Route table max up to 32K
by Bryan Duff 18 Nov '13

18 Nov '13

Any reason why the max route table is limited to 256 and not the Linux limit of 32767? Also any thoughts of adding dbus support or something similar for direct command injection (instead of rewriting the config and HUP'ing)? Thanks. -Bryan

simple filters question
by John Jensen 08 Nov '13

08 Nov '13

Hi, We're about to migrate our exchange to a /23 and we're likely going to do it over time. I have a simple filter in place to check and make sure that the NEXT_HOP is within our exchange's subnet. Originally it looked like this: function check_ixp_next_hop(ip nexthop) prefix ixpnet; { ixpnet = x.x.x.x/24; if ! (nexthop ~ ixpnet) then return false; return true; } And then within the inbound filter for each peer's ASN: if ! (check_ixp_next_hop(bgp_next_hop)) then reject; Since we're going to be caring about two distinct prefixes while we perform the migration, I changed the filter to look like this: function check_ixp_next_hop(ip nexthop) prefix set ixpnet; { ixpnet = [ x.x.x.x/24, y.y.y.y/23 ]; if ! (nexthop ~ ixpnet) then return false; return true; } However I'm getting the following errors in the log: 07-11-2013 12:33:00 <ERR> filters, line 61: ~ applied on unknown type pair 07-11-2013 12:33:00 <ERR> filters, line 61: ~ applied on unknown type pair 07-11-2013 12:33:04 <ERR> filters, line 61: ~ applied on unknown type pair Am I missing something? Thanks, -JJ

How bird configure multiple instances on ospf?
by 曾小小 06 Nov '13

06 Nov '13

I am now in use BIRD in the ospf routing protocol, such as cisco router I want to use multiple processes on the ospf. This how to achieve it ? Such as cisco router multi-process examples: r1 (config) # router ospf 100 r1 (config-router) # network 192.168.3.0 0.0.0.255 area 0 r1 (config-router) # network 10.0.5.0 0.0.0.255 area 0 r1 (config-router) # exit r1 (config) # router ospf 101 r1 (config-router) # network 10.0.7.0 0.0.0.255 area 1 My configuration is as follows , but I do not know if this configuration is not multi-process approach. filter export_OSPF { if (source = RTS_STATIC && net = 0.0.0.0 / 0) then { print "net accepted:", net; ospf_metric2 = 20; accept; } reject; } # # protocol ospf ospf_1 { table tab_ospf_1; router id x.x.x.x debug all; export filter export_OSPF; import all; preference 200; area 0.0.0.0 { interface "gre0" { hello 10; retransmit 5; cost 10; transmit delay 1; dead count 4; wait 40; type pointopoint; # type pointomultipoint; # type broadcast; priority 0; authentication cryptographic; password "abc"; } ; } ; } # # protocol ospf ospf_2 { table tab_ospf_2; router id x.x.x.x; # Debug all; export filter export_OSPF; import all; preference 200; area 0.0.0.0 { interface "gre1" { hello 10; retransmit 5; cost 10; transmit delay 1; dead count 4; wait 40; type pointopoint; # type broadcast; # type pointomultipoint; priority 0; authentication cryptographic; password "abc"; } ; } ; } Thank you..

Bird within netns (no OS routing table injection with BGP)
by Julien VAUBOURG 04 Nov '13

04 Nov '13

Hi all, I'm trying to use bird within netns with something like "ip netns exec foo bird". I can see received routes in "show route" but the injection in the OS routing table is not done. Strangely, static routes are correctly injected. With BGP routes I have no particulary debug messages, except "Netlink: Invalid argument" with bird6. Using Quagga, routes are correctly injected inside netns. Any idea about that problem? * Bird 1.3.7-1 * GNU/Linux (Debian Wheezy) Regards, ju.

FreeBSD, OSPF, and multicast
by Claude Marinier 01 Nov '13

01 Nov '13

Hi, I am building a WAN emulator using a FreeBSD server with DummyNet for WAN effects and BIRD for OSPF. At first, no multicast packets left the server; then I added a default route and they left by that interface only. How can I configure the server so BIRD sends HELLO packets out all the interfaces. Thank you. Details: FreeBSD WAMemu 9.2-RELEASE FreeBSD 9.2-RELEASE #0 r255898: Thu Sep 26 22:50:31 UTC 2013 root@bake.isc.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 bird-1.3.11 P.S. I got it working by avoiding multicast with 'type nonbroadcast' and 'neighbors'. -- Claude Marinier

Where did the BGP examples go
by Bill Reid 31 Oct '13

I was looking for the BGP examples on the Bird web site. I thought I previously found them via the wiki link but that link does not point to the wiki page but to Labs Redmine. Thanks, Bill

