Hello, I'm using bird mostly for OSPF suppor. On one of my OSPF-connected sites (running bird 1.6.8 on a FreeBSD 13.2-RELEASE-p12) I needed to put my bcast area0 interface into non-default FIB (the purpose is to make 192.168.31.0/24 use a default gateway radically other that the main FIB is using): ===Cut=== igb0: flags=8863<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=4e527bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,WOL_MAGIC,VLAN_HWFILTER,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6,NOMAP> ether 9c:8e:99:31:b1:ba inet 192.168.31.30 netmask 0xffffff00 broadcast 192.168.31.255 inet 192.168.31.2 netmask 0xffffff00 broadcast 192.168.31.255 inet 192.168.31.52 netmask 0xffffff00 broadcast 192.168.31.255 fib: 1 media: Ethernet autoselect (1000baseT <full-duplex>) status: active nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> ===Cut=== Almost everything continued to work fine, except two things: 1) now bird complains about a socket on this interface: calypso bird[79957]: ospfv4: Socket error on igb0: Network is unreachable 2) now the igb0-neighbors are stuck in ExtStart phase (this is obviously related to the previous issue): Router ID Pri State DTime Interface Router IP 192.168.31.1 1 ExStart/DR 00:36 igb0 192.168.31.1 How can I fix this, probably without massive configuration changes, like putting 192.168.31.0/24 on a separate vlan and assigning this vlan to a FIB 1 ? Thanks.
