linux系统下ping ipv6

前言

ipv6正在逐渐的普及，内网设备支持ipv6协议，其相关的设备也会相应的ipv6地址

同一台交换机下互ping其ipv6地址

查看a服务器的网卡信息

[[email protected] ~]# ip a

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

b服务器ping另一台即a服务器的ipv6网卡

• 语法:
  ping6 -I 网卡 ipv6地址

• 示例:

[[email protected] ~]# ping6 -c 3 -I ens160 fe80::9480:9394:ee87:646d
PING fe80::9480:9394:ee87:646d(fe80::9480:9394:ee87:646d) from fe80::250:56ff:fe96:4171%ens160 ens160: 56 data bytes
