My distro (Fedora 38) updated frr from 8.5.1 to 8.5.2 yesterday and upon restart of frr after that update, OSFP routing stopped working. It was working find prior to that. When I use vtysh to show the ospf route database: # show ip ospf database route % OSPF is not enabled in vrf default and indeed, the running config shows no OSPF configuration: # show running-config Building configuration... Current configuration: ! frr version 8.5.2 frr defaults traditional hostname pc.example.com no ipv6 forwarding no service integrated-vtysh-config ! end But my configuration files do configure ospf: ----- /etc/frr/daemons ----- bgpd=no ospfd=yes ospf6d=no ripd=no ripngd=no isisd=no pimd=no pim6d=no nhrpd=no eigrpd=no sharpd=no pbrd=no bfdd=no fabricd=no vrrpd=no pathd=no vtysh_enable=yes zebra_options=" -A 127.0.0.1 -s 90000000" bgpd_options=" -A 127.0.0.1" ospfd_options=" -A 127.0.0.1" ospf6d_options=" -A ::1" ripd_options=" -A 127.0.0.1" ripngd_options=" -A ::1" isisd_options=" -A 127.0.0.1" pimd_options=" -A 127.0.0.1" pim6d_options=" -A ::1" nhrpd_options=" -A 127.0.0.1" eigrpd_options=" -A 127.0.0.1" sharpd_options=" -A 127.0.0.1" pbrd_options=" -A 127.0.0.1" staticd_options="-A 127.0.0.1" bfdd_options=" -A 127.0.0.1" fabricd_options="-A 127.0.0.1" vrrpd_options=" -A 127.0.0.1" pathd_options=" -A 127.0.0.1" ----- /etc/frr/frr.conf ----- hostname pc.interlinx.bc.ca ----- /etc/frr/ospfd.conf ----- hostname pc password ospf4me enable password ospf4me ! router ospf ospf router-id 10.75.22.1 network 10.75.22.0/24 area 0 ! network 192.168.122.0/24 area 1 ! network 192.168.0.0/24 area 1 ! redistribute connected ----- /etc/frr/staticd.conf ----- ----- /etc/frr/vtysh.conf ----- no service integrated-vtysh-config ----- /etc/frr/zebra.conf ----- hostname pc password zebra enable password zebra log stdout interface pc_bridge link-detect interface virbr0 no link-detect This is the very same config that worked with 8.5.1 and is working on other machines in the network (albeit with earlier versions of frr as they are "EL8" systems which don't update as quickly as Fedora). Is there something about this configuration that is not compatible with 8.5.2? Cheers, b.
