Hi, good morning:
I am having some problems trying to set a vlan with
the Bering rc4 distribution. I going to explain what I
did it and how, to see if anyone can find the problem
or the mistake, because I think I am following the
documentation pretty good.
Here, this is a draw of what I am trying to set
---
- PC1 -
---
- eth0 IP 192.168.1.123
-
-
- eth1 IP 192.168.1.1
eth2 192.168.2.1 ---
- Bridge A - -- PC3 -
---
- eth0 IP 10.0.1.1 eth0 IP 192.168.2.3
-
-
- eth0 IP 10.0.1.2
eth2 192.168.2.2 ---
- Bridge B PC4 -
---
- eth1 IP 192.168.1.2eth0 IP 192.168.2.4
-
-
- eth0 IP 192.168.1.129
---
- PC2 -
---
BridgeA and BridgeB are running under Bering rc4 V1.2
with vlan.lrp bridge.lrp and 8021q.o and bridge.o
First I am gonna describe the situation of the
project. I have to computers, we will call them
BridgeA and BridgeB, which I wanna run as bridges.
Each computer has 3 Ethernet NICs. To apply vlan
support to the bridgeA and bridgeB I install in each
one the package vlan.lrp (wich provides the command
vconfig) and the module 8021q.o. Them to support the
bridge funcionality I install the the bridge.lrp
package and the bridge.o module.
them in each of these computers I do this:
First I assign an IP address to each NIC
BridgeA
eth0 10.0.1.1
eth1 192.168.1.1
eth2 192.168.2.1
and I set them up with the command Ifconfig
Ifconfig eth0 up
Ifconfig eth1 up
Ifconfig eth2 up
(To do this I had to install netutils.lrp because ifup
didn´t seem to work)
so I did the same in bridgeB
eth0 10.0.1.2
eth1 192.168.1.2
eth2 192.168.2.2
and I set them up with ifconfig again.
So now in each of the briges I create the Vlans
vconfig add eth0 10
vconfig add eth0 20
vconfig add eth1 10
vconfig add eth2 20
so now I have the interfaces
eth0.10 eth0.20 eth1.10 and eth2.20
so I set them up again with ifconfig like
ifconfig eth1.10 up
So now I only have to create the bridge
brctl addbr Orense
brctl addif Orense eth0.10
brctl addif Orense eth0.20
brctl addif Orense eth1.10
brctl addif Orense eth2.20
and I set the bridge up
Ifconfig Orense up
(as you can see I use the interfaces eth0 of each
bridge to connect them in a backbone between the two
machines)
so then conected to the eth1 of the bridgeA I have a
computer with a NIC that has an IP address
192.168.1.123 and conected to the eth1 of the bridgeB
I
have another NIC with 192.168.1.129.
As I see it has to work, doesn´t it? but If I do a
ping from 192.168.1.123 to 192.168.1.129 I can´t see
the other side. I only can reach the machine I am
conected to (because the IP address) but not using the
bridge and VLAN technology.
It is the same for the PC´s in the VLAN ID 20 PC3 and
PC4.
Can anyone tell me why or what I did wrong?
It works if I do the bridge with the phisical
interfaces eth0,eth1,eth2
Bridge Orense
eth0, eht1 eth2
but the porpuse of this
project is using vlan and a bridge so this:
Bridge Orense
eth0.10, eth0.20, eth1.10, eth2.20
It doesn´t work
I don´t know what is wrong here.
Thank´s for your help, I will be checking my
mail to see if anyone has the answer to this.
Bye
