Thank you.

There is a beta FW that resolved some OSPF issues for the 6024.  You might want to contact support and ask them about your problem.  If it is determined that the beta FW will help with this issue they can provide you with this FW.

A colleague of mine pointed out that the Cisco switch may have been misconfigured in this case and the problem is not on the 6024 side.
 
He refers you to this document at Cisco site (there are other places on Cisco site with similar information):
 
Specifically you need to re-distribute the ODR routes into OSPF.

I took a look at this, but I don't see where this will help.  I am running OSPF throughout my organization.  I think this pertains to redistributing routes from another routing process like EIGRP or BGP.

March 9th, 2006 04:00

That's odd. I don't see the same issue. My network is somewhat different (I've cleverly avoided having anything >1 hop from the 6024 [i.e. it's a tiny, local network], although I've had some pretty convoluted setups in the past), and I'm running the somewhat ugly MD5 auth. But the routes come through, eventually. I assume your neighbor states show full on both sides?

I'd like to see the release notes on that beta firmware. My little tag thingie is apparently underneath the switch, and I really don't care to unshelve it right at the moment. I can't seem to even ask a question (of Support) without it. CN, would you mind posting those?

Thanks.

Since this code is still in beta phase there is no official release notes for it.  I can describe briefly what it fixes though.  The bug is in the OSPF area and occurs only on a large network, especially one where the routers are distributed in a wide area.  Because of certain timing issues the OSPF database does not always properly update and you may get "OSPF LSA checksum error" between two routers which prevent correct propagation of new routes.  The telling sign is that you get an OSPF error message in your log indicating update errors or checksum errors.  In a small network or mostly local network you never see this timing problem.

I'm not certain this fix will address the original question (from smull14) so I suggest contacting support who can walk through the problem and make sure the FW will address the problem.

Thanks.  Heh.  I was hoping for OSPF MD5 and SNTP fixes (both are mainly annoying, the former in particular).  I'll be curious to see what Sean's issue is.

Well, I did open a ticket with support, so I will wait to hear back from them.  Like Peter had mentioned, it looks like the 6024 is just seeing the connected subnets from the Cisco router and none of the remote subnets.  I logged into the Cisco Internet Router on the same subnet as the 6024 and turned on OSPF Routing.  It sees all of the routes from the WAN router just fine.  I've tried chaning a number of OSPF settings on the router and switch and nothing seems to make a difference.  Anyway, I will let you know if support is able to help.

Sean,

One of my colleague ran a quick test and he believes that the 6024 operates correctly.  Here is his setup:

                Fe0/0                     g1

Cisco2800----------------------------------PC6024

|  fe0/1

|

|

| ge0/0

Cisco3825

In his test the PC6024 is receiving all the routes from the 2800 and the subnet learn from 3825.
 
Perhaps your network has some unique characteristics that's different from this experiment?  Also can you tell us what version of FW you are running?
 
Here is the configuration that my colleague setup and tested:

Also, just to add - This morning I created an EIGRP process on the Cisco 3825 and redistributed this into the OSPF process. The PC6024 correctly injected the External OSPF routes into its table.

Thanks

Hmm.  That is identical to my configuration on both the routers and the switch.  I will reboot them all this evening to see if something is hung somewhere.  I don't know if it makes a difference, but I haven't rebooted the switch since I first installed it.  Do you think it would require a reboot after adding the OSPF configuration commands?  Thanks.

Hi Sean


You should not have to reboot the switch for the OSPF commands to work correctly, could you post what Hardware revision your switch is and what firmware you are running?


Thanks

Well, you were right.  The reboot didn't help.  I did find some new information however.  When I run the command 'show ip ospf database' on the 6024, I can see all of the routes in the OSPF database.  They just aren't being transferred to the routing table.

Hi Sean

If possible can you post your full cisco configs, obviously remove all passwords etc. Also can you tell me what model cisco routers your using and IOS version, as well as PC6024 HW version.

thanks
