I am connecting a 6509(10.x.x.x network) to a 3550(192.168.x.x network). I enabled ip routing. What else would I need to do to have the 2 switches communicate with each other, and other end devices too?
Also on the 3550, all the porst besides fa0/1 are configured to vlan 187. Ports fa0/1 on both switches are set to trunks and both switches are connected through fa0/1.
It would be the first option. I changed port fa0/1 back to regular ports. I added vlan188 which is a /30 network to connect the switches together(192.168.190.1,2). 1 being on the 6509, and 2 being on the 3550.
I also added static routes to both switches:
6509: ip route 192.168.0.0 255.255.0.0 192.168.190.2
3550: ip route 0.0.0.0 0.0.0.0 192.168.190.1
Also plugged in a laptop to the 3550switch and configured the ip address to 192.168.187.43 and the default gateway to 192.168.190.2.
My Desktop is on the 6509 switch with an ip address of 10.5.100.5 and a default gateway of 10.5.1.1.
I am still unable to communicate with the laptop.
Laptop default-gateway should not be 192.168.190.2 it should be the IP address assigned to the L3 vlan interface on the 3550 for the laptop vlan ie. it will be a 192.168.187.x address.
This only works if you are routing the 192.168.187.x subnet off the 3550.
As an aside if you are simply wanting a routed connection between the 2 switches which it sounds like you do then rather than use a dedicated vlan just make the 2 ports routed ports eg.
ip address 192.168.190.1
ip address 192.168.190.2
it would still work your way but you are extending L2 between the 2 switches and you don't need to if each switch is routing it's own vlans.
