BIRD Filter performance improvement: Call for testing
by Maria Matejka 25 Feb '19

25 Feb '19

Hello! We are finishing a significant rework of BIRD filters in 2.0 branch. We dropped the old interpreter and wrote it a bit differently. Currently, our tests are promising at least 10% reduction of the interpreting time; the actual improvement depends on the filter. See the "faster-filters" branch in our git repository: https://gitlab.labs.nic.cz/labs/bird/tree/faster-filters Anyway, reworking a 20-year-old code with almost no documentation and not many tests always yields unexpected bugs. Please try to run your filters on this commit and report if it doesn't work. The frontend and overall behavior should not change in any way -- it should only do it faster. There is a known bug -- we still haven't reimplemented caching of function and named filter comparison results so reconfiguration may take significantly longer time than before on this branch. This will be fixed before merging this branch into master. Thank you for using BIRD, thank you for your testing! Maria

Log limit
by Ticlea Alexandru 21 Feb '19

Hello According to user guide, the next line looks correct but it leads to a syntax error log "/var/log/bird.log" 102400 "/var/log/bird.log-prev" { info, remote, warning, error, auth, fatal, bug }; Can we help me to understand the unit used to express the limit? I use bird 2.0.2

bird 2.0.3 pushes connected routes to kernel
by Kenth Eriksson 19 Feb '19

19 Feb '19

After upgrading from bird 2.0.2 to 2.0.3 we discovered that bird pushes connected routes to the kernel. Tried to alter the preference values for kernel and device, but bird still pushes the connected routes, resulting in duplicate in kernel FIB. How to import connected and kernel routes without bird installing the connected routes again? The only way I found to make it work was by putting an export filter in the kernel like this; export where (source != RTS_DEVICE); Thanks, Kenth

BIRD over internet with static routes?
by dan 17 Feb '19

17 Feb '19

I'm wanting to use BIRD to monitor WAN connectivity of CLIENTS to a SERVER. I'm not familiar with BIRD and I'm relying on RFC5883 description of multi-hop to make my case. I want to set 2 static routes. 1 is a route from CLIENT to SERVER out WAN1. This is the route to be monitored by BFD and it's route distance is 1. The second route is the fall-back, it's not monitored and it's distance is 2 out WAN2. BIRD/BFD's job here is simply to tear down the static route with distance 1. Complication, client's are likely dynamic IP address and also likely behind NAT. The net result is to have a VPN such as wireguard migrate from WAN1 to WAN2 rapidly on WAN1 failure. Wireguard is built to handle this, so ignore complications from changing of src addresses, they are handled. Is this doable and if so, can anyone offer any help with the config? Thanks! Dan.

bfd configuration
by Joel Dahl 14 Feb '19

14 Feb '19

Hi, I've enabled bfd on an iBGP session between two routers. The routers are directly connected, just L2. Taking down the iBGP session (in this case, rebooting the router) results in the following which I find a bit confusing: # birdc show proto BIRD 2.0.3 ready. Name Proto Table State Since Info bfd_ibgp_v4 BFD --- up 2019-02-11 ibgp_v4 BGP --- start 20:59:33.284 Connect Received: Administrative shutdown Why is bfd still in "up" state? Configuration from one of the routers: protocol bfd bfd_ibgp_v4 { interface "igb2" { multiplier 3; interval 500 ms; idle tx interval 1000 ms; }; neighbor X.X.1.6 dev "igb2"; } protocol bgp ibgp_v4 { local X.X.1.5 as 11111; neighbor X.X.1.6 as 11111; bfd on; ipv4 { import all; export all; next hop self; }; } -- Joel

minimal protocols support now needs RIP?
by Leo Vandewoestijne 11 Feb '19

11 Feb '19

Hello, I'm not the FreeBSD port maintainer for bird, however did wrote the initial bird2 port. In there I created the interface to "assemble" which protocols you wish, by un/checking checkboxes. This allows to only support what's needed. That worked all fine untill 2.0.3, but now I get stuck with this: BIRD was configured with the following options: Source directory: .

Unknown instruction 8574 in same (~) Bug
by firas73737＠yahoo.com 10 Feb '19

10 Feb '19

Hello BIRD-users, I am running BIRD version 1.6.3 for about one year now and everything seems to be ok. I've just changed some configuration (set next-hop of a route to some IP address) and then issued a "configure" command at birdc console. That caused bird to exit! I ran bird again with the same configuration and nothing happened this time. I checked logs and found the following:2019-02-10 13:48:12 <INFO> Reconfiguring 2019-02-10 13:48:12 <BUG> Unknown instruction 8574 in same (~)2019-02-10 13:50:27 <INFO> Started What does "<BUG> Unknown instruction 8574 in same (~)" mean? Regards,Firas
