VTI route not set
by Alexander Velkov 18 Apr '18

18 Apr '18

Hello, I configure a VTI interface with 'ip link add vti0 type vti local aa.bb.cc.dd remote aa.bb.cc.de' # bird --version BIRD version 1.6.4 # ifconfig vti0 vti0 Link encap:UNSPEC HWaddr C0-A8-03-03-00-00-00-00-00-00-00-00-00-00-00-00 inet6 addr: fe80::5efe:c0a8:303/64 Scope:Link UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1364 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:1 dropped:0 overruns:0 carrier:1 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:252 (252.0 B) I configure bird with a static device route through that interface: ... protocol device { scan time 10; # Scan interfaces every 10 seconds } protocol direct testD { interface "*"; } protocol static testS{ route 10.20.0.0/24 via "vti0"; } ... This route is never set unless I configure an IP address on the VTI interface. If I repeat the same steps and use Quagga instead of Bird then route is set. Am I missing something in the configuration? Best regards Alexander Velkov

BGP attribute ext-next-hop
by Arvin Gan 18 Apr '18

18 Apr '18

Hi all, The version of my bird is 2.0.0, I found the source code of bird can support the attribute ext_next_hop for BGP, and this attribute is also parsed in cf-parse.y, but cannot found in user's guide document. Does anyone know what configuration is coherent with the attribute ext_next_hop? Is the attribute ext_next_hop fully supported in version 2.0.0 ? Thanks Arvin

local address as next-hop
by Alexander Demenshin 15 Apr '18

15 Apr '18

Hi, When next-hop specified as a local address, bird 2 produces a warning like: 2018-04-15 18:34:31.136 <WARN> Next hop address 192.168.100.100 is a local address of iface routers and the route itself is installed as "unreachable". Is there any reason for this? It is completely legal under linux, according to iproute2 documentation: via ADDRESS the address of the nexthop router. Actually, the sense of this field depends on the route type. For normal unicast routes it is either the true next hop router or, if it is a direct route installed in BSD compatibility mode, it can be a local address of the interface. For NAT routes it is the first address of the block of translated IP destinations. -- With best regards, Alexander.

bird 2.0.2 does not propagate krt_metric set in static routes when exporting to kernel (and couple other small issues in static protocol)
by Alexander Demenshin 15 Apr '18

15 Apr '18

Hi, Looks like setting of krt_metric in bird 2.0.2 does not work like in bird 1.6. Construction like: protocol static static4 { route 0.0.0.0/0 via 1.1.1.1 { krt_metric = 10000; }; } is accepted, I see the route exported to the kernel, but with default bird metric 32. Yes, I know that bird can find the best route and install only that one, but I prefer to keep several static routes installed with different metrics, when bird is used only to keep them alive. Another issue, when setting via scope using "%" notation, like: route 1.2.3.0/24 via 1.1.1.1 % ifname onlink on; if "ifname" contains characters like "-" or ".", it will be rejected (syntax error), while such names are perfectly legal (at least in linux). May be it makes sense to allow quoted (TEXT instead of SYM) interface name for such cases (I tried to extend grammar and it works perfectly - fix is trivial so there is no patch attached). Small annoyance, though not an issue - "route" only accepts CIDR notation, though it would be nice to omit "/32" for single IPs, as it looks more "natural". Finally - looks like bird 2 docs is a bit incorrect - static route options must be followed by ';' as a terminator (according to grammar), while documentation lists them without, which produces "syntax error" without any details. BTW, "onlink" is not documented at all, though I was really happy to find it :) PS: As this is my first experience with bird v2 - many thanks - it is much better :) -- With best regards, Alexander.

manipulating the best path, eBGP, MED?
by Thomas＠PhaseHosting 14 Apr '18

14 Apr '18

Supp, I implemented bird in our Private cloud running proxmox to distribute our public address with eBGP to our serverhost. Through iBGP and a ucarp interface i have a HA gateway, the problem is that our host receives the routes but there are multiple entry points to our subnet ( the proxmox hosts). This makes that a diffrent in & out route doenst work. through following link: https://supportforums.cisco.com/document/126691/understanding-bgp-best-path… I learned that my hosts selects its route based on age ( the bird with the first connection is chosen). Can i send a multi-exit discriminator with my eBGP connection to my host? I googled but could find 2 answers that did't change anything: # your default gateway IP below here protocol bgp eBGP { import none; export where proto = "static_packet"; local as 65000; neighbor 10.80.x.x as 65530; password "SECRET"; #med metric 10; #default bgp_med 10; } (offcourse i tried both without # and waited till export) Or is there an other way to make sure that our host routes always to the first server and so on. -- Thomas Valgaeren thomas(a)phasehosting.io +32477915307
