I have been messing with GNS trying to figure out router on a stick and ran into some trouble. I can ping from the router acting as the core to any address within every vlan. The problem exists when I try to ping from an ip within lets say an ip in vlan 10 to an ip in vlan 20.
Basically Ive set up 3 different vlans 192.168.10.0/24, 192.168.20.0/24 and 192.168.30.0/24. Withing those three vlans there are 2 "PC's" each with the following addresses : 192.168.10.0/24 (192.168.10.2, and 192.168.10.3), 192.168.20.0/24 (192.168.20.4, and 192.168.20.5), and 192.168.30.0/24 (192.168.30.6, and 192.168.30.57).
Because I do not have switches I've been using a cicso 3660 with a 16esw slot to act as one.
I have set up port f1/0 on the "switch" as a trunking port and also added the vlans to the database. Port f0/0 on the router core is sub interfaced f0/0.1 for vlan 10, f0/0.2 for vlan 20 and f0/0.3 for vlan 30. I also didnt assign an address to f0/0 but brought it up so it was active.
Could there be something I am doing wrong that is obvious? Ill include my topology and configs for any extra information. I am thinking there may be something wront with my route, due to the fact the router core is conencted to all the vlans.
