Dear Quagga-List

interface eth1 looks ok in  zebra:
Router# show interface eth1
Interface eth1 is up, line protocol detection is disabled
  index 3 metric 1 mtu 1500
  flags: <UP,BROADCAST,RUNNING,MULTICAST>
  HWaddr: 00:16:3e:3c:32:ad
  inet 10.10.10.99/27 broadcast 10.10.10.127
  inet 10.10.99.1/29 broadcast 10.10.99.7 eth1:1
  inet6 fe80::216:3eff:fe3c:32ad/64
    6104318 input packets (0 multicast), 398008284 bytes, 0 dropped
    0 input errors, 0 length, 0 overrun, 0 CRC, 0 frame
    0 fifo, 0 missed
    1794 output packets, 152356 bytes, 0 dropped
    0 output errors, 0 aborted, 0 carrier, 0 fifo, 0 heartbeat
    0 window, 0 collisions
Router#

Two hosts, 99 and 103 get different results for the same configuration:

bwhavior on host 103:

ospfd# show ip ospf interface

eth0 is up

  ifindex 2, MTU 1500 bytes, BW 0 Kbit <UP,BROADCAST,RUNNING,MULTICAST>

  OSPF not enabled on this interface

eth1 is up

  ifindex 3, MTU 1500 bytes, BW 0 Kbit <UP,BROADCAST,RUNNING,MULTICAST>

  Internet Address 10.10.10.103/27, Broadcast 10.10.10.127, Area 0.0.0.0

  MTU mismatch detection:enabled

  Router ID 10.10.10.103, Network Type BROADCAST, Cost: 10

  Transmit Delay is 1 sec, State Backup, Priority 1

  Designated Router (ID) 10.10.10.123, Interface Address 10.10.10.123

  Backup Designated Router (ID) 10.10.10.103, Interface Address 10.10.10.103

  Multicast group memberships: OSPFAllRouters OSPFDesignatedRouters

  Timer intervals configured, Hello 10s, Dead 40s, Wait 40s, Retransmit 5

    Hello due in 2.039s

  Neighbor Count is 1, Adjacent neighbor count is 1

gre0 is down

  ifindex 4, MTU 1476 bytes, BW 0 Kbit <NOARP>

  OSPF not enabled on this interface

lo is up

  ifindex 1, MTU 16436 bytes, BW 0 Kbit <UP,LOOPBACK,RUNNING>

  OSPF not enabled on this interface


Behavior on host 99:

ospfd# show ip ospf interface

eth1 is down

  ifindex 0, MTU 0 bytes, BW 0 Kbit <>

  OSPF not enabled on this interface
ospfd#

Obviously, Hello messages from 103, none from 99

Any suggestions?
