How to Install and Configure RCP100 Routing Suite on Debian 7

Software-based routers have always played a role in the Internet, and are becoming increasingly important in data centers due to the convergence of video, mobile, and cloud services. Data traffic no longer moves simply from the subscriber into the network and then out again. Instead, most of the traffic is located inside the data center between various application servers within the network.

All this traffic can be routed easily using software-based routers running on commodity PC hardware. Such a router looks like just another server in the data center, and most of the time it is implemented using open-source software. The availability of the source code and the right to modify the software enables the unlimited tuning and optimization of the network traffic.

This article describes how to set up RCP100 routing suite on a Debian 7 computer. RCP100 is a full OSPF/RIP router for Linux. It works on 64bit computers, it is licensed under GPL, and it is actively developed.

The computer I am setting up has two Ethernet interfaces, eth0 ( and eth1 (, and it is meant to connect a small private network segment ( to the larger public network. To isolate the private network, I configure Network Address Translation on the router and enable the firewall. Computers on the private network are assigned IP addresses using DHCP. The router also provides NTP and DNS proxy services.

RCP100 Basic Router Configuration on Ubuntu 12.04

I do like the idea of an open-source software router, and I’ve tried several of them so far. Most open-source routers would concentrate on implementing the main IP routing protocols one by one. Administration features like CLI or SNMP seem to get less attention. There is little or no support for integrated Access Control Lists, NTP, DHCP or DNS functionality. This is in sharp contrast with the commercial routers where administration and network management are first class citizens.

RCP100 seems to break the tradition. It has a Cisco-like command line interface (CLI), and all the regular administration and management protocols. Starting with version 0.99 it also features a simple and intuitive web interface, making the router accessible to less sophisticated users and beginner administrators.

In this article I will set up a basic RCP100 IP router on a Ubuntu 12.04 computer using the web interface. This means there will be lots of pictures and no CLI commands. Networking experts will definitely get bored.
