Ospf state INIT and not FULL

Hello i have a problem beacuse the ospf protocol can´t pass to FULL state, this said that is INIT, the configuration in both interface are:

end

Only on R1 i see the state of INIT

R_1#sh ip ospf neighbor R_2#sh ip ospf neighbor

Re: Ospf state INIT and not FULL

Hi,

there seems to be something wrong with your interface on R2. It has NO inputs whatsoever.

  Last input 6d21h, output 00:00:00, output hang never

  0 packets input, 0 bytes, 0 no buffer

  109525 packets output, 9386764 bytes, 0 underruns

Your show ip ospf neighbor output just underlines this fact.

The INIT state on R1 means, that R1 has received a hello packet from R2, but R1 can't see its own ID included in R2's hello packet. When a router receives a hello packet from a neighbor, it should list the sender's router ID in its hello packet as an acknowledgment that it received a valid hello packet. If it doesn't, OSPF remains stuck in INIT.

So, your output clearly says that R1 is sending hello packets and receiving some, but not with its own ID in it. R2 is sending hello packets to R1, but isn't receiving any.

The problem seems to be in underlying technology - link itself or the interface - have you tried to ping that interface? It shouldn't work.

I am sorry, but I don't know how to fix this, I just saw that you want make OSPF work but the problem seems to be somewhere else, not in OSPF itself or anything related to it.

Best regards,

Jan

Ospf state INIT and not FULL

Thanks....

ok, Ready...

when i make a ping between R1 and R2 don´t answer...

I do reset of interface because this have a problem with the Overload traffic and this bloked and dont work

Re: Ospf state INIT and not FULL

This does sound like a connectivity issue between the two routers.

Can you post the output of 'show ip ospf int mu11' for me?

The link between these two routers, is this something you control, or is it provider equipment?

      

I also see 'mpls ip' is on each one, but labels are created from IGP.

Would it hurt anything to take off the 'mpls' config and try a test ping?

Ospf state INIT and not FULL

Hi...

Here is the command...

Multilink11 is up, line protocol is up

  Internet Address 172.16.49.17/30, Area 0

  Process ID 1, Router ID 150.220.250.1, Network Type POINT_TO_POINT, Cost: 12500

  Topology-MTID    Cost    Disabled    Shutdown      Topology Name

        0           12500     no          no            Base

  Transmit Delay is 1 sec, State POINT_TO_POINT

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

    oob-resync timeout 40

    Hello due in 00:00:08

  Supports Link-local Signaling (LLS)

  Cisco NSF helper support enabled

  IETF NSF helper support enabled

  Index 16/16, flood queue length 0

  Next 0x0(0)/0x0(0)

  Last flood scan length is 1, maximum is 39

  Last flood scan time is 0 msec, maximum is 8 msec

  Neighbor Count is 1, Adjacent neighbor count is 1

    Adjacent with neighbor 150.220.250.180

  Suppress hello for 0 neighbor(s

Yes i have the control, the interface is saturated and bloeked,which although the status and protocol are up.

Apparently is a BUG so I'll have to upgrade the IOS
