I have a network laid out as follows. The Network ---------- Eth0 - INTERNET x.x.x.x LINUX | Router1 | Eth2 - LAN 172.16.1.x | ---------- Eth1 -Bridge 1a 192.168.1.1 | | ---------- Eth0 - Bridge 1b 192.168.1.2 LINUX | Router2 | Eth2 - LAN 172.16.2.x | ---------- Eth1 -Bridge 2a 192.168.2.1 | | ---------- Eth0 - Bridge 2b 192.168.2.2 LINUX | Router3 | Eth2 - LAN1 172.16.3.x | Eth3 - LAN2 172.16.4.x | Eth4 - LAN3 172.16.5.x | ---------- Eth1 -Bridge 3a 192.168.3.1 | | ---------- Eth0 - Bridge 3b 192.168.3.2 LINUX | Router4 | Eth1 - INTERNET 2 x.x.x.x | ---------- Eth2 - Bridge 4a 192.168.4.1 | | ---------- Eth0 - Bridge 4b 192.168.4.2 LINUX | Router5 | Eth1 - LAN 172.16.2.x | ---------- Currently I do no real routing and use mainly IPTABLES to set rules for forwarding. This worked great until I got a second source, Now I set up virtual interfaces for each person I want to go out INTERNET 2 or eth1 on router 4. I want to use a routing protocol that will allow these routers to speak to each other. I wanted to get feedback on where I could find some GOOD documentation on OSPF or RIPv2. There are large amounts of computers on each LAN and I want the router to determine which line is the best to send the packet out. I would also like the ability to tell it only send certain types of clients out one pipe. Does anyone have suggestions for this. I would like to keep it a little more low maintenance then my firewall scripts I already have. By the way I have swizeet HTB limiting scripts I hope to contribute to the list.
