配置了vlan感知网桥时的奇怪网桥监视事件


1

我使用以下命令在系统上配置了VLAN感知网桥:

ip link add <bridge_name> type bridge vlan_protocol 802.1Q vlan_filtering 1
ip link set dev <bridge_name> up

稍后,当添加另一个桥链接(ip link add name yoav type bridge)并使用“桥监视器”时,我们可以看到日志事件:

7a:26:53:bb:86:e5 vlan 1 master * permanent (mac address of the bridge link).

此事件的含义是什么?为什么没有接口

读取RTM_NEWNEIGH类型的netlink消息时,可以看到相同的结果-ndm_ifindex为0。

谢谢!
