Our network is currently using the 192.168.1.0/24 IP address range. I want to migrate to a network that will support more than 254 hosts. I'm thinking about using 10.11.0.0/16.
Although both networks will be on the same wire, they won't be able to talk to each other unless I implement some sort of routing between them. We have an ASA5510 as our main firewall, but it won't route between 2 internal networks so I can't use that. I've got a 3550 switch that will do layer 3 routing. What would be the best way to set this up?
This is what I was trying to do. Connect the 3550 to the rest of the network and give that connection an IP address of 192.168.1.250. Set the IP address for VLAN1 to 10.11.0.254.
ip address 192.168.1.250 255.255.255.0
ip address 10.11.0.254 255.255.0.0
On my workstation I add a route to the 10.11.0.0 network via 192.168.1.250. On a computer on the other network make 10.11.0.254 the default gateway.
So far so good. From my computer I can ping 192.168.1.250 and 10.11.0.254. From the other computer I can ping 10.11.0.254 and 192.168.1.250, but I can't seem to ping from one computer to the other from either direction.
Is there a better way of doing this?
