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 = 188.8.131.52
Switch default gateway = 192.168.200.2
Router A (via switch) workstation(s) config:-
default gateway = 184.108.40.206 (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...
