lowering OSPF memory requirements
by Jack Culpepper 09 Sep '03

09 Sep '03

Hi all, I am trying to use bird's OSPF implementation in a memory contrained linux environment. I have only 2 MB of RAM. Can you give me some tips on how to reduce the memory footprint of bird running OSPF? It is currently using about 1 MB, and I would like to try to cut that by 200 KB or so.. FYI, I am running this on a wireless network. Below I have pasted in my bird.conf file. The 8 wlan0wdsX interfaces are point-to-point wireless links (/30 IP networks) that connect repeaters together. Only the ones with cost less than 1000 are connected. These boxes have 1 ethernet and 1 wlan. Thanks, Jack log stderr all; debug protocols all; protocol static { route 0.0.0.0/0 via 10.96.127.82; export all; } protocol kernel { persist; scan time 20; export all; } protocol direct { interface "eth0"; interface "wlan0"; interface "wlan0wds0"; interface "wlan0wds1"; interface "wlan0wds2"; interface "wlan0wds3"; interface "wlan0wds4"; interface "wlan0wds5"; interface "wlan0wds6"; interface "wlan0wds7"; } protocol device { scan time 10; } protocol ospf { export all; import all; area 0.0.0.0 { tick 8; interface "eth0" { cost 1; hello 15; priority 100; retransmit 7; authentication simple; password "asdfasdf"; }; interface "wlan0" { cost 5; hello 15; priority 100; retransmit 7; authentication simple; password "asdfasdf"; }; interface "wlan0wds0" { cost 44; hello 15; priority 100; retransmit 7; authentication simple; password "asdfasdf"; }; interface "wlan0wds1" { cost 1000; hello 15; priority 100; retransmit 7; authentication simple; password "asdfasdf"; }; interface "wlan0wds2" { cost 1000; hello 15; priority 100; retransmit 7; authentication simple; password "asdfasdf"; }; interface "wlan0wds3" { cost 1000; hello 15; priority 100; retransmit 7; authentication simple; password "asdfasdf"; }; interface "wlan0wds4" { cost 1000; hello 15; priority 100; retransmit 7; authentication simple; password "asdfasdf"; }; interface "wlan0wds5" { cost 1000; hello 15; priority 100; retransmit 7; authentication simple; password "asdfasdf"; }; interface "wlan0wds6" { cost 1000; hello 15; priority 100; retransmit 7; authentication simple; password "asdfasdf"; }; interface "wlan0wds7" { cost 47; hello 15; priority 100; retransmit 7; authentication simple; password "asdfasdf"; }; }; }

bird-1.0.7
by Damjan 01 Sep '03

I just downloaded bird-1.0.7 and it works great but just a small note. In the file sysdep/config.h its still defined as: #define BIRD_VERSION "1.0.6" also "make distclean" deletes the "./configure" script -- Damjan Georgievski

Hello! Sorry, maybe my question is silly but I cannot find an analog of IOS "network" command (i.e. how can I to define my network address range to annouce?). -- WBR, Yury Bokhoncovich, Senior System Administrator, NOC of F1 Group.

BGP and iBGP problem
by Eric Leblond 19 Aug '03

19 Aug '03

Hi, I've got two router link by iBGP. Both maintains two BGP session : BGP1 BGP2 BGP3 BGP4 | | | | RTR1------iBGP----RTR2 BGP2 and BGP4 announce exactly the same thing and I want local BGP announce (with BGP2 on RTR1 and BGP4 on RTR2) to be choozen. The thing is that I get on RTR1 or RTR2 route choozen in iBGP. I try to prepend my AS to the bgp_path but it changes nothing. Any Help appreciated, -- Eric Leblond <eleblond(a)init-sys.com> Alphalink

BIRD & production BGP?
by Chris Halsall 14 Aug '03

Hello all. I'm wondering if anyone has deployed BIRD as a BGP routing daemon in a production environment? Any feedback on it's stability would be appreciated.

Re: BIRD & production BGP? -- Thanks

Hello all. Thanks for the replies to my question -- not seeing nearly as much traffic here as on the Zebra list, I was concerned that no-one was using it in a production environment. Does anyone have an opinion on how Bird compares to Zebra? And as far as developer support, the Bird team seems fairly small (but quite competent). Are issues dealt with well, or is it a self supported type arrangement? I'm comfortable programming and debugging in C, but it would be nice to know there's a good support network as well. And considering one of the machines we're proposing to use this on will be quite some distance away, we'd obviously like to have a stable system. Best regards. -Chris -- Chris Halsall, Chief Technology Officer chalsall(a)wamcodm.com Wamco Technology Group Ltd. http://www.wamcodm.com/ #3 Mahogany Court, Wildey, St. Michael Barbados Phone: 246.437.3154 FAX: 246.228.4319 "Every wave in the universe has its own integrity." - Buckminster Fuller "So what I want to know is: is time long, or is it wide?" - L.
