Quagga Project

Project Description

Quagga seeks to integrate the open-source Quagga routing suite as is currently found in Solaris 10 under /usr/sfw – the SFW consolidation. The Quagga routing protocols include:

• Open Shortest Path First (OSPF) and OSPF6 protocols
• Border Gateway Protocol (BGP)
• Routing Information Protocol (RIP) and Routing Information Protocol next generation (RIPng)

All Quagga protocols support both IPv4 and IPv6 addressing.

Quagga is a fork of GNU Zebra. The version of Zebra currently in sfw – SUNWzebra – is based on GNU Zebra 0.92a, with many fixes, particularly to 'ospfd'.

Quagga differs from Zebra in that it provides:

• Ability to run with least privileges
• Innovative 'route-server' feature for BGP
• OSPF-API feature, which is an API to allow applications to observe the OSPF 'fabric' and even inject their own LSAs

Quagga's main feature, however, is that it has built a healthy open-source community around the original GNU Zebra codebase, the lack of which was probably the worst deficiency of GNU Zebra.

Quagga is widely used, bundled in Debian and Fedora Linux distributions and NetBSD. Approximately 2000 downloads of Quagga 0.98.2 occured in March 2005 alone. Given that routing is offered at level 1 support, having an up-to-date product with a dedicated community is vital.

To integrate Quagga (and its SMF manifests) nicely with OpenSolaris, we intend on SMF-ifying routing management in Solaris. This is the part of the project that effects the ON consolidation.

Quagga's Current Status

The Quagga project integrated into OpenSolaris/ONNV build 53, and into SFW in SFWNV56. As such Quagga will be usable in build 56, and will replace Zebra there.

The design document for this phase is here

It's changed somewhat from the original design posted on networking-discuss, thanks to internal and external feedback.

We have launched the code review for the ON changes, see the networking-discuss thread, code review swamp.

These changes make routing management manageable via SMF, so you can do things like:

$ svcadm enable ipv6-forwarding

to enable ipv6 forwarding

$ svcadm enable ripng:default

to enable in.ripngd

and so on.

In addition, service conversions for in.routed, in.ripngd, in.ndpd and in.rdisc are provided, and we split out the routing components of the network-initial service into a new network-routing-setup service.

You can see manpages for routeadm/quagga here

How Can You Get Involved?

In a number of ways.

• Work with the quagga community, fixing bugs etc. We'll be integrating the latest available version of quagga as-is, so obviously the more bugs that are fixed, the better. Paul DOT Jakma AT sun DOT com will be able to point you at work that needs doing here.

• Work on the ON changes required to support routing management (webrev of latest code above). Alan DOT Maguire AT sun DOT com will be able to help here.

• In addition, we've got some ideas for followup work, some of which would make nice bite-size projects. Paul or Alan can help here.
