System information

On my principal router I have:
Point-to-point frame relay to my provider (pvc0)
ethernet for local distribution and routing (eth0)
ifconfig shows me:
pvc0: 169.254.19.13/30
eth0: 10.10.1.1/27
eth0:1 192.168.255.1
routing table looks like this:
10.10.1.0/27 10.10.1.1
10.10.1.32/27 192.168.255.2
10.10.1.64/27 192.168.255.3
10.10.1.96/27 192.168.255.4
0.0.0.0/0 169.254.19.14
What the above says is that the network 10.10.1.0/27 is routed locally. Each of the other 10.10.1.x/27
networks routes to a different radio with IPs on the 192.168.255.0/24 subnet. Default route is out the
frame relay.
Each radio is similar, so looking at one pair of radios is the same as looking at any other pair, just with
slighly different numbers. So the radio 192.168.255.2 on its ethernet interface has no bridges and has
wpc1 of 172.16.2.1. The routing table shows default (0.0.0.0/0) route of 192.168.255.1, and has the
network 10.10.1.32/27 routed to IP 172.16.2.2. (Radios 2 and 3 have IPs 192.168.255.3 and 4 and use
networks 172.16.3.0/24 and 172.16.4.0/24 respectively for routing).
The remote radio has a wpci1 interface of 172.16.2.2 and the ethernet and wpci2 interfaces are bridged
and have an IP of 10.10.1.33. Routing table has only the default route of 0.0.0.0/0 pointing to
172.16.2.1.
Each client radio has an external wpci1 interface on the 10.10.1.32/27 network with default route
(0.0.0.0/0) pointing to 10.10.1.33. All clients use 192.168.100.0/24 as their internal network, NAT to
the external interface, and have dhcp server turned on for their use internally.
The above network is exceedingly easy to expand and can grow without limits. Its implementation is
incredibly easy. Client radios are different only in their external IPs, so only one configuration file is
required and the IP and ESSID changed.
KISS: keep it stupid, simple, is my motto. And by using the above scheme, life is very easy.
Final note: With the exception of the IPs in the 10.10.1.0/24 range, which are really public IPs on my
network, and the frame relay IP, this is a portion of my 20 radio network. Longest chain is 4 radios up
through mountainous terrain. All radios have one or more AP interfaces and one or more backhaul
