bgpd/bgp_mplsvpn.c change
by Donald Sharp 12 Dec '18

12 Dec '18

Anton - Recently you had e23b9ef6d2 committed into FRR. During subsuquent testing it was noticed that this change broke various forms of route-leaking. In order to preserve current functionality, we have backed this commit out. My apologies for not catching these issues earlier on initial submission. In the meantime, we've added new tests to the topotests to catch this problem from happening in the future( see tests/topotests/ bgp-vrf-route-leak-basic and bgp_l3vpn_to_bgp_vrf ). Lou and I believe that your initial approach was probably the right thing to do but it needs to not break existing functionality. What was the use case you were needing this change for? donald

Reg: FRR PBR Configuration
by valli rama 04 Dec '18

04 Dec '18

Hi, We have the below setup with RIP and PBR configurations [image: image.png] We have RIP default learned for 192.168.57.0 and we are trying to install the PBR Policeis with the Next-hop 192.168.58.0 (other than the default one) Step -1 First we are trying to install the PBR Policy “One” with Sequance Number “1” and binded it to an interface on both the FRRouters A and B [image: image.png] Step -2 And we observed that the Traffic is redirected to the Nexhop given in the policy. Which is working Fine. Step -3 Now we are trying to update and re-install the PBR Policy “One” with Sequance Number “2” and bound it to the same interface on both the FRRouters A and B [image: image.png] [image: image.png] Step-4 We observed that the Traffic is NOT redirected to the Nexhop for Policy with Sequance Number “2”. As per my understanding both the Policies Seq “1” and “2” are belongs to same Policy-Map and Binded to the Interface and Both should work as per the Policy Rules... But Rule with Sequance Number “1” is working as per the Policy Rule But Rule with Sequance Number “2” is not working. Could you please guide me whether I’m missing any configuration steps that should be considered for getting the above stuff working. And could you please let me know how to check the corresponding insalled iptable entry in the linux kernel for the configured FRR PBR policy. Thanks and Regards, Valli

IPv4 public address with country code
by Owais Ahmad 02 Dec '18

02 Dec '18

Hi All, Can someone guide me how I can achieve following implementation ? I don’t have high class computer science education or university degree so that’s why apologies in advance if following seems Inappropriate or something like that. I just have this question in my mind which I want to clear. I am not big fan of IPv6 so that’s why want to extend functionality of IPv4. I want to have IPv4 all public addresses assigned to each country. It’s like I want to subnet total of Public live IP to each with their country code prefix. Let’s say 216.58.207.238 for Latvia it should be 216.58.207.238*.371* For US it should be 216.58.207.238.*1* End user when he want to handle IP based communications he should know the live/public IP and suffix of that country where servers is hosted Ping 216.58.207.238*.371* otherwise router which on the edge network with custom routing protocols should at least knows default zone when no suffix is assigned. Then it should automatically this append suffix it to requested IP address User pings ping 216.58.207 and router replies Ping 216.58.207.238.*1* Same is case with DNS based communications. When user Ping google.com.lv # the DNS server should automatically resolve it on base of suffix and add country code to it Ping 216.58.207.238.*371* Otherwise DNS server should automatically add country code of default/current region IP address to it e.g. if there is no google.com server hosted in Latvia it should append Germany code to it Ping 216.58.207.238.*49* These are things are mainly to be handle by routing protocol beside DNS resolving job. Also subnetting and NAT/PAT stuff remains same for each country under the umbrella of whole world`s public IP assigned to them. Even end users device seems to be independent of knowing the change. One if thing which is also great is from security point is that IP masking will be difficult as router will miss handle the communications if device with suffix of Latvia is placed in Germany. Please do let me know if any flow diagram required and comments Even bad ones are welcomed. Thanks in advance. Owais.

FRRouting: SQLite for OSPF and ISIS database, BGP link-state, Devel-tools
by Ehsan Sabooni 17 Nov '18

17 Nov '18

Hello dear all, I am pretty new in FRRouting, and keen to take part in its usage and development. I have started reading ISISd code. I saw somewhere in the code, and I thought whether it is possible to have the ISIS/OSPF database to be saved in SQLite database; making it pretty easy for further developments, such as developing CSPF and RSVP-TE for it. my question is: 1- does FRRouting save ISIS/OSPF database information in SQLite database? 2- If not, how is it possible to force it to do so? 3- Does FRRouting support BGP link-state protocol? this make it suitable for carrier level provisioning via SDN solutions (OpenDaylight, ONOS). 4- That's my shy for asking such unprofessional question at last, if I want to start development and contribution, where should I start? (Which IDE, development tools, etc, do I need?). as a C developer the only tool that I know to read and understand the C code, is Cscope. Do you have any other recommendation to speed up my work? I appreciate your support! thanks and best regards.,,

Discussion call about interface naming <> namespace VRF next Monday 14:00 UTC
by David Lamparter 14 Nov '18

14 Nov '18

Hi all, Philippe and I are setting up a call to talk about interface naming considerations in the face of namespaced VRFs, i.e. when names aren't unique anymore. This is related to PR #3246 for the distribute list use case. We'll hop on the usual Bluejeans: https://bluejeans.com/9192742159/ Monday 19th at 14:00 UTC (6:00 PST / 9:00 EST / 15:00 CET / 19:30 IST) Per usual, everyone is welcome to attend, if anyone with knowledge of the BSD network stacks is around that would be especially cool. Cheers, -David

A quick question about RFC 5512?

I have a question to FRR BGP exports, what is the status regarding RFC 5512? Thanks, Jay From: dev <dev-bounces(a)lists.frrouting.org> on behalf of Donald Sharp <sharpd(a)cumulusnetworks.com> Date: Wednesday, October 24, 2018 at 6:09 AM To: "tamar_c(a)rad.com" <tamar_c(a)rad.com> Cc: "arik_p(a)rad.com" <arik_p(a)rad.com>, FRRouting-Dev <dev(a)lists.frrouting.org>, frog <frog(a)lists.frrouting.org> Subject: Re: [dev] [FROG] Multicast Protocol The `show ip multicast` command is showing that pim does not think vpp0 or vpp1 have an ip address or an associated VIFI in the linux kernel. I would recommend trying this again: conf t interface vpp0 no ip pim sm ip pim sm ! interface vpp1 no ip igmp join 224.1.1.1 3.3.3.4 no ip pim sm ip pim sm ip igmp join 224.1.1.1 3.3.3.4 ! Then let's re-issue a `show ip multicast` and see if those interfaces are now configured under pim. If not we can discuss debugging. I would also recommend joining the FRRouting slack for a real-time debugging ability. donald On Wed, Oct 24, 2018 at 8:17 AM Tamar Cohen <tamar_c(a)rad.com<mailto:tamar_c@rad.com>> wrote: Hi Donald and thank you!!!!

There is no good way to have asynchronous logging data between all the daemons be sent to the vtysh process for what you are trying to do. I would suggest using a `log file XXX` and in another window tail'ing that file. I have also been known to turn on debugging, watching the log file via a `tail -f XXXX &` and then invoking vtysh to see output as I do work. 3) this is the same question as #1, so yes. donald On Wed, Oct 24, 2018 at 7:34 AM Tamar Cohen <tamar_c(a)rad.com<mailto:tamar_c@rad.com>> wrote: Hi all, My name is Tamar and I have the release 5.0.1 of the FRRouting, it is an excellent IP routing protocol suite!
