We maintain a set of reference documentation for users looking to run FRR. We also maintain a reference for current and aspiring FRR developers which documents many aspects of our development workflow in addition to the FRR process architecture and some data structures common across FRR daemons.

Both sets of documentation are recommended-reading before using or contributing to the FRR repository on GitHub.

• User Guide
• Developer Documentation

Many FRR daemons are periodically tested for compliance with their respective RFCs. These reports are publicly available below and demonstrate FRR’s capabilities as a full routing suite.

• RIP | RIPNG
• OSPF | OSPFv3
• ISIS | ISISv6
• BGP4 | BGPPLUS | BGP-AS4 | BGPPLUS-AS4
• LDP
• PIM
• IGMPv2
• IGMPv3

Vulnerabilities discovered by the FRR team affecting older versions of FRR are patched and documented using CVEs. A list of CVEs and the FRR versions they relate to is documented here.
