OSPF Configuration Issue

Sguillen34

Level 1

I'm trying to setup OSPF routing over Frame Relay and I'm having a problem getting into config-router mode on 2610 router. I'm at global config and I enter

R3#router ospf 1 and it accepts it, but stays in config so I'm not able to enter in any network statements.


R3(config)#router ospf 1
R3(config)#

Clearly the router is capable of running OSPF. I really appreciate any feedback or insight into the problem!

Thanks

Here's my config on the router:


version 12.3
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption

Hi,

I rememeber faching this issue when there is no IP interface in UP/UP state. Try configuring a loopback interface with some address and then try "router ospf". Else try bringing the frame-relay intf up and then try "router ospf"

HTH,

Hi,

I dont see the mode changing to (config-router)

R3(config)#router ospf 1
R3(config)#

Could you check in show process CPU if the ospf process is running ?

I checked the processes and I don't see OSPF running. My other routers don't have any loopback interfaces set, but they can still get into router config mode without an issue.

Upgrade IOS.

I wish I could try, but I have the latest IOS.

I've thought that maybe it's related to the physical interface or the fact that I'm using a point-to-point interface.

So I physically removed and reseated the serial interface. I've also tried using another physical interface and finally I've tried setting up frame relay over just the physical interface without point-to-point or multipoint and I still can't get into router config mode. I tested it with the other protocols and it works.

Is it possible that there could be a physical defect?

Thanks so much for your help on this issue. I found the solution! It was the IOS version all along,but I didn't think it was since it displayed OSPF as an option.

I had the REMOTE ACCESS SERVER c2600-c-mz.123-26.bin version which doesn't support it so I had to get the Enterprise Basic version that supports it. Man that was frustrating!

Thanks again!
