Working on IE II lab 1

Posted by Peter Kurdziel on November 2, 2008

I drew out my topology map with the routing protocols and my layer 2 map. I also wrote out my task tracker.

Loops = 2 but they are contained in a single routing protocol so I do not need to worry about them.

Spotting the issues:

Right off the bat I know there will be some sort of OSPF network type issue between R3-5 and a split an EIGRP split horizon issue on R2.

I started with Cat and moved on to FR. Then I skipped to RIP since it has the least amount of work to do. Then I moved on to EIGRP also since it does not have a lot of tasks.

I had company so I had to waste 6 hrs of my rack time.

I ran into a weird issue with EIGRP and got stuck.

I am getting a K-value mismatch & retry limit exceeded messages

strange…you don’t have a BW or timer mismatch do you?  your K values used seems to be the default on both ends at least.  i don’t think MTU has to match for EIGRP like it does with OSPF or i’d consider it as well.

Make sure that the interfaces are in the correct VLANs, do not put all interfaces of all routers in the same VLAN. If you are doing it in Frame-relay, you should ensure that there are no other frame mapping that ones desired.

Piotr,

Check that the MTUs match on both devices.  I notice one is a switch.  Though the specs do  not require equal MTU (like OSPF does) Cisco routers have been known to drop EIGRP packets over MTU mismatch issues.
The K-value mismatch error can be caused when the near side router does not support the “goodbye” message, added around 12.2(3), but the far side does.

HTH,

The interfaces appear to be in the correct vlans as per the solution.

I am working on IE II lab 1 task 3.6. I started with the cat then frame, rip and I am on eigrp (switch to router). I’ll do eigrp router to router next then move on to OSPF.

On the routers I left the MTU at default,m 1500. On the switches (3550/3560) I set the system MTU to 1500 (system MTU 1500 or system MTU routing 1500. Where allowed on the interface I set ip mtu 1500).

Debugs don’t show me anything. I was looking to shut the messages off with a command similar to ip ospf mtu-ignore but I don’t see one under the interface.

I can try and set the metric for all devices in the AS and see what happens.

From R5 I can not ping 183.1.105.10. From SW1 I can ping 183.1.105.10. R5 is connected to SW1.

When does it happen? After you change a parameter? I think I have seen the issue that Bob talked about with the goodbye message causing a K-value mismatch….It looks like you are getting the K-value mismatch, then your adjacency is forming. This means your adjacency was brought down for some reason – maybe you configured a summary or secondary address…

Example: I had an initial config with a mistake (on purpose). One router on a LAN with /24 and the other with /20 mask. After I configured the /20 for a /24, EIGRP sent a goodbye and the other router complained about a K-value mismatch. The adjacency then came up fine.

I wonder if its a code issue…I am always running 12.4…

What is the mask of each interface?

Is the mask 255.255.255.248 on one end and something else on the other?

Let’s focus on the basics.

You said “From R5 I can not ping 183.1.105.10.”

SW1 as far as I can tell is not routing between SW4 and R5 so we do not care about its routing table or whether it can ping any address. Sw4 and R5 should have a layer 2 path somewhere. What is that path?

Solve this issue first.

Piotr,

Try consistent speed and duplex. Either both sides negotiate or both sides locked down.

Are you sure that SW4 f0/18 is connected to SW1 f0/15…?There seems to be another switch involved because SW1 is trunking on f0/15….show cdp neighbor, something funny’s going on

As a side note you should have verified that R5 and SW4 could ping each other before moving on to routing. I learn the hard way too :)

I removed routing and checked my trunks. Everything looks ok.

On sw1 f0/5 I added 183.1.105.55/24 and I could ping that from R5.

I ran out of rack time……

Thanks everyone.
