Week of 2025-12-22

Extended communities now parse hex format per RFC 4360
ADD-PATH encoding (RFC 7911), including for VPN routes
End-of-RIB markers are now sent for every negotiated address family (RFC 4724)
Extended next-hop encoding per RFC 8950
AS_PATH validation fixed against RFC 5065
IPv6 announcements and withdrawals now correctly use MP_REACH_NLRI / MP_UNREACH_NLRI instead of IPv4-style NEXT_HOP
EVPN routes (all 5 route types) and L3VPN (MPLS VPN) route announcement support
Route Leak Prevention via the OTC attribute (RFC 9234)
Revised UPDATE error handling for malformed attributes (RFC 7606): partial-attribute discard instead of session teardown, plus IBGP-context and 4-octet AS validation
Labeled-unicast (SAFI 4) now supports split announcements, and route announcements support /N split syntax generally
Fixed a bug where withdrawals weren't actually being sent and route stats were wrong
Fixed iBGP attribute handling for API-announced routes

BGP connection collision detection per RFC 4271 §6.8
Backpressure and respawn limits for connected processes, so a misbehaving process can't take down the session

A real command surface for controlling BGP sessions and routes is taking shape:

Session-level commands: status, enable, disable
RIB flush/clear commands
Route commit transactions: named, concurrent commits with announce/withdraw, rollback, and end-of-RIB signaling
Watchdog-controlled routes: named pools of routes that announce or withdraw together, state persisting across reconnects
A teardown command with an ordered operation queue
announce attributes/nlri/update commands with batch NLRI support
Inbound UPDATEs are now forwarded to connected processes
