PDU test and ping test fail in simple network test in packet tracer

Hi,

I am new to packet tracer so please bear with me. I am testing out this simple network, but it seems to fail. I have rip routing enabled, so i'm not sure if i need static routing as well. Thanks!

Problem is that you have so called dis-contiguous network with 100.100.100.x/8 (100.0.0.0/8) on right of R1 and left as well. Same thing with 10.0.0.0/8 off R1.  it is on both sides;going from left to right we have

100.0.0.0/8 , then 10.0.0.0/8, then  R1 has  10.0.0.0/8 to left and 100.0.0.0/8  to right side. then 100.0.0.0/8 and

10.0.0.0/8 on ISP. 

this created major problems with RIP version 1 which was one of reasons for update of RIP to version 2. also , no auto-summary should help but it does not in your case.

Based on above findings, change networks and keep 100.0.0.0/8 of left of R1 and 10.0.0.0 on right side of R1. perhaps You could also change mask for class A making other class networks.

ip default-gateway 10.10.10.41 is wrong and not needed. also default-information originate does not do anything in your case.

cannot see topo, pic too small. it's easier if you attach your file here; You can attach your PT file but it must be in a zip format.

Hi! changing the networks seemed to fix it. Thanks for your help!

np, btw, not a PT bug.

TS steps:1 ping default gateway, then trace your destination to see problem.  both end hosts get to default gateway (d.g) routers but not beyond.  next step would be pings/trace from those d.g. routers.  I think that problem seems to be on R1;  its pointing wrong way.  it says to reach PC use GigabitEthernet0/0 - wrong! and vice versa. not sure why yet.
