Intento configurar la configuración estática de IPv4 e IPv6 en CentOS 6.2.
La siguiente configuración funciona perfectamente:
# ifconfig eth0 x.x.x.x/29
# route add defalt gw x.x.x.y
# ip addr add dev eth0 XXXX:C810:3001:D00::3/56
# ip -6 route add default XXXX:C810:3001:D00::1
Sin embargo, quiero mantener esta configuración después de un reinicio.
Entonces hice la siguiente configuración:
Habilitar IPv6
[root@test network-scripts]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=test.net
NETWORKING_IPV6=yes
Configuración de la interfaz
[root@test network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="static"
ONBOOT="yes"
HWADDR="2C:C3:AC:A8:C3:3E"
IPADDR=x.x.x.x
GATEWAY=x.x.x.x
NETMASK=255.255.255.248
TYPE=Ethernet
IPV6INIT=yes
IPV6ADDR=XXXX:C810:3001:D00::3/56
IPV6_DEFAULTGW=XXXX:C810:3001:D00::1
DNS1=208.67.222.222
DNS2=208.67.220.220
# Only DNS{1,2} according to /usr/share/doc/initscripts-9.03.27/sysconfig.txt
# DNS3=2620:0:ccc::2
# DNS4=2620:0:ccD::2
Reiniciar la red

¡Las direcciones IPv6 de los resolvers ni siquiera están en resolv.conf!
¿Me perdí un paso de configuración?
Pensé que la configuración de IPv6 sería una formalidad.

. De lo contrario, /etc/resolv.conf se reformatea al inicio.¿No es este administrador de red en conflicto con los archivos de configuración de red estática? Deshabilite el administrador de red si ejecuta CentOS en el servidor, NM es una tontería y no hay necesidad de cambiar "dinámicamente" la configuración de la red.
