I hope you can help me out a little bit here (and I hope I can make myself clear).
I have a 2821 Router, with a NME-X-23ES-1G card. I also have a 2960 24 port switch.
My network is 18.104.22.168 with a subnet mask of .192.
I have configured the Gi0/0 port on the 2821 as IP 22.214.171.124.
I have configured the Vlan on the NME-X-23ES-1G card as IP 126.96.36.199
I have configured the 2960 Gi0/1 as 188.8.131.52
So far so good.
Now to connectivity.
I have a cross over cable coming from the 2821 Gi0/1 port to the GE1 (external label) port on the NME-X-23ES-1G. This works and I have connectivity. However I am wondering if I have to do this in this manner or can I somehow configure the 2821 router to talk to the NME-X-23ES-1G on the backplane or an internal port, without having to utilize the GE 1? Or am I locked into using the GE 1 port of the NME-X-23ES-1G in this manner?
My other question relates to the best way to connect the 2960 switch. Right now I have a crossover cable going from the FA1/0/2 port on the NME-X-23ES-1G to the Gi0/1 port on the 2960. This works, but it seems like it's not ideal. I would prefer to have the cable go from the Gi0/1 port on the 2821 to the Gi0/1 port on the 2960. However I can not get this to work. If I assign an IP address to the Gi0/1 port on the 2821 router I get an IP overflow error. If i just leave it all at defaults, I get connectivity lights on both ends, but no pinging can be done.
I assume I need to enter some commands on the 2921 Gi0/1 port so it can route or forward to the Gi0/0 port.
I should be able to do this, right?
