [flag MODE_FLAG] MODE_OPTSMODE: private | vepa | bridge | passthru | source
MODE_FLAG: null | nopromisc
MODE_OPTS: for mode source:macaddr { { add | del } macaddr | set [ macaddr [ macaddr ... ] ] | flush }
[rootcentos7-10 ~]# 1.2 创建Macvlan
基于enp0s5创建两块macvlan网卡分别是enp0s5.100
// 创建两个macvlan模式bridge
