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

BGP Route Leaking for VRF-Lite and VPN's
by Donald Sharp 15 Mar '18

15 Mar '18

All - During discussions this morning w/ Lou we discovered that we are both working towards a BGP solution for Route Leaking. We have enough differences between our approaches that we need to spend some time consolidating our approach. The current plan is to have the meeting at 3:30 EDT this Friday Jan 19. If you would like to attend please let me know and I will put you on the invite for it. donald

Manpage content
by Quentin Young 01 Feb '18

01 Feb '18

Hi folks, As part of the work I’m doing to convert all of our docs to RST, I’ve now reached the point where I am converting over the manpages from groff and want some community input on content. As it stands the manpages have not been significantly updated since ~2004 and contain little more than a brief summary of option flags. Now that all of the user documentation is in RST, as far as I can see we have two options: 1. Keep the manpages separate, with their current minimal content. Example (converted) manpage source: (bgpd.rst) http://ix.io/F0E <http://ix.io/F0E> (common-options.rst) http://ix.io/F0G <http://ix.io/F0G> 2. Add the standard SYNOPSIS, DESCRIPTION, OPTIONS etc. sections, as in the source above, to the top of each chapter in the user documentation that covers a daemon, and then generate manpages from the same source we use to generate the various other manuals (web, info, pdf, etc). The only downside I see to option #2 is that some of the manpages have small novels written inside them (for example the 24 paragraph section on MED in the BGP chapter), which degrades their usefulness as the “quick reference” people tend to use them for these days. Whereas the upside is 13 less (albeit small) files to update when things change and a significant increase in the amount of overall information in the manpages. Thoughts?

AT&T to Release “dNOS” Software Framework Into Open Source to Accelerate Network White Box Adoption
by Olivier Dugeon 31 Jan '18

31 Jan '18

Hi all, Do you see this news: http://about.att.com/story/dnos_software_framework_into_open_source.html As AT&T mention the asset of Vyatta, do you know if they continue to use Quagga or if they have switch to FRR ? Perhaps it is time to contact AT&T as in their previous white paper about dNOS, they are very criticism against Quagga. Regards Olivier
