Another RIP problem...
by Mario Lorenz 21 Jun '00

21 Jun '00

Its getting late, or rather to say early now, and I am tracing sporadic dials on my setup. What I have seen so far is that they are caused by sporadic loss of the RIP route. Sporadic in this case means always after timeout/garbage timer run. Debug says it kicks the route out because it is too old, and a couple second later it is back in, most likely from the next broadcast. Bird is getting the broadcasts. In "show route", said RIP route has an updated timestamp, and that one gets updated each time a broadcast happens and the bird log says > ignored ... (because its already there). A quick examination of the source shows that in this "ignored" case, the lastmod timestamp gets updated, which is what show route shows. But the route gets cleaned out according to the lastmodX timer, which does not get updated. Is this a bug or is that mandated behaviour (which I doubt, since it is silly & causes routing instability...) ?

RIP Metric export to kernel table ?
by Mario Lorenz 20 Jun '00

20 Jun '00

Hi list, I was just looking for a more configurable RIP engine than routed is, when I came across bird. bird seems fine for all I want to do, except one problem: It does not export the RIP metric of routes it receives to the kernel. Or may be I am just too stupid to do it, given that I couldnt get zebra to do it either. With stock routed it works, however. The application I have for this is a VPN with a dial-on-demand modem backup. In order to make the ppp link being used if its up, I need to control the metrics differently for the links. That works fine with bird filters, and the rip announcements do carry the correct metric (i set it to 5), according to tcpdump. However on the other end, the routes show up with metric 0 in the kernel table, which of course disturbs the settings I planned for it. What am I doing wrong ?

Where might I find some information about the bird client? Scanning the client source code didn't really help and: configure: error: The client requires GNU readline library 2.1 or newer. Either install the library or use --disable-client to compile without the client. makes it difficult to read the on-line docs.

One of the handy Cisco IOS routing commands is to display the protocol neighbors. That allows troubleshooting determination if the other router is "listening". You might want to consider adding that feature to the client.

BIRD taking 50% CPU with RIP and 90 Routes
by Florian Lohoff 18 Jun '00

18 Jun '00

Hi, i have seen a very high load produced by bird on one of my machines. I am basically using the beneath config. I think it has something to do with a misconfigured device not having enabled Split Horizon. The Ascend Max announced the local ethernet ip address so bird deleted the local ethernet route but couldnt add the route with a gateway because the kernel returned "host unreachble". With this configuration and 12 hours runtime the process grew to 25MB (With only ~90 Routes) and took at least 50% CPU time. Somebody got an idea ? Due to a braino myself the machine is now - aehm - unreachable and about 400km away - I have to get someone to reboot then ill send logfile output. ----------- log syslog { info, remote, warning, error, auth, fatal, bug }; protocol kernel { scan time 120; export all; } protocol device { scan time 120; } protocol rip ripd { debug all; interface "eth0" { mode quiet; mode broadcast; }; honor neighbor; authentication none; import filter { print "importing"; accept; }; export filter { print "exporting"; accept; }; } --------------------------------- Flo -- Florian Lohoff flo(a)rfc822.org +49-waiting-4-telekom "If you're not having fun right now, you're wasting your time."
