>Description:
"Since FreeBSD 5.3 a vlan device can be created and configured with one command:
ifconfig vlan_device.vlan_id create"
Quote from here - http://people.freebsd.org/~arved/vlan/vlan_en.html
This is so, but have some problems with ifconfig and rc scripts.
1. ifconfig does not load if_vlan.ko automatically, when using this syntax. Need to add if_vlan_load="YES" into loader.conf
2. /etc/rc.d/netif has a similar with this syntax problem also.
And may be similar errors in other places.
In rc.conf something like this:
cloned_interfaces="xl0.101 xl0.102"
ifconfig_xl0_101="inet 10.10.10.1/30"
ifconfig_xl0_102="inet 10.10.10.5/30"
