Virtual bridged networking with VLAN, could not ping
- by v.yegy
I require a virtual network with VLAN be build between two virtual hosts - which can be (lxc/ vbox -ubuntu or win xp).
I tried with lxc and vbox with Ubuntu and was finding difficult to make it work without vlan, but was successful with vbox with xp.
vbox-xp1 --- br1 ---------------- br2 ---- vbox-xp2
The config is:
brctl addbr br1; brctl addbr br2
ifconfig br1 up; ifconfig br2 up
stp br1 off; stp br2 off
ip link add name br1-br2-l0 type veth peer name br1-br2-l1
sudo brctl addif br1 br1-br2-l0
sudo brctl addif br2 br1-br2-l1
vbox - xp 1 and 2 with network ; bridged and br1 and br2 respectively.
The adapter is intel PRO/1000 MT Server and driver installed in guests.
Configured IPs and two hosts pinged!
VLAN config:
ip link add link br1 name br1-2.5 type vlan id 5
brctl addif br2 br1-2.5
create vlan 5 in xp 1 and 2 and assign ip address
Ping on with this config does not work.
Wireshark trace on interface br1-br2-l1 / br1-2.5 shows that one ping results in ~240 ping packets and each growing by 4 bytes - first one being correct and 60,
ping does not reach other host as I see mac is not learnt[arp -a].
--
if br1-2.5 is not configured, I see untagged packets in br1-br2-l1/0, but still not reaching other host as mac is not learnt.
if br1-br2-l0/1 is made down, even if br1-2.5 is up, I count not see any packets.
I tried with ebtables, but still could not make a correct config to work.

If any one here are aware of any configuration, please let me know.
I need to make a network of switches. Seems I have a very long way.
Sorry for a very long question.
Thanks and regards,
vy
