OSPF help

okay here is is R2 and R1 connected by ethernet.
you can ping to both sides but there is no neighbor relationship? why?
like they don't even see each other but you have ip layer access?
I have no clue why I cannot get ospf to work on these routers to
create routing tables?

APA

Can you post your configs?

Looking at the debug... off the top of my head... I'd say that your network statements are incorrect...

It looks as if they can't see each others OSPF messages......as no OSPF states have changed, although I don't know how much debugging you've enabled...

- Make sure network statements are correct (IP subnet and area)
- Make sure network types are the same on interfaces (ptp or network)

ConstantlyLearning

And the pings were between the F0/0 interfaces of R1 and R2 yes?

keenon

you need to post 3 things.

1. show cdp n from each router
2. router interface configs from each router
3. routing process config from each router

Monkerz

You can ping between R1 and R2 because they both have a "connected" route in the routing table to the network they are attached to (Fa0/0 to Fa0/0).

From the debuging data, it appears that your routers are attempting to elect themselves as both the DR and BDR. As stated earlier, the routers are not seeing one another so it is probably a fat fingered network statement. (I do this alot,

)

Forsaken_GA

assuming they're both connected to each other via fa0/0, the network statement is probably not the issue. They're both running OSPF on that interface, and the network statement doesn't set the actual subnets to form an adjacency over, just which interfaces OSPF will participate on.

That looks like either MTU problems, or something munging multicast, but I agree, full configs on both routers would be nice, along with a mockup of the topology (ie, are they directly connected to each others fa0/0, or is there a switch in the mix?)

amb1s1

Yes, we need to configs to help you out.

Mee too I think it is fat fingered network statement.

Is not an MTU Problem because you would see an message on the debug ip ospf adj about having the wrong MTU. You will get something like this:

OSPF: Nbr 1.1.1.1 has smaller interface MTU
or
OSPF: Nbr 2.2.2.2 as larger interface MTU

But again, we need the config to see the entire picture.

r8 ethernet to r2 ethernet to r1 frc to r3 bb1

r1 frc to r4 bb2

issue lies where r1 and r3 and r4 have ospf routing tables that can talk
to each other fine. but from r1 fastethernet on subnet 192.168.1.x /30.
nothing. it is like r2 and r8 are in their own world and there is no merging
of ospf lsa?

Are you doing this lab on GNS3? You config look good. Can you do debug ip ospf event

amb1s1

Found it, the problem is that to be able to established a neighbor with a neighbors the interfaces got to be in the same subnet. YOu have router2 interface Fa0/0 on /30 subnet

R2
---
interface FastEthernet0/0
ip address 192.168.1.2 255.255.255.252
speed auto
full-duplex

and router 1 on a /24 subnet

interface FastEthernet0/0
ip address 192.168.1.1 255.255.255.0
speed auto
full-duplex

To solve this problem you either move R1 to a /30 subnet or r2 to /24 subnet.

Forsaken_GA

your netmasks are mismatched between r1 and r2 on the fa0/0 interfaces. r2 has it configured as a /30, r1 has it configured as a /24

edit: damn, little too slow

DPG

Your IP subnets and network statements are mismatched.

[B]R1[/B]
interface FastEthernet0/0
ip address 192.168.1.1 255.255.255.[B]0[/B]

network 192.168.1.0 0.0.0.[B]255[/B] area 0


[B]R2[/B]
interface FastEthernet0/0
ip address 192.168.1.2 255.255.255.[B]252[/B]

network 192.168.1.0 0.0.0.[B]3[/B] area 0

They interfaces need to have the subnet mask and the network statements need to have the same wildcard mask in order for the adjacency to form.

Forsaken_GA

You're also going to want to adjust the wildcard masks for the network statements to be consistent, particularly if your goal is for these links to be a /30. ie, you may not necessarily want the router currently configured as a /24 to match on a 24 bit mask if your goal is to only advertise that /30, if you leave it that way, and you configured anything else in the 192.168.1.0/24 range, say for another point to point link, then that subnet would automatically get injected into ospf.

Personally, I prefer to explicitly match the interface in the network statement if I'm using it to configure OSPF (I usually enable ospf at the interface level).

of course, I also define passive-interface by default as well. Then I explicitly no passive-interface the interfaces I do want running OSPF, so I make it really hard to screw up and accidentally add an interface to the routing protocol.

OMG..you are right I just didnt see that aahahha wow I should have gone thru the basics step by step I just kep relying on the ping since it did work
but I completely see what you see fixing this tomorrow will let you know. I was look at timers and they looked good and I was like what the heck is it hahah thanks guys I willl look and fix it tomorrow morning and report back my success. thanks so much for your keen site. yeah I can sleep now.
what a cool exercise in troubleshooting wow! I should have looked at each factor. great exercise....see you tomorrow...

devil's in the details. I cannot explain how many times I've run into problems that at first blush, everything seemed correct, and was going off on all kinds of tangents trying to figure it out, and it turned out to be something stupid like a typo.

When in doubt, always bet on stupid.

APA

See what happens when you post configs up....

Definitely explains why they weren't seeing each other.... perfect example of always thoroughly checking your config before applying it.

oh yeah you guys are awesome. man I feel so dumb hahaha
yeah works great!!thank you for being my eyeballs!
