We are pleased to announce FRR release 10.7.0-rc1.

FRR 10.7.0-rc1 is the first release candidate for the 10.7 series, with 1371 commits from 101 developers since FRR 10.6.0. This build is intended for testing; please report issues before the final 10.7.0 release.

Debian and RPM release packages are available under the RC (frr-rc) channels

Thank you to all contributors!

Release Overview

New Features Highlight

  • BFD authentication with keychain support

    • BFD sessions can now use the FRR keychain framework for authentication.
    • Supported algorithms include cleartext, SHA-1, and the meticulous variant required by operators running strict authentication policies.
    • Keychains integrate with BFD profiles and northbound configuration for single-hop, multi-hop, and SBFD sessions.

  • BGP-LS SRv6 extensions

    • BGP Link-State now advertises and processes SRv6 topology information, including:
      • SRv6 Capabilities TLV
      • SRv6 Locator TLV
      • SRv6 SID NLRI (including End, End.X, and LAN End.X forms)
      • SRv6 Endpoint Behavior TLV
      • SRv6 SID Structure TLV
    • Static SRv6 SIDs configured in zebra can be exported into BGP-LS, enabling SRv6-aware TE controllers to consume locator and SID information from FRR.

  • BGP route-map based allowas-in

    • allowas-in can be applied selectively through route-maps instead of only as a blanket peer or address-family knob.
    • This allows finer control over which received routes may contain the local AS in the AS_PATH, improving policy flexibility in complex multihomed and hub-and-spoke designs.

  • OSPFv2 RFC 4222 control-plane DSCP marking

    • OSPFv2 can classify control packets into high- and low-priority queues per RFC 4222 recommendation 1.
    • Recommendation 2 extends the neighbor inactivity timer behavior for low-priority control traffic.
    • Operators can mark OSPF control traffic with DSCP values to protect routing protocol stability under congestion.

  • OSPF BFD quick neighbor

    • When BFD is enabled on OSPF interfaces, a quick-neighbor mode reduces the time needed to bring up OSPF adjacencies over BFD-monitored links.
    • This is useful on fabrics where fast reconvergence after link-up is required.

  • PIM IGMP proxy route-map filtering

    • IGMP proxy joins and prunes can be filtered with ip igmp proxy route-map.
    • A new route-map match condition, match multicast-source-interface, allows policy based on the interface where a join was learned.
    • This helps deployments that proxy IGMP between access and core segments while restricting which groups or sources are forwarded.

  • PIM dense-mode Assert on multi-access LAN

    • Dense-mode wrong-interface traffic on shared LANs now runs the RFC 3973 Assert procedure instead of immediately pruning all neighbors.
    • On point-to-point links the previous immediate-prune behavior is preserved.
    • This elects a single forwarder on multi-access segments and avoids pruning active branches when duplicate (S,G) packets arrive on a non-RPF interface.

  • PIM Auto-RP allow-rp support

    • A new allow-rp configuration accepts Auto-RP groups even when the embedded RP address does not match the local RP configuration.
    • IPv4 and IPv6 Auto-RP are supported through northbound/YANG modeling.
    • This helps mixed-vendor or transitional Auto-RP deployments where strict RP identity checking would otherwise drop valid control traffic.

  • Static route per-route metric and nexthop ECMP weight

    • Static routes now support a per-route metric as a non-key attribute, independent of the existing administrative-distance key.
    • Static ECMP nexthops can carry weights for unequal-cost multi-path forwarding.
    • Together these align static routing policy more closely with zebra’s nexthop-group handling used by other protocols.
