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>

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.
