I have 4 guest VMs installed on 1 host. One of them is Vyatta (VC5). Currently we are using default Xen-bridge for communication between VMs(inter-domain or intra-domain).
I want to assign Vyatta(a guest VM) exclusively to replace Xen-bridging for VM to VM communication. Means the traffic sent from guest-1 to guest-2 bypass briging and route through vyatta(VM), instead of going to Dom0.
As William Von Hagen says in his book 'Professional Xen Virtualization'

"The choices provided with a standard Xen installation are the following:
    â    network-bridge: Bridged networking (the default)
    â    network-nat: NAT networking
    â    network-route: Routed networking
If you donât want to use one of the out-of-the-box approaches to Xen networking, the network-script parameter can also be set to the name of your own configuration script. If you need to extensively customize one of these scripts, itâs a good idea to make a copy of the default script with a different name in the /etc/xen directory, configure the Xen daemon to use your new script by changing the value of the network-script parameter to the name of your new script, and then modify the copy. This enables
you to keep a pristine copy of the original script on your system for reference purposes as well as providing a copy for your modifications."

Tell me some way where and how to chance xen 'network-script' parameters?
In fact i want to change bridge network script available in /etc/xen/scripts or write my own script in terms of vyatta. Give me some idea to which extent i have to change the scripts?
