FRR and libyang2 update
by Donald Sharp 08 Jan '24

08 Jan '24

All -- The latest libyang2 release 2.1.111 has an incompatible change to it's ABI and causes FRR to no longer be able to work properly with it. See this issue filed for an explanation: https://github.com/FRRouting/frr/issues/14258 Additionally it is discussed here: https://github.com/CESNET/libyang/issues/2090 Since FRR needs to make changes to its code in order for FRR to continue to use newer versions of libyang2 it is not recommended that anyone upgrade to libyang2.1.111 or later at this point in time. We currently expect to be able to make these changes for the 9.1 release. What can you do? If you are using FRR 8.0 or later do not upgrade to libyang2.1.111 at this point in time. If you have, please downgrade to 2.1.80 or earlier. thanks! donald

FRR PBR routing by DSCP
by RISTE-SMITH, Robert (External) [UKC] 06 Dec '23

I see there is a new version of FRR is just available that should provide PBR routing by matching DSCP (FRR 9.1). I use Debian version 11 at the moment and plan to upgrade from FRR 7.5 to FRR to 9.1 Will the DSCP match rule work in this platform (some mention about Linux dataplane layer in the FRR documentation)? If not (as I am guessing at the moment) is there some way to configure Debian OS to enable the feature or perhaps a different Linux OS that does support it? I am not a Linux user so would need simple instructions to get this working. Thanks.

Adding local routes via FRR
by Scoopta 05 Dec '23

05 Dec '23

Is there a way to use FRR staticd to add local routes? Specifically I'm looking for an equivalent to the following iproute2 command: ip route add local 2001:db8::/64 dev lo FRR has ipv6 route 2001:d8b::/64 lo table 255 But that command only adds a route to the local table, it does not create a local route which can be used for whole subnet loopback. Thanks
