Question regarding interaction between custom protocols and OSPF tables
by Adam Schultz 12 Nov '15

12 Nov '15

Is it possible to advertise routes from a custom protocol via OSPF as an internal route type instead of external-1 or external-2? The use case is an application that does not use the kernel routing table and needs to inject routes into OSPF. To do this, I'm experimenting with a custom protocol that communicates with the application and imports the routes for me. Unfortunately, since the routes in the common table appear to come from my protocol instead of OSPF, they're exported as external which distinctly not the desired behavior. Thanks for any help or advice you can provide, Adam

Re Hello, Looking into this commit, https://gitlab.labs.nic.cz/labs/bird/commit/11fabd2d6b8bc3d6ca86acd3b62fe4d… I hope it doesn't mean that you will be removing BGP UPDATE dumps to add the RIB dumps. Will both be supported? Thanks Evelio

bird: KIF: Invalid broadcast address 255.255.255.255 for em1

Hi Fellow BIRD users, It appears that BIRD does not fully appreciate RFC3021 style addresses on Ubuntu 15.04, when I start BIRD: syslog:Nov 10 15:25:15 eunetworks-2 bird: KIF: Invalid broadcast address 255.255.255.255 for em1 syslog:Nov 10 15:25:15 eunetworks-2 bird: KIF: Invalid broadcast address 255.255.255.255 for p2p2.1003 syslog:Nov 10 15:25:15 eunetworks-2 bird: Started root@eunetworks-2: # ip -4 addr show dev em1 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 inet 94.142.247.237/31 brd 255.255.255.255 scope global em1 valid_lft forever preferred_lft forever root@eunetworks-2: # ip -4 addr show dev p2p2.1003 14: p2p2.1003@p2p2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default inet 78.152.32.177/31 brd 255.255.255.255 scope global p2p2.1003 valid_lft forever preferred_lft forever Should I configure the Linux side of things differently or is this something that needs resolving in BIRD itself? root@eunetworks-2:~# uname -a Linux eunetworks-2 3.19.0-32-generic #37-Ubuntu SMP Wed Oct 21 10:23:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux root@eunetworks-2:~# dpkg -l | grep bird ii bird 1.5.0-1+vivid+1 amd64 Internet Routing Daemon root@eunetworks-2:~# lsb_release -a No LSB modules are available.

Hello! We quite successfully use Bird in our infrastructure and now want to expand it. I would like to know how it will behave in the following conditions are met: 4 BGP full view 70 Bird ospf routers in the same area 10000 ospf routes Did someone experience in the deployment of such a scheme and whether there were any difficulties or problems? -- Razin Ivan

'Aggregate' pipe protocol - is it planned?
by Andrew 10 Nov '15

10 Nov '15

Hi all. IMHO it'll be good to have 'aggregate' protocol (like 'pipe' one) for route count decreasing in system routing table (which results in routing performance increase)) and for using bird server as routing server for hardware routers/L3 switches which usually have not too big TCAM. Is such protocol planned for future?

Route update question
by Jigar Mehta 31 Oct '15

31 Oct '15

I am using my own protocol and wanted to understand more about handling of route update. When my protocol receives a route, I inform the core using rte_update() and pass on the new route and when I need to delete I set new = NULL and call rte_update(). Problem : 1. This is the initial route that was installed in the table. Route1 10.0.1.0/24 Metric : 10 2. Received a better route with Metric as 5, so i call rte_update and pass on the new route. So now, I have Route1 10.0.1.0/24 Metric: 5 3. Protocol again receives an update to delete the cost 5 route (step 2) . However when I do that, I see that I no longer have any route to 10.0.1.0/24 instead of having a higher cost route (cost 10 ). When I enable debug, I see that during delete, when we fall through rte_recalculate() in core code, net->routes is being set to null and so we never do recalculation for new optimal route. Is there something I need to do after we call rte_update() to install route so I save the old_best route. Thanks, -- Jigar Mehta

bird 1.5.0-4 ospf Inactivity timer expired.
by Andrey Kitsul 29 Oct '15

29 Oct '15

Hello, I have three Ubuntu physical machines with quagga (ospf area0/bgp with full route table on 2-4 uplink) and one whit bird (ospf only). On one of the routers (ospf/bgp) replace quagga on bird. Configuration bird attachment. After replacing the CPU load there is increased by 10-15%. On top Bird periodically consumes up to 90% of the CPU, and at a given time is restarted ospf: Inactivity timer expired for nbr. On one interfaces eth1.2508 to another bird router, I increased the Dead interval to 10 seconds. And it helped. What could be my problem? Large filters BGP, smallest ospf hello/dead interval or something else? One of restarts occurred at 13:13:13, OSPF trace in attachment, OSPF net packet in attachment. -- Кицул Андрей администратор Unix-систем ЗАО "НГС" +7-923-111-3940

Hi. Just got a build failure with recent gcc with enabled option FORTIFY_SOURCE=2: In function 'strncpy', inlined from 'rip_outgoing_authentication' at ../../../proto/rip/auth.c:134:5: /usr/include/bits/string3.h:120:10: error: call to __builtin___strncpy_chk will always overflow destination buff er return __builtin___strncpy_chk (__dest, __src, __len, __bos (__dest)); ^ make[1]: *** [auth.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make[1]: Leaving directory `/usr/src/RPM/BUILD/bird-1.5.0/build-bird6/proto/rip' make: *** [subdir] Error 2 make: Leaving directory `/usr/src/RPM/BUILD/bird-1.5.0/build-bird6' There is proto/rip/auth.c:134: strncpy( (char *) (&block->packetlen), passwd->password, 16); destination packetlen is u16, so gcc thinks it is overflow.
