I have a strange problem with a very simple network that has stumped me and hoping someone can shed some light. Probably a brain fade, but got me beat
2 x 1720 routers connected via a frame.
Router A config :
F/E 0 = 192.0.0.1/24
Serial 0 = 192.168.200.2/30
F/E 0 connected to Cisco 2924 switch
Router A default gateway = 192.168.200.1
Router has RIP version 2 enabled with networks 192.0.0.0 and 192.168.200.0 being broadcast.
Router B config:-
F/E 0 = 192.168.1.1/24
Serial 0 = 192.168.200.1/30
F/E 0 connected to hub
Router default gateway = 192.168.200.2
Router has RIP version 2 enabled with networks 192.168.1.0 and 192.168.200.0 being broadcast.
Switch Config (located behind router A):-
Switch has IP address = 220.127.116.11
Switch default gateway = 192.168.200.2
Router A (via switch) workstation(s) config:-
default gateway = 18.104.22.168 (to the switch)
Router B workstation config:-
Default gateways set to 192.168.1.1 (have tried 192.168.200.1 as well)
OK (apologies for the lengthy detail)
From Router B I can ping router A and workstations beyond Router A
From Router B I can traceroute to workstations behind router A and the switch, which is good. To my thinking there is a route to and from Router B through Router A, through the switch, to the workstation and then back again.
Problem is from Router A..(and anything behind router A)
I can ping workstations beyond Router B (via the hub), but I cannot traceroute to any devices behind Router B.
Im struggling to see what the reason is. I understand ping is different to traceroute, but I can FTP to the devices I am trying to traceroute to..weird...
Its causing some problems with an application we are running where comms are OK between Router B to A...but fail from Router A to B ( well, the devices behind router B ).
I can traceroute to each one of the routers..the problems happen when I try to get to devices beyond router B.
Confused!!?? I am just reading this, but hopefully someone will be able to help.
BTW, the workstations in question (behind router B) are running DOS and TCP/IP (PCTCP)
Any ideas folks???
Really appreciate any assistance...

Your pcs and switch should have the def. gw of their local router. Switch and pc's at site A should have 192.0.0.1 as their gw. At B the gw should be 192.168.1.1.

U seems to be messed up in ur problem. Well..i m trying my hand in it...since i m a novice worker on routers and just got CCNA certified...cant say that my solution will really work for u...but still trying my hand to help u out.
Well...first of all....do write "no auto-summary" command in config mode in both the routers. Then, check out the address of F/E port in Router A. I think...its not the right address to be mentioned...please check it out.
Hope this helps u...
Best of luck to u & me too...since this is the first time I m trying my hand

I think the switches default gateway is set wrong. SHould be 192.0.0.1 and not 192.168.200. whatever.....
I`ll give this a whirl and see how it goes.
Strange though that if I can trace from one system to the other, but not the other way around. Surely if theres a path to and a return path from the device, then it works both ways...
Thanks very much guys...I`ll see how it goes
