Hi !
I have a small network running 1 cisco and 2 zebra OSPF/BGP4 speakers.
Upgrade from zebra 0.89a to 0.90 went smoothly on my FreeBSD 4.2-STABLE
main server with a fxp0 interface.
I installed zebra 0.90 additionally on my laptop, which is also
FreeBSD 4.2-STABLE. This is a new installation.
There I experience major OSPF problems.
BGP4 runs fine, but OSPF simply doesnīt work.
As Ethernet interface I use a Xircom 10/100 Realport 16 Bit
card with modem. The major problem seems to be, that zebra
doesnīt find the xe0 interface...
Ccīd to the FreeBSD-mobile and Xircom mailinglist since zebra
runs on a FreeBSD-STABLE machine with a normal interface card
without trouble.
+---------------------------------------------------------------
"show ip ospf inter shows" results in:
aklemm-ospfd# sh ip ospf inter
lo0 is down, line protocol is down
OSPF not enabled on this interface
ppp0 is down, line protocol is down
OSPF not enabled on this interface
vmnet1 is down, line protocol is down
OSPF not enabled on this interface
xe0 is down, line protocol is down
^^^^^^^^^^^ <------------------------------------ !!!
OSPF not enabled on this interface
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ <----------- !!!!!!!!!!!!!!!

"show ip ospf" shows:

Same settings as on FreeBSD server ... this should do anything bad.

When using ethereal as sniffer on my freebsd server (all systems
are located on a Cisco 2516, which has a 14-port hub integrated)
I donīt see any OSPF packet transmitted from my laptop ...
When enabling all OSPF debugging on my laptop I donīt see any arriving
OSPF interface. If I bring the xe0 interface into up/down/up status
I see no additional debug output, no OSPF actually starting.
It looks like zebra OSPF totally ignores my interface.
The output of "sh ip ospf inter" and "sh ip ospf" (see above)
seconds that ...
Here some debugging output I collected after turning on all debugging
and bringing the interface up down several times:
