Router problem

I have set up 2 cisco 2600 routers. interface 0/0's are conncted with a crossover cable to simulate Wan. and interface 0/1 has a laptop on each side.

the problem is when i ping Laptop 1 from Laptop 2 the ping woks only for about 5 minutes, and then stops for no reason that i can see, if i refresh the access list (take off and then apply it again) ping starts again for another 5 minutes, i have tried 2 other routers and the same issue occurs.can anyone shed any light on this?

Hi,

RIP updates are not allowed to pass by the ACL. After some time the route is removed from the RIB.

Is ACL CCNA? I haven't encountered it yet. Or is it CCNP?

Hi,

As far as I know they are in the curriculum.

He is talking about IP permit statements. However, I would think that it might actually be interface speed or physical layer (bad cable or connection). Try hard-setting the ports both speed and duplex. Look for interface errors to confirm (sho int) .

Hope this helps.

Robert.
