我已为 eth2 接口分配了一个静态 IPv6 地址，但无法 ping 通它。
以下是在/etc/sysconfig/networking/device/ifcfg-eh2
# Intel Corporation 82546EB Gigabit Ethernet Controller (Copper)
DEVICE=eth2
BOOTPROTO=none
HWADDR=00:11:0A:56:BB:68
ONBOOT=yes
HOTPLUG=no
DHCP_HOSTNAME=ipv6-http-ftp
TYPE=Ethernet
USERCTL=yes
IPV6INIT=yes
PEERDNS=no
IPV6ADDR=2001:dbc0:0a0a:0101:0000:0000:0000:0300
IPV6_DEFAULTGW=2001:dbc0:0a0a:0101:0000:0000:0000:0001
IPV6_AUTOCONF=no
ifconfig eth2 确实显示链接本地地址，但它仅显示全局地址。
ifconfig eth2
