This is definitely reproduceable here (RedHat 7.3, all security updates installed, zebra-0.92a-3.i386.rpm I rebuilt the RPM from RedHat 9 under 7.3 (rpm --rebuild zebra-0.93b-1.src.rpm) and installed it instead and this fixed all the problems. Now my routes get redistributed just fine. 7.3 has been unsupported for quite some time now. If you can reproduce the problem with a currently supported product, open a new bug. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.3 (X11; Linux i686; U;) Gecko/20020524 Description of problem: If an interface is configure in a "static" way (no dhcp/bootp) then zebra wont insert into the main routing table the routes ospfd has learned. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.netconfig -> choose an ip, a mask, eventually a ns-server and a gateway. 2. service network restart 3. Configure zebra something like that : /etc/zebra/zebra.conf : [root@router-rome /tmp]# cat /etc/zebra/zebra.conf ! ! Zebra configuration saved from vty ! 2002/06/06 12:37:29 ! hostname router-munich password admin log file /var/log/zebra/zebra.log log syslog ! interface lo ! interface eth0 ! interface eth1 ! etc .. one line for each interface... ! line vty ! 3. service zebra start 4. Configure ospfd : /etc/zebra/ospfd.conf : ! ! Zebra configuration saved from vty ! 2002/06/05 19:44:31 ! hostname router-munich password admin log file /var/log/ospfd.log log stdout log syslog ! ! ! interface lo ! interface eth0 ! interface eth1 ! router ospf ! the network are all ethX networks.. network 192.168.162.0/24 area 0.0.0.0 network 192.168.186.0/24 area 0.0.0.0 ! line vty ! 5. service ospfd start 6. Assume you have another ospfd on one of your networks to share some routes with this router. 7. wait 30s. Actual Results: [root@router-munich ~]# telnet localhost ospfd Trying 127.0.0.1...

All ospfd routes are *not* inactive.

If I comment/del theese lines : 229 : # Add a route for the subnet. Replace any existing route. 230 : if [ "${ISALIAS}" = no ]; then 231 : ip route replace ${NETWORK}/${PREFIX} ${SRC} dev ${REALDEVICE} 232 : fi then zebra will work with absolutly no problem... I think that redhat7.2 concerned too but not redhat7.1.
