Weird ping issue.

[Synonix]

im going to try to explain this without doing a ton of Sh runs.

I got a lab im working on right now which has 2 routers and 2 switches. Routers are running back to back frame-relay. Literally everything communicates with everything else. I can ping from the switch on one one end of the network to the switch on the other. I have one computer connected to the lab right now on one switch and im trying to get this computer to communicate with the serial connection of the router that its connected to. The computer can ping the Ethernet IP on the router but cannot ping the serial connection IP. Any ideas? ive been tearing my hair out on this one because they USED to ping meaning i probably missed something small and cant catch it.

heres the routers Show Run:

Without seeing the rest of your lab config or a network topology the only thing I can see wrong here is the frame relay switch should be doing the clocking as the dce device not your router. That is assuming your lab setup is PC1-->Switch1-->Router1-->FRS<--Router2<--Switch2.

Do a show frame-relay pvc to see the status of your virtual circuits.

 

[Synonix]

your topology is correct. Im at work right now so ill add the pvc when i get home. Why should the switch be doing the clocking instead of the router?

 

[burtsbees]

That is not the topology---Vic---NO frame switch, just 2 routers back to back frame acting as the frame switch, I think.

This will not work without a third router in between acting as a frame switch---you must make the 2 routers simple PPP links, DCE doing clocking, and also, make the ethernet interface full duplex (assuming these are 2610's).

[Synonix]

i apologise, your right burt. there is no FRS in the middle.

PC1-->Switch1-->Router1-- B2B Frame Relay over Serial --Router2<--Switch2

i MIGHT have switched around the DCE DTE cables back when i was rearranging the lab on a rack. and if i flip flopped the connection and the clock is on the wrong side that MIGHT be why the computer dosent ping but... i mean that kinda makes no sense because i can ping from switch 1 to router 2 no problem.

 

[Viconsul]

You will need a third router to act as the frame relay switch for this type of lab, just as Burt mentioned.

 

[Synonix]

thats fine n all with the 3rd router but i should still be able to ping the outside IP of the router on that network from my computer. There is no frame relay involved in that request. its been done before with this setup and now i cant. as far as i can recall i changed nothing except when moving equipment.

PC1: 192.168.1.3/24 conected to fe0/2
Switch1: Vlan1 ip 192.168.1.1/24
Router1: inside eth0/0 192.168.1.2/24 connected to fe0/24 on switch. Outside 200.1.1.1/24

Router2: inside 192.168.2.2/24 connected to fe0/24 on switch2. Outside 200.1.1.2/24
Switch2: eventually ging to use as a loopback due to the fact i dont have any more PC's to use right now.

pc1 can ping only up to 192.168.1.2 not 200.1.1.1
Switch1 can ping everything on the network including the other side. UGH! makes no sense.

i doubt having a 3rd router installed will make pc1 able to ping 200.1.1.1

though i am in the market for a router that has SDM so ill probably have one soon enough.

PS. burt they are 2610's good guess

 

[Viconsul]

With the setup you currently have, the encapsulation you are using is wrong without a frs. You can use PPP or default (HDLC).
Do a no encapsulation frame-relay on se0/1 on both routers and ensure the router with the dce end has clock rate set.
Try this and it should be good.

 

[Synonix]

thnx vic will try when i get home.

 

[Cluebird]

Back to back FR will work fine without the intermediary switch. You need no keepalive on both sides. The gotcha is you must use the same DLCI on both sides of the circuit since you're disabling LMI on the b2b scenario.

 

[burtsbees]

Oh yeah, that's right...whoops... Been a while...

DLCI = 101 on both

No shut down on both

made sure the DCE is connected to the clocking router (r1)

im just out of ideas. i have NO CLUE how to explain this one. its like the router stops forwarding the packet the computer sent after it hits the routers Eth port on the router.

i mean i referred to this guide to get it all working and it did work.

http://www.cisco.com/en/US/tech/tk713/tk237/technologies_configuration_example09186a0080094a3b.html

now im just crippled with this ping issue.

 

[Viconsul]

On both Routers 1 and 2 post
sh int eth0/0 and sh int se0/1.1
Also ensure PC1 has the right GW and SM.
if it is connected to switch 1 and router1 is connected to switch1 and all swichport are in default vlan 1 then the ip configuration on your PC1 should be as below.

ip 192.168.1.3
sm 255.255.255.0
gw 192.168.1.2

 

[Caspiansails]

Do you have a default route defined? The most common issue with a device behind a switch and not being able to ping past the directly connected router on the switch is no default route or lack of a complete route table.

And yes vicon thats what my NIC is set for on the computer.

Also do the same for R1

Post this info...

Also, what can ping what?
1.pc1---SW1---R1------R2---SW2---pc2

Can pc1 ping R1's serial interface?
Can pc2 ping R2's serial interface?
If not...
Can pc1 ping R1 ethernet interface?
Can pc2 ping R2 ethernet interface?
If not, fix the obvious problem(s).

If all these are successful, then try and ping from pc1 to R2 serial, then ethernet interfaces, then from pc2 to R1 serial then ethernet interface. Post the results of the pings FIRST, then the results of the show commands...

There isnt a pc2 yet because i dont have another ethernet port to use. all switches and routers can communicate on every port. The only thing that dosent is PC1 to router1's serial IP and obviously anything beyond it. Note that it does ping to the router1's ethernet interface.

Heres requested info! thnx for the help

Put no auto-summary under router rip. Then try the pings again. They should work.

 

[Synonix]

Added the command. Didn't help. I think I'm going to flash the lab and start fresh. i got my ICND coming up on June 11th so i gotta just reinforce what i know and stop worrying about some BS like this. Its gotta be something with the computer it makes no sense that everything but the pc can communicate over the whole network.