Bird not installing OSPF learned routes into routing tables
by Lex van Roon 28 Oct '13

28 Oct '13

Hi All, Recently I've migrated one of my Debian Squeeze / bird 1.3.8 route reflectors to FreeBSD 10-BETA1 / bird 1.3.11. This reflector has multiple gre-based links, over which I advertise loopback addresses using OSPF, which are in turn used to establish iBGP sessions. The problem is that it seems that Bird is not installing OSPF learned routes into the routing table, and I'm not quite sure how to proceed with this. Please see the output below: I've got two OSPF neighbors, which successfully initialize: bird> show ospf neighbors as65342_igp: Router ID Pri State DTime Interface Router IP 10.42.0.1 1 full/ptp 00:15 gre0 10.42.4.1 10.42.0.3 1 full/ptp 00:10 gre1 10.42.8.2 I can see all routes that are being advertized within the OSPF network: bird> show ospf state area 0.0.0.0 router 10.42.0.1 distance 10 router 10.42.0.3 metric 10 router 10.42.0.4 metric 10 router 10.42.0.2 metric 10 stubnet 10.42.0.1/32 metric 0 stubnet 10.42.0.123/32 metric 0 stubnet 10.42.4.8/30 metric 10 stubnet 10.42.4.12/30 metric 10 stubnet 10.42.4.0/30 metric 10 router 10.42.0.2 distance 0 router 10.42.0.1 metric 10 router 10.42.0.3 metric 10 stubnet 10.42.4.0/30 metric 10 stubnet 10.42.0.2/32 metric 0 stubnet 10.42.8.0/30 metric 10 router 10.42.0.3 distance 10 router 10.42.0.2 metric 1000 router 10.42.0.1 metric 1000 stubnet 10.42.0.3/32 metric 1 stubnet 10.42.8.0/30 metric 1000 stubnet 10.42.4.8/30 metric 1000 router 10.42.0.4 distance 20 router 10.42.0.1 metric 10 stubnet 10.42.0.4/32 metric 0 stubnet 10.42.4.12/30 metric 10 However, I'd expect the stubnet routes to be available to the routing tables that are used within Bird, and it seems that they are not exported: bird> show route protocol as65342_igp 10.42.0.2/32 dev disc0 [as65342_igp 15:39] * I (150/0) [10.42.0.2] bird> show route table routers 10.42.0.2/32 dev disc0 [as65342_igp 15:39] * I (150/0) [10.42.0.2] The relevant configuration for this is below. The exact same configuration worked with Linux: function accept_loopback_prefixes() { if net ~ [ 10.42.0.0/24{32,32} ] then accept; } protocol ospf as65342_igp { table routers; rfc1583compat no; ecmp yes; import filter { accept_loopback_prefixes(); reject; }; export filter { accept_loopback_prefixes(); reject; }; area 0.0.0.0 { interface "disc0" { stub on; }; interface "gre0", "gre1" { wait 3; hello 5; dead count 3; retransmit 1; check link on; }; }; } When I enable Bird debugging (full OSPF log output available below), I can see all routes succesfully exchanging LSA's and starting the routing table calculation + synchronisation, however the calculated routes are never installed into the 'routers' table, nor do I see Bird make any attempts and/or throw errors while doing this. Do you know how I could proceed in getting this to work?

Dear list, can you explain why the following route (0.0.0.0/0) is selected to go via as403, as as4057 clearly displays the shortest path here? As you can see I have used bgp_path.prepend() 3x on as403 for its own ASN. Thanks, Amadeus bird> show route for 0.0.0.0/0 table ffc all 0.0.0.0/0 via 169.254.40.3 on ffc403 [as403 14:38] * (150) [AS403i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 403 403 403 403 BGP.next_hop: 169.254.40.3 BGP.local_pref: 100 via 169.254.40.64 on ffc4064 [as4064 14:32] (100) [AS4057i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 4064 40120 4057 BGP.next_hop: 169.254.40.64 BGP.local_pref: 100 via 169.254.40.57 on ffc4057 [as4057 Oct14] (100) [AS4057i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 4057 BGP.next_hop: 169.254.40.57 BGP.local_pref: 100

Hello How to learn from the BIRD routing table to output to the freebsd multiple routing tables. Similar to the linux environment bird table specified routing table can be output to the rt_table in iproute2. My freebsd system version is FreeBSD 10.0-BETA1, BIRD version BIRD 1.3.11. Since my freebsd system configured setfib, and on the pf.conf of rtable. I was able to learn from the BIRD to the ospf routing (the route saved in the specified table in the) output to the freebsd pf the rtable in it? How do I configure it? At the same time, how can I be in the table BIRD route output to setfib in it? How to configure it?
