Dynamic routing is the most appropriate and efficient solution. You
simply advertise your network address to receive traffic.
If you don't wish to receive traffic you remove the advertisement.
Because of this it is easier and cleaner to configure and maintain your
routes. Dynamic routing is PULL routing whilst static routing is PUSH
routing and therefore in dynamic routing the receiver has better control for

When I bring the 192.168.2.0/24 network up I want to be able to
broadcast that 192.168.1.0/24 network so that the 126.96.36.199/24
network and anything coming in via 188.8.131.52 knows that it is
accessible via the 192.168.1.2 interface, but when I don't have the
192.168.2.0/24 network up I don't want to broadcast it, or let the
192.168.1.0/24 or the public world know anything about it.
I have installed quagga where shown but I don't know whether I should
be using RIP or BGP and I don't know wheta the config files should
You can do RIP, OSPF, or BGP, although BGP is especially intended for
multi-homing (more that one uplink/downlink). When you do BGP
you can invent your AS Number but don't advertise your Network outside
your local network. These protocols are all intended to simplify
configuration and maintenance of your routes. For small networks like
less than 5 networks, RIP works well. For complex networks use OSPF
or BGP. Definitely BGP if you have multi-home nodes. For example, your
Albury node sends/receives traffic to/from Canberra, to/from Wagga,
to/from Gundagai, to/from Mebourne, etc, this is BGP routing. In other
words if you use STAR-nodes network definitely BGP.
Hope this helps.
