I am using Cisco Packet Tracer to simulate a network of two routers each connected to a switch and two hosts per switch. The network is setup as so:
I'm using a default subnet mask of 255.255.255.0
. Between router to router, they can ping each other successfully. Between computers on the same switch, they can ping each other successfully. However, when I try to ping PC7 to PC1 for instance, or vice versa, the requests time out. The IP Address of the Seattle Router is 23.12.0.1/24
and Van Nuys is 23.12.0.2/24
. I think it might have something to do with the ip route
command, but I feel like I've tried everything and still won't work.
Any ideas?
23.12.0.0/24
network that originates on that network will never go through the router.% 23.12.0.0 overlaps with FastEthernet0/0
23.12.0.0/24
network in Seattle, you must have a different network in Van Nuys. Then, you can configure routes in your routers to get to the other network. You cannot route from a network to the same network.23.12.0.0
into four subnets, I got one of the network IDs to23.12.0.192
... I suppose that means it's telling me it's still on the same network. Isn't this IP considered class A? I've only been subnetting class C networks before...23.12.0.0/24
network into four equal subnets. See this question and the excellent answer for how to do this. You really must learn subnetting (become an expert) before you try routing.
