Configuração estática de IPv4 e IPv6 no CentOS 6.2

Eu tento definir a configuração estática de IPv4 e IPv6 no CentOS 6.2.

A configuração abaixo funciona perfeitamente:

# 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

No entanto, quero manter essa configuração após uma reinicialização.

Então eu fiz a seguinte configuração:

Ativando o IPv6

[root@test network-scripts]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=test.net
NETWORKING_IPV6=yes

Configuração da interface

[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

A configuração do IPv6 não está funcionando ...

Os endereços IPv6 dos resolvedores não estão no resolv.conf!

Perdi uma etapa de configuração?

Eu pensei que a configuração do IPv6 seria uma formalidade ..

[root@test network-scripts]# lsb_release -a
LSB Version:    :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch

O Network Manager está tentando substituir as definições de configuração estática. Como usuário root ou sudo, execute:

service NetworkManager stop

Se você não tiver serviço, tente:

/etc/init.d/NetworkManager stop

Além disso, você pode definir as interfaces estáticas para não serem gerenciadas pelo NetworkManager, o que fiz nas minhas configurações do CentOS apenas adicionando a linha

NM_CONTROLLED=no

aos seus arquivos de configuração estáticos. Seus arquivos de configuração estática não possuem essa linha, o que significa que o NetworkManager tentará controlar essas interfaces em vez de ignorá-las.

Veja aqui para obter referência sobre como desativar e / ou desinstalar o NM.

Este gerenciador de rede não está em conflito com os arquivos de configuração de rede estática? Desative o gerenciador de rede se você executar o CentOS no servidor, o NM é tolo e não há necessidade de alterar "dinamicamente" as configurações de rede.
