My goal is to create a bridge to do traffic shaping for a subnet.
I am trying to create a bridge following the Linux Foundation sample
setup in a VMware CentOS guest OS (before the router) using the
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1
ifconfig eth0 down
ifconfig eth1 down
ifconfig eth0 0.0.0.0 up
ifconfig eth1 0.0.0.0 up
ifconfig eth1 192.168.1.167
The problem: A flood of ARP requests from the Vyatta machine
(10.244.2.19) looking for the DNS Server (10.244.2.1) on the upper
network shuts down the entire network.

Do virtual terminals still work (Alt+F2, Alt+F3, ...)? If yes, then
you're not receiving a dhcp response and your dhclient is configured
with a long timeout.
If no, then one of your kernel modules is hanging your system.
Include the output of "uname -a" and "lsmod".
