<div dir="ltr">Hi everyone<br><br>I apologise in advance, english is not my native language...<br><br>For study purpose, I'm trying to setup OSPFv2 between Bird 1.6.6 and a Cisco router.<br><br>It
seems there is a problem with the auth-type code send by Bird in the
ospf hello packets. This problem prevent the devices to become
neighbours.<br><br>Here is the configuration of the Cisco router :<br><br>router ospf 1<br> no capability lls<br> network 192.168.42.0 0.0.0.255 area 0.0.0.0<br><br>interface Vlan10<br> description Management<br> ip address dhcp<br> ip ospf authentication<br> ip ospf authentication-key azerty<br> ip ospf dead-interval 6<br> ip ospf hello-interval 2<br><br>And the configuration of Bird :<br><br>router id 1.1.1.1;<br><br>protocol device {<br>}<br><br>protocol kernel {<br> metric 64; <br> import all;<br> export all; <br>}<br><br>protocol ospf test {<br> instance id 42;<br> area 0.0.0.0 {<br> interface "eth*" {<br> hello 2;<br> dead count 3;<br> authentication simple;<br> password "azerty";<br> };<br> };<br> export all;<br>}<br><br>If I launch the debug command on the Cisco, I see this : <br><br>Mar 23 18:09:59: OSPF-1 PAK : Vl10: OUT: 192.168.42.43-><a href="http://224.0.0.5" target="_blank">224.0.0.5</a>: ver:2 type:1 len:44 rid:192.168.42.43 area:0.0.0.0 chksum:2720 auth:1<br>Mar 23 18:09:59: OSPF-1 PAK : Vl10: IN: 192.168.42.73-><a href="http://224.0.0.5" target="_blank">224.0.0.5</a>: ver:2 type:1 len:52 rid:1.1.1.1 area:0.0.0.0 chksum:F0CE auth:10753<br><br>Bird send the field auth-type with the value 10753. <br><br>Tcpdump show the same value : <br><br>17:13:38.012494 IP (tos 0xc0, ttl 1, id 21850, offset 0, flags [none], proto OSPF (89), length 64)<br> 192.168.42.43 > <a href="http://224.0.0.5" target="_blank">224.0.0.5</a>: OSPFv2, Hello, length 44<br> Router-ID 192.168.42.43, Backbone Area, Authentication Type: simple (1)<br> Simple text password: azerty<br><br>17:13:38.012792 IP (tos 0xc0, ttl 1, id 7301, offset 0, flags [none], proto OSPF (89), length 72)<br> 192.168.42.73 > <a href="http://224.0.0.5" target="_blank">224.0.0.5</a>: OSPFv2, Hello, length 52<br> Router-ID 1.1.1.1, Backbone Area, Authentication Type: unknown (10753)<br><br><br>Can
