By default, rVRRPd reads the /etc/rvrrpd.conf configuration file. This file holds all the configuration elements needed for the proper operation of the daemon, the virtual routers, and their related functions.

At this time of writing, both TOML (default) and the JSON formats are supported for the main configuration file. The former is usually simpler to understand and to write, greatly reducing human errors. JSON based configurations however, are harder to write and to parse for some people, but may be more practical when used with automation tools or with an HTTP based Application Programming Interface (API).

If you don’t know which configuration file format to use, we recommend to stick with TOML, unless you want to use the Client API extensively.

The rVRRPd daemon runs one virtual-router per interface, group pair, which means you can configure the same VRRP groups id or virtual-router id across several physical interfaces. The daemon can scale to hundreds if not thousands of active virtual-routers if the CPU and memory resources permit.

The initial developer of rVRRPd has chosen to build the daemon entirely using the Rust programming language. Rust is a language, aimed primarily at security and speed. You get all the benefits of a modern object-oriented programming language such as Java or C++, without their respective performance penalty and inherent security risks.

We tried to keep unsafe blocks as small as possible in order to provides a clean interface to unsafe functions. However, we cannot removes all of them as they are necessary to implement functions calls to the standard C library, and to the various interfaces (such as IOCTLs) to the operating system kernel.

We hope that you will enjoy running rVRRPd and you would be able to solve your current network and high-availability challenges in less time and thus without the hassles commonly found in commercial solutions.

This project wouldn’t be live without the dedication of its developers, and the open source community. Any contributions are greatly welcome, and will help us developing new features and a more stable and secure implementation.

You can help us directly by donating to the project.

Every single penny will cover the development cost of rVRRPd, which is comprised of a lot of coffee, and the power bill of the bare-metal servers running the interoperability and testing labs.
