Hi all, We are pleased to announce the 8.1 release of FRRouting. This release brings a long list of enhancements and fixes with 1200 commits from 75 developers. Thanks to all contributors. Packages: Debian Packages - https://deb.frrouting.org/ RPM Packages - https://rpm.frrouting.org/ Snaps - https://snapcraft.io/frr Docker - frrouting/frr:v8.1.0 Some major highlights: * Lua hooks are now feature complete, with one hook available for use * Improvements to Prefix-SID (Type 5) * EVPN route type-5 gateway IP overlay Index * OSPFv3 NSSA and NSSA totally stub areas * OSPFv3 ASBR summarization * OSPFv3 Graceful Restart * OSPFv2 Graceful Restart (restarting mode added, helper was already implemented) Please see the release notes for the detailed changelog: * Github release: https://github.com/FRRouting/frr/releases/tag/frr-8.1 * FRRouting website: https://frrouting.org/release/8.1/ During this period we also hosted an FRRouting 2021 GSOC Project! FRRouting's GSOC student implemented the infrastructure needed to add the ability to call out to user provided Lua scripts from within FRR. Keep an eye out for developments in this area. You can read about the work at: - https://frrouting.github.io/frr-gsoc/year-2021/projects/lua-hook-points - https://dlqs.dev/frr-gsoc-2021.html - Presentation at Netdev 0x15: https://www.youtube.com/watch?v=_8R1MYP7M48&t=1051s Thank you @dlqs!

Problem in FRR with ldpd
by shruti mathure 13 Oct '21

13 Oct '21

Respected Sir, I am Shruti Mathure. I am working on one of the projects related to FRR. I am trying to implement MPLS LDP with FRR in Core emulator. The FRR seems to run but I am having issue with ldpd, It is not running also the staticcd does not seems to run which should automatically start with FRR. I am not able to find the correct solution for it. can you let me know any solution for this if there is any changes or latest updated bugs you have fix. I am not able to find any solution on github. I am using ubuntu 18.04. Thank you, Regards, Shruti Mathure
