no soft bgp clear is triggered on modification to prefixlist / routemap
by François 02 Aug '18

02 Aug '18

Hello, This issue has been discussed here : https://github.com/FRRouting/frr/issues/126 To sum up, when a route-map is modified (tried 2 things: adding a new entry and modifying prefix-list involved), no soft bgp clear is performed, so it looks like other peers never get new results (the "show advertised route" output is correct). Looks like "no route-map ... " and "route-map ..." again does the trick. My question is: do someone has an idea on how to fix that? I can give a shot, but I would appreciate some inputs ;) Ps: I use version 2 of FRR (because Vincent Jardin told that version 3 was not production ready at FRNog 29 ;)) Thanks! -- François

Hi folks, Updated documentation is now on the FRR website. User guide: https://frrouting.org/user-guide/ <https://frrouting.org/user-guide/> Developer’s guide: https://frrouting.org/dev-guide/ <https://frrouting.org/dev-guide/> This was built from the tip of master and should be accurate for the upcoming 4.0 release. Eventually I will work on a way to publish versioned documentation for each release. The developer documentation will be rolling. Thanks, Quentin

`default` keyword?
by Donald Sharp 31 Mar '18

31 Mar '18

So currently if you want to specify the default vrf as a string you have to use: Default-IP-Routing-Table Do people have opinions on what to use? I am thinking of making the keyword `default` special in that it will allow lookup of the default vrf if entered. thoughts? doanld

Question about EVPN route types
by Jay Chen 30 Mar '18

30 Mar '18

Hi all, I got a question about what EVPN route types are supported already in the latest version. It looks like type-2, type-3, and type-5 are supported. Type-1, and type-4 are not yet. If it is true, any plan the missing types are going to be supported? Another quick question, the fpm/fpm_pb.c file looks empty. Is there a missing patch need to be patched? It will be very helpful if anyone can point to a brief example how fpm is used by a switch that has a hardware forwarding path? Thanks, Jay

C99 fixed-width patch
by Quentin Young 28 Mar '18

28 Mar '18

Hi folks, PR #1854 switched all of our fixed width types over to types present in the C99 standard. Since we used a lot of nonstandard types this was a pretty big patch and may have caused conflicts with open pull requests or your private branches, so you may want to check. If you’re using these types in some new code, you can try using the conversion script in tools/convert-fixedwidth.sh followed by a `git clang-format` to replicate the process that was done to master and hopefully reduce some of the conflicts.
