Linux – FreeBSD and Linux VLAN

freebsdipv6linuxlocal-area-networkvlan

I have a LAN and i need to create a LAB with three VLAN on my boxes, Linux and FreeBSD.

Well i create a VLAN 1 on the linux box as follow: 


sudo vconfig add eth0 1
sudo ifconfig eth0.1 inet6 add 2001:470:9b36:2::2/64

and i do the same on the FreeBSD box: 


sudo ifconfig vlan1 create
sudo ifconfig vlan1 inet6 2001:470:9b36:2::1 prefixlen 64 vlan 1 vlandev bge0

ifconfig of FreeBSD box 


vlan2: flags=8843 metric 0 mtu 1500
    options=3
    ether 00:11:85:61:90:f2
    inet6 fe80::211:85ff:fe61:90f2%vlan2 prefixlen 64 scopeid 0x5 
    inet6 2001:470:9b36:2::1 prefixlen 64 
    inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255
    nd6 options=3
    media: Ethernet autoselect (100baseTX )
    status: active
    vlan: 2 parent interface: bge0

and the ifconfig of the Linux Box: 


eth0.2    Link encap:Ethernet  HWaddr d8:d3:85:28:d3:28

          inet addr:10.0.0.2  Bcast:10.0.0.255  Mask:255.255.255.0
          inet6 addr: fe80::dad3:85ff:fe28:d328/64 Scope:Link
          inet6 addr: 2001:470:9b36:2::2/64 Scope:Global
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:962 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:43400 (42.3 KiB)

But i still not able to ping the VLANs from each side ?
What would be the states of each of the interfaces bge0 and eth0 ?

NB: the eth0 and bge0 are up and running

Have you tried something other then VLAN1? VLAN1 is typically considered to be the un-tagged VLAN. Generally you should not be trying to add that as a tagged VLAN.

I am not sure about FreeBSD, but in Linux, there is a warning when you try to use that.

How are the two systems physically connected?
