FRRouting

FRR is free software that implements and manages various IPv4 and IPv6 routing protocols. It runs on nearly all distributions of Linux and BSD and supports all modern CPU architectures. The project website is frrouting.org.

FRR currently supports the following protocols:

• BGP
• OSPFv2
• OSPFv3
• RIPv1
• RIPv2
• RIPng
• IS-IS
• PIM (SM, DM, SSM, MSDP)
• LDP
• BFD
• Babel
• PBR
• OpenFabric
• VRRP
• EIGRP (alpha)
• NHRP (alpha)

Not every protocol or feature is available on every platform; see the feature matrix in the user guide.

Centralized FRR configuration (work in progress): the mgmtd daemon applies YANG configuration to the routing protocol daemons through the northbound API (instead of each daemon only having its own legacy configuration path). Not all daemons are migrated yet; expect ongoing changes. See mgmtd in the user guide.
