It depends a bit on whether you want to shift all traffic, and whether the 
networks are interconnected 'higher up'.

We have a Master that is also a Media Server.  Each client has the names of 
every interface on the server in the SERVER= entries.

We created static routing for each subnet, for example:

        /usr/sbin/route add -ifp ce0 -net vlan2110      xx.xx.xx.xx
        /usr/sbin/route change -net vlan2110 -recvpipe 65535 -sendpipe 65535

That will cause the Master and the Media (same server) to make any outbound 
connections over the correct interface; the client will send data over the 
reverse path.

Any subnets that we don't have a NIC for we just let use the default interface 
(which is also the default route) on the server.  The subnets are 
interconnected, this was primarily done to prevent backup data taking up 
bandwidth on the inter-switch links.

You can in 6.x use REQUIRED_NETWORK which I assume allows you to have a 
collection of interfaces in the same subnet, but I'm not sure.

In your case I think you just need static routes, and to make sure the clients 
in network A have the name of the Interface A in their SERVER= list, etc.

Subject: [Veritas-bu] Master with multiple NIC's

Is it supported in NBU that a Solaris Master/Media has multiple NIC's for 
backups of different clients on different networks ?

Example:
Master has 2 network interfaces.  Interface A goes to network A to backup 
clients on network A;  Interface B goes to network B to backup clients on 
network B.

If it is supported how is this configured in NBU ?

The REQUIRED_INTERFACE option is to make sure that all NBU traffic goes over 
the configured network interface but you can only configure 1 interface.  Or am 
I wrong here.
