ospfd

OSPFv2 (RFC 2328) + OSPFv3 (RFC 5340) daemon that programs routes directly into VPP's FIB by pushing them to ribd.

Designed to run inside a VPP-hosted network namespace alongside linux_cp TAP interfaces for packet I/O. Programs VPP's FIB via the binary API, not the Linux routing table.

Build

cargo build --release

Requires a protobuf-free toolchain; depends on vpp-api, ribd-proto, and ribd-client.

Run

ospfd --config /etc/ospfd/config.yaml

Flags:

Flag	Default	Purpose
--config PATH	/etc/ospfd/config.yaml	Config file (see below)
--vpp-api SOCKET	/run/vpp/api.sock	VPP binary API socket
--control-socket PATH	/run/ospfd.sock	Unix socket for query subcommands
--io raw|punt	raw	Packet I/O backend (raw sockets on TAPs, or VPP punt sockets)

Query a running daemon

ospfd query status
ospfd query neighbors
ospfd query interfaces
ospfd query database --area 0.0.0.0 --type router
ospfd query routes

v3 equivalents: status6, neighbors6, interfaces6, database6, routes6.

Configuration

YAML with ospf: and/or ospf6: top-level keys. See examples/ for a minimal config.

SIGHUP re-reads the config and hot-applies changes to per-interface timers (hello/dead/retransmit/transmit-delay), priority, cost, and passive flag; redistribute and summary_addresses are replaced wholesale. Changes to router_id, network type, area membership, or interface add/remove require a daemon restart and are logged as warnings on reload.
