Hi, I have this bird.conf : ############## router id 213.xx.xx.xx; protocol kernel { persist; scan time 20; import all; export all; } protocol static { route 0.0.0.0/0 via 213.xx.xx.yy; } protocol ospf MyOSPF { tick 2; rfc1583compat yes; export where source = RTS_STATIC; area 10.32.0.0 { stub no; networks { 77.xx.xx.4/30; 77.xx.xx.8/30; }; interface "vlan10" { cost 10; priority 1; authentication none; type nonbroadcast; strict nonbroadcast yes; neighbors { 77.xx.xx.6; }; poll 10; retransmit 5; transmit delay 1; hello 10; dead 40; wait 40; }; interface "vlan11" { cost 100; priority 1; authentication none; type nonbroadcast; strict nonbroadcast yes; neighbors { 77.xx.xx.10; }; poll 10; retransmit 5; transmit delay 1; hello 10; dead 40; wait 40; }; }; area 10.0.8.0 { stub no; networks { 77.xx.xx.0/30; }; interface "vlan13" { cost 1; priority 1; authentication none; type nonbroadcast; strict nonbroadcast yes; neighbors { 77.xx.xx.2; }; poll 10; retransmit 5; transmit delay 1; hello 10; dead 40; wait 40; }; }; }; ############## This configuration makes immediate crash of bird, with this syslog message: Nov 4 23:34:39 router user.info kernel: bird[5236]: segfault at 34 ip 0805f8d6 sp bfb262f0 error 4 Nov 4 23:34:39 router user.info kernel: in bird[8048000+3c000] If I remove part with 'area 10.0.8.0', bird runs without problem. Thanks for suggestion. Jirasek
