Hello Bridge List:
Please help a newbie!
I have setup two freshly installed CentOS 4.3 servers and have setup
redundant BRIDGE. My plan is to have the 'redundant' BRIDGE working and then
I will add 'Shorewall' Firewall to these two servers. On both machines, I
have included the following lines in '/etc/rc.local' so that the BRIDGE will
be ACTIVE after BOOT:
/etc/rc.local
=========
# Setup BRIDGE (First Bridge)
brctl addbr tibbr1
brctl addif tibbr1 eth0
brctl addif tibbr1 eth1
ifconfig tibbr1 up
ifconfig tibbr1 12.21.237.2 netmask 255.255.255.0
brctl setageing tibbr1 300
brctl stp tibbr1 on
brctl setbridgeprio tibbr1 100
brctl setpathcost tibbr1 eth0 100
brctl setpathcost tibbr1 eth1 100
reboot
=========
Similar lines are included in the second server except the bridge name is
'tibbr2', IP addr is 12.21.237.4 & bridge & path costs are 200.
MAC addresses on each server are as follows:
Server 1:
eth0: 00:80:ad:16:f3:25
eth1: 00:30:1b:38:c6:41
Server 2:
eth0: 00:80:ad:16:e6:43
eth1: 00:30:1b:38:c4:c9
PROBLEM:
-------------
When I boot one of the servers, I get the following errors:
eth1: received packet with own address as source address
eth0: received packet with own address as source address
What are these errors & why they are appearing?
If I no-op (#) the following lines, the error disappear:
# ifconfig tibbr1 up
# ifconfig tibbr1 12.21.237.2 netmask 255.255.255.0
FYI, my current hardware setup is as follows:
T1 Line
|
Cisco 26XX Router
|
HUB -------> HUB (Current Network)
|
----------------------------
| eth0 |
fw1 fw2
| eth1 |
-----------------------------
|
HUB
|
(Future: additional Servers)
Please HELP! How can I fix the settings so the above listed PROBLEM is
resolved!!
