I'm just starting out with the whole CCNA thing and I've been playing with Routersim. To start I thought I'd do a basic setup - unfortunately it doesn't seem to work as I expected.
The setup is;
[HOST A - 10.2.0.2/16 GW.10.2.0.1]
[int fastEthernet 0/0 10.2.0.1/16]
[int fastEthernet 0/1 10.1.0.1/16]
[HOST B - 10.1.0.2/16 GW 10.1.0.1]
I don't have the IOS config offhand. Basically I've configured the interfaces and made sure they are "no shutdown". I can ping both hosts from the router, which tests the ethernet connectivity. I just can't ping host->host when the traffic traverses the interfaces.
I then thought it'll be because there are no static routes. So I added them;
ip route 10.1.0.0 255.255.0.0 10.1.0.1
ip route 10.2.0.0 255.255.0.0 10.2.0.1
I did a "copy run start" and reloaded the router. Still I cant ping host->host.
When I do a show IP route, it displays the two interfaces and their subnets as connected, it also displays the static routes I've added.
Is this a limitation of the routerSim software and is my config correct? Or have I missed something really obvious?
I havent got access to any "real" routers for another week or so.
I can ping its default gateway, I can ping the other interface (0/1), unable to ping HostB
From HostB :
I can ping its default gateway, I can ping the other interface (0/0), unable to ping HostA
So it seems its not routing the traffic out of the opposite interface. I've checked the IPConfigs on both hosts and their IP/Subnets are set correctly.
HostA - 10.1.0.2/16 gw 10.1.0.1
HostB - 10.2.0.2/16 gw 10.2.0.1
The show ip route displays;
Gateway of last resort is not set
10.0.0.0/24 is subnetted, 2 subnets
C 10.2.0.0 is directly connected. FastEthernet0/1
C 10.1.0.0 is directly connected. FastEthernet0/0
By interface encapsulation do you mean PPP, framerelay or suchlike? Would that matter on a plain jane ethernet network?
There are no access lists in place.
The only oddity is when i do a show interface command, interface 0/1 displays a 0.0.0.0 for its internet address, yet shows as 10.2.0.1 in the config and it responds to a ping! There are no duplicate addresses on hosts or anything.
Starting to look like its a routerSim problem, or have i missed something
