[gentoo-user] 802.1q/VLAN issue

[Joe Rizzo]

I updated my gentoo system.  After emerging system and world, the system
does not work with VLANs if the interfaces are configured via the
net.eth0 script.  However if I configure the interface manually it
works.  This worked before I updated.  Any Ideas?

The conf.d/net file is below.

Thanks,
Joe Rizzo


# cat /etc/conf.d/net
config_eth0=(
    "null"
)

vlans_eth0="16"

config_eth0_16=(
    "10.8.16.16 broadcast 10.8.16.255 netmask 255.255.255.0"
)

routes_eth0_16=(
    "-net 0.0.0.0 netmask 0.0.0.0 gw 10.8.16.1"
)

After some digging around I've come up with following (working) config:

vlans_eth0="16"
vconfig_eth0=( "set_name_type VLAN_PLUS_VID_NO_PAD" )

config_vlan16=(
                 "10.8.16.16 broadcast 10.8.16.255 netmask 255.255.255.0"
)

and also there is the int vlan16 instad of eth2:16
