I have a 4 port card and I want to bridge br0 (tap0 & eth0), br1 (tap1 & eth1) etc. My aim is to fit several quad cards to the PC so that I can bridge many router interfaces to external switches. Am I missing something with the scripts? I have the following in 'config': HOST_IF="eth0" HOST_SETUP="dhcp" HOST_IPADDR=" HOST_GW=" DYNA_USER="user1" TAPS="tap0" HOST_IF="eth1" HOST_SETUP="dhcp" HOST_IPADDR=" HOST_GW=" DYNA_USER="user1" TAPS="tap1" . etc etc..... . TAPS="tap4" "brctl show" has br0 with eth4 & tap4 assigned. I'm running Ubuntu 10.10 Many thanks. How do you get this to work with multiple NICs?

My aim is to fit several quad cards to the PC so that I can bridge many router interfaces to external switches. Am I missing something with the scripts? I have the following in ‘config’:

HOST_IF=”eth0″
HOST_SETUP=”dhcp”
HOST_IPADDR=”
HOST_GW=”
DYNA_USER=”user1″
TAPS=”tap0″
HOST_IF=”eth1″
HOST_SETUP=”dhcp”
HOST_IPADDR=”
HOST_GW=”
DYNA_USER=”user1″
TAPS=”tap1″
.
etc etc…..
.
TAPS=”tap4″

“brctl show” has br0 with eth4 & tap4 assigned.

I’m running Ubuntu 10.10

Many thanks.

It's mean so much to my research plan. One problem is, what if I had multiple NIC and I want to connect it all to my GNS3 project? Can I just add it all at config file? Many thanks before.

Fix is to set vswitch properties (under security) to promiscuous mode. Hope this helps others with the same issue.

I must say I’m happy with the results. I have setup 4 virtual racks, Each rack consisting of 6 routers, 3 backbone routers. Fully meshed frame setup. 4 x 3700’s acting as layer3 switches using NM-16ESW.  Each rack is managed individually with the capability to start,stop the routers remotely. Add in a Terminal Server for easy access and the fact that its automatically started on boot…. :).       Hopefully tomorrow I get a chance to document it all and post it up here.  Including .net files for the racks and termserv, Config file for the TermServ and  the Linux initialization script thats a modified version of this one_here.
