RIP Lab question

NCIT

Another newb issue question. I setup the RIP lab and had no trouble until I tried to connect a host to the routers. I can ping from router to router and do all the commands per the Lab. When I try to connect a host up to router A or B I can't get the PC to see either router. I set up the PC per the Lab but I think I either have a cable issue or I am not setting up the PC correctly.

I am using an AT-210T and cross-over cable (also tried regular Ethernet cable). With the cross-cover the router is up up but I can't ping. I had made the cross-over cable so I went out and bought a new one and no joy.

Any help with this would be greatly appreciated as I am also having no luck getting an AUI to work on my 2511-RJ router to my PC.

Go step by step:

1.) is the interface on the router active?
2.) what is the ip address?
3.) did you manually give the computer an ip address?
4.) a straight cable is what you need. Cross over is for like devices.
5.) From the computer can you ping the IP of the interface on the router?

Odd, without Auto-MDIX, I thought that the cable between a host and router would be crossover cable.

Whats the status of your interfaces with "show ip interfaces brief"? And are the routes listed in a "show ip route"?

NCIT

1.) is the interface on the router active?
RouterB#show int ethernet 0
Ethernet0 is up, line protocol is up
Hardware is Lance, address is 00e0.b05a.4930 (bia 00e0.b05a.4930)
Description: connected to LAN
Internet address is 192.168.33.1/24
2.) what is the ip address? PC doesn't come up with any IP within the range of above.
3.) did you manually give the computer an ip address? Yes I did originally, changed the network settings back to "obtain IP address automatically"
4.) a straight cable is what you need. Cross over is for like devices. Went back to regular cable and no joy, tried a new one and still no joy.
5.) From the computer can you ping the IP of the interface on the router? No

If you don't have a DHCP service on in that lab environment, you need a static IP address for the host and make sure it's in the same subnet as the router's address. Also, you may want to use a crossover cable for the link between the host and router unless there is something I'm forgetting. What does "show ip route" give?

Give your PC 192.168.33.10 255.255.255.0 and ping again?

Doh sorry, also please post from your router

show run interface ethernet 0

No RIP route in that output. Could you do a "show run"? And whats the other address space for your second network?

Ok, I can ping from my PC (host) to 192.168.33.1 (it also shows no yield sign on unidentified network). I am using a straight cable. When I try to ping from routerB it is unable to ping the host. Also I cannot ping to routerA. I also added in router A's ahow run. I think I grabbed everything.

Why didn't 192.168.33.151 work per the Lab?

There is no default gateway. That MAY be part of your problem.

I added the gateway in but I still can't ping from router A or B to the host (192.168.33.10). I shut off the wireless adapter so I didn't have any issues with it, plus when pasted it in it didn't leave the space.

You won't get that far as RIP isn't working right, the routes aren't in Router A to reach Router B's LAN. Can you ping across the link from Router A to Router B?

If yes, then
Turn your PC firewall off or allow icmp requests,

I changed hostB back to 192.168.33.151 and it works too. Whole problem was my firewall.

Thanks for the help!!

mattlee09

The thing is, seems like you learned something important about the troubleshooting (although it doesn't make the frustration regarding the firewall any less I know, been there done that myself).

I had a similar issue in a Boson sim I did earlier. Couldn't ping from Host B on one side of the network to Host A on the other, through 2 routers and 2 switches. After pinging each successive interface, I found that one of the router interfaces didn't have an address, and that one of the two was missing RIP configs, or something of the sort (did several mini labs/sims today, get them all mixed up).

Regardless - Ping is your troubleshooting friend, and be sure there will be more to come

Forgot about the fire wall. With it turned off I can ping from routerA to hostB.

When I was studying ccna,I had similar issue , when tried to send my backup routers config to server , and I couldn't do it...Spent an hour tried everything, apply settings over and over again, check cables, protocols, and than...finally found it

CodeBlox

If it isn't too late, could I ask what was wrong with RIP anyway? Your show IP route didn't have any RIP routes in it.

Jollycork

yeah, the routers aren't exchanging route info, so RIP still isn't working even though you can ping.

seems to me the gateways aren't specified on both routers. might try a static route on both routers.

ip route 0.0.0.0 0.0.0.0 [interface] or [addresses]

then post another sh ip route see if RIP now propogates routing info between each other.
