Los grupos IPM<\/strong>P<\/strong>, sirven para a\u00f1adir tolerancia de fallos de tarjetas de Red(NICs)<\/strong>, es decir, que si una de las tarjetas de Red falla,\u00a0la otra sigue dando servicio. Siempre mejor todo redundado.<\/p>\n

Estos son los pasos para configurar un grupo IPMP en una m\u00e1quina Solaris:<\/p>\n

Comprobar la configuraci\u00f3n de red actual en la m\u00e1quina, en este caso vemos que solo hay configurada la interfaz vnet0:<\/p>\n

[root@solaris1]: \/root # ifconfig -a\n\nlo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0inet 127.0.0.1 netmask ff000000\n\nvnet0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0inet 192.168.1.56 netmask ffffff00 broadcast 192.168.1.255\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0ether 0:14:4f:fb:c9:5f<\/pre>\n
<\/p>\n
Eliminar interfaz vnet0 para dejar la configuraci\u00f3n de red limpia:<\/p>\n
\u00a0[root@solaris1]: \/root # ifconfig vnet0 unplumb<\/pre>\n
Vemos que vnet0 se ha eliminado correctamente:<\/span><\/p>\n
[root@solaris1]: \/root # ifconfig -a\n\nlo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1\n\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0inet 127.0.0.1 netmask ff000000<\/pre>\n
Comprobar que tenemos dos dispositivos de Red preparados:<\/p>\n
[root@solaris1]: \/root # grep -i network \/etc\/path_to_inst\n\n\"\/virtual-devices@100\/channel-devices@200\/network@0\" 0 \"vnet\"\n\n\"\/virtual-devices@100\/channel-devices@200\/network@1\" 1 \"vnet\"<\/pre>\n
A\u00f1adir al fichero \/etc\/netmasks la red y m\u00e1scara a la que pertenece la IP que vamos a asignar a la m\u00e1quina:<\/p>\n
[root@solaris1]: \/root # vi \/etc\/netmasks\n\n192.168.236.0 255.255.255.0<\/pre>\n
A\u00f1adir al \/etc\/hosts la IP que vamos a asignar a la m\u00e1quina y el nombre con el que va a resolverla:<\/span><\/p>\n
\u00a0[root@solaris1]: \/root # vi \/etc\/hosts\n\n192.168.236.16 \u00a0\u00a0\u00a0solaris1 solaris1.mi.domain loghost<\/pre>\n
Crear los ficheros de configuraci\u00f3n del grupo IPMP, en este caso para la VLAN 236:<\/span><\/p>\n
\u00a0[root@solaris1]: \/root # vi \/etc\/hostname.vnet236000\n\nsolaris1 group IPMP236 up<\/pre>\n
 <\/p>\n
[root@solaris1]: \/root # vi \/etc\/hostname.vnet236001\n\ngroup IPMP236 standby up<\/pre>\n
Configurar la ruta por defecto o default gateway:<\/span><\/p>\n
[root@solaris1]: \/root # vi \/etc\/defaultrouter\n\n192.168.236.1<\/pre>\n
Reiniciamos la m\u00e1quina:<\/p>\n
[root@solaris1]: \/root # sync\n[root@solaris1]: \/root # sync\n[root@solaris1]: \/root # sync\n[root@solaris1]: \/root # init 6\n<\/span><\/pre>\n
Comprobamos que la configuraci\u00f3n de red es correcta:<\/p>\n
