Re: [bird-support #905971] bird.network.cz on HTTPS

Dear Webmaster(s) for the BIRD project Q: Is there any consideration for moving the project homepage to HTTPS ? Currently the homepage for the HTTPS enabled edition is just the defailt Apache2.4 installation page on Fedora https://bird.network.cz/ -- "This page is used to test the proper operation of the Apache HTTP server after it has been installed. If you can read this page, it means that the web server installed at this site is working properly, but has not yet been configured."

Routing between BGP Sessions
by Matthias Merkel 17 Jun '18

17 Jun '18

I have a Debian server which has multiple BGP sessions established via BIRD. I'm not trying to make it so that the server acts as router between these sessions (meaning it would redistribute the routes it receives from peers and route incoming traffic from peers to the peer the IPs are announced by). My config can be found at https://hasteb.in/soxeyago.nginx As this is a test system the peers are connected via GRE. I have replaced the passwords with PASSWORD GOES HERE.

BGP Connection reset on fast timers
by saksham 15 Jun '18

15 Jun '18

Hi All, I am testing BGP stability with extremely aggressive timers. The timers are 1/3. I see BGP flapping 2-3 times every 24 hours. Attached is a packet capture, captured on the system running bird. 10.194.8.11 is a Cisco ASR. 10.194.8.13 is the running bird instance. I see multiple keep-alives coming in from .11, but the bird instance responds with hold timer expired. This was about after 12 hours in established state. Connection opens right back up again. I don't see the same issue on upping the timers to 3/9 seconds. Anyone see anything like this before? Thanks, Saksham

BGP: AS private number check
by Arvin Gan 15 Jun '18

15 Jun '18

Hi All, According to RFC1930, the AS number 64512 to 65535 are reserved for private, I cannot find the implementation for checking private AS number in BIRD, anybody know it or it's lost in BGP ? RFC1930 10<https://tools.ietf.org/html/rfc1930.html#section-10>. Reserved AS Numbers The Internet Assigned Numbers Authority (IANA) has reserved the following block of AS numbers for private use (not to be advertised on the global Internet): 64512 through 65535 Thanks Arvin

Dear MO, Thank you very much for your response. Yes, I followed the sample to set up the routers but don’t why the peering session between them is not established.

RE: BGP keepalive_time
by Arvin Gan 13 Jun '18

13 Jun '18

Hi all, Anyone meet the issue as below reason that cause BGP hold timer timeout (keepalive_time > hold_time) and switch action between closing and opening session? Thanks Arvin From: Arvin Gan Sent: Friday, June 08, 2018 3:22 PM To: 'Ondrej Zajicek' <santiago(a)crfreenet.org> Cc: bird-users(a)network.cz Subject: BGP keepalive_time Hi all, When I used bird, found a question that BGP session received OPEN message, hold_time is updated with min(config_hold_time, peer_hold_time), but keepalive_time is not updated if keepalive_time is not zero, that maybe cause keepalive_time is more than the updated hold_time after received OPEN message. Line 702 in packets.cc for bgp protocol : conn->keepalive_time = p->cf->keepalive_time ? : conn->hold_time / 3; RFC 4271: 4.4. KEEPALIVE Message Format BGP does not use any TCP-based, keep-alive mechanism to determine if peers are reachable. Instead, KEEPALIVE messages are exchanged between peers often enough not to cause the Hold Timer to expire. A reasonable maximum time between KEEPALIVE messages would be one third of the Hold Time interval. KEEPALIVE messages MUST NOT be sent more frequently than one per second. An implementation MAY adjust the rate at which it sends KEEPALIVE messages as a function of the Hold Time interval. Thanks Arvin
