please i try to figure out what could be wrong but having issues. 2 nodes connected to switch 1 and 2,
I. from router 1 and 2 ROUTING TABLE,rip routes are not available why ?
2.i cant poing from node 1 to 2 but could do a telnet from 1 to2
3.i can ping fron node 2 to but sometimes have issue doing telnet to node1 it goes on and off.
please can anyone check config files and check where my mistakes are.thanks for anticipated help

firstly - you are being creative with the 192.168.10.x subnet.
I take it this is a lab?
Secondly you are using layer 3 interfaces on the switches? I presume rt1 connects to sw1, then sw1 connects to sw2 and sw2 connects to rt2 ??
RIP ver 2 uses multicast to find neighbours.
RIP looks for a neighbor locally attached.
Enable rip on sw1 & sw2 - observe the results.

You say that telnet is not consistent / flappy ?
1. Could you pls do a sh interface x and check for errors ?
2. Duplex mismatch ?
3. Any access-lists applied ?

no access rule applied but found errors as indicated below.so how can i rectify the problem,coulds be reason why i cant ping from node 1 to 2 but telnet and the flapping of telnet from 2 to 1.

Does RT1 DIRECTLY connect to RT2? not going thru any switches?
04-13-2010 05:05 AM
thanks for the feedback,r1 connects to r2 through the switch

Olkanule06,
I think you've got a couple of layer 1 and 2 problems as well as an underlaying design problem. Switch1 can only see switch2 from cdp which to me says you haven't got all the connectivity you need anyway. All your subnets that you have in your network are directly connected to both routers. thus you'll never see them as Rip routes anyway.
As this is a lab network remove the complexity to get the basics of level 1 and 2 connectivty down pat. I would remove 1 of the switches, and get the routers talking together on the same network. then add unique networks via loopbacks on R1 and R2 to see the subnets being advertised to it's opposite number.
