One BGP session flapping but not the other
by Alarig Le Lay 23 Dec '17

23 Dec '17

Hi, I have a pretty simple design: two edge routers, one hypevisor. The routing is done with the help of BGP. regis is the hypervisor. +---------+ +-------+ | nominoe | | budic | +---------+ +-------+ \ / \ / \ / AS204092 --------\-------/--------- \ / AS65000 +-------+ | regis | +-------+ The IPv4 session between nominoe and regis is flapping, but not the one with budic. The IPv6 sessions are stables. nominoe and budic are FreeBSD 11.1-RELEASE boxes, running bird 1.6.3 regis is a gentoo box running bird 1.6.3 too At each time the session is flapping, I can see 'bird: Kernel dropped some netlink messages, will resync on next scan.' in the logs of regis. What does that mean, and what part of the configuration is acting on it? The sessions are configured the same maner at the edge side: template bgp DOWNSTREAM { export all; import keep filtered; } protocol bgp bgp_alarig from DOWNSTREAM { local as 204092; description "BGP for alarig"; neighbor 89.234.186.100 as 65000; import keep filtered; import filter bgp_filter_customer_alarig_in; } And the same goes for the hypervisor: template bgp UPSTREAM { local as myasn; # Be able to see filtered routes with "sh route filtered" command import keep filtered; # Protect ourselves from massive routes leaks receive limit 700000 action block; # Announce only our IP allocations export where proto = "static_alarig_allocations"; export limit 1 action block; } protocol bgp bgp_nominoe from UPSTREAM { description "nominoe"; neighbor 89.234.186.7 as 204092; # Local address we use to establish the BGP session source address 89.234.186.100; # password='' # Accept all routes from Cogent except bogons and other bad stuff import filter bgp_filter_nominoe_in; } protocol bgp bgp_budic from UPSTREAM { description "nominoe"; neighbor 89.234.186.6 as 204092; # Local address we use to establish the BGP session source address 89.234.186.100; # password='' # Accept all routes from Cogent except bogons and other bad stuff import filter bgp_filter_budic_in; } I can paste the rest of the configuration if you think it’s relevant. Thanks, -- alarig

Protocol direct
by Miłosz Oller 23 Dec '17

23 Dec '17

Hi In bird 2.0 protocol direct works correctly? New config: protocol direct { ipv4; ipv6; interface "*"; } And it doesn't announced any local prefix to upstream peers, only to ibgp peer. -- inż. Miłosz Oller

vmtoolsd 100% CPU with bird6
by Andrea Verni 21 Dec '17

21 Dec '17

Hi guys, I noticed that the VM where I have deployed BIRD is having ~5 sec of 100% cpu used by the "vmtoolsd". This started to happened since I introduced a IPv6 peering (full table). I found a discussion where someone was suggesting to set the poll-interval=900 in the 'tools.conf'. I did that but still see the CPU sometime overused. Is there fix for that (I would prefer not to go to bird2.0 yet). Thanks! Andrea

Bird 2.0 AS path prepending
by Daniel Czerwonk 20 Dec '17

20 Dec '17

Hello bird users, I just started to test bird 2.0 and converted the existing bird 1.6 configuration to bird 2.0. I compiled bird 2.0.0 on my fedora test VM and got it running. But when I use path prepending in BGP (the same way I did in 1.6) bird throws an error and does not export the route. Does anyone have the same problem? Thanks, Daniel Configuration: template bgp generic_bgp { local as 202739; enable route refresh on; keepalive time 10; hold time 30; } protocol bgp vultr from generic_bgp { neighbor 2001:19f0:ffff::1 as 64515; ipv6{ next hop self; import keep filtered; import filter upstream_as64515_in; export filter upstream_out_test; }; multihop 2; password "xxx"; } filter upstream_out_test { if net = 2001:678:1e0::/48 then { bgp_path.prepend(202739); bgp_path.prepend(202739); bgp_path.prepend(202739); bgp_path.prepend(202739); accept; } reject; } Log: Dec 20 17:47:51 bb1 bird[1370]: filters, line 110: Can't prepend to non-path

Bird 2.0.0 and reconfiguring
by Miłosz Oller 20 Dec '17

20 Dec '17

Hi Why bird restart all sessions when I type 'configuration soft' in birdc after add one definition of protocol bgp? CPU usage is 100%, bird console hang for 2-3mins. With version 1.6.3 bird doesn't restart all sessions. -- inż. Miłosz Oller

I'm testing the Bird2.0 version, but I've couldn't find how to enable the session using VPN4 and VPN6 The BGP Example posted in the user's guide, only has configuration of IPv4, IPv6 and Ipv4Multicast. Does anyone has tested this feature?. Regards.
