I am trying to set up a simple network with GNS and virtualbox. I have attached the topology along with the IP scheme.
R1 LAN = /16
R2 LAN = /24
R3 LAN = /24
Serials = /30
The only thing I have configured on the routers is the interface IP addresses and added a route of 0.0.0.0 0.0.0.0 to the routers R2 and R3.
When I ping from a VM on the R1 LAN, I can ping all the way to R2 & R3's serial interfaces.
However, if I ping from a VM on the R2 or R3 routers, can only ping to the serial interfaces from the LAN on that router. So from 192.168.1.4 I can only ping as far as 192.168.0.2 and 192.168.1.5 can only ping as far as 192.168.0.6.
Why would I be able to ping further from the computer attached to the R1 router?
All are 2691 routers with the exact same IOS.
