How to create additional networks on layer 3 Cisco switch
I have a layer 3 Cisco switch that is on a 192.168.10.x network. I need to create two additional networks on this switch that I can route out to another site which is connected by an ASA firewall. How do I create the two additional networks which are 172.16.5.x and 172.16.15.x. Below is a diagram. Thanks

I want those two segments to be internal to my LAN but reachable from the other site. Do I need to assign ports to the VLANs? Can you explain a little bit more to clarify? Thanks

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Keep in mind to also add static routes on the ASA, pointing to the switch as the next hop.
I assume the 192.168.10.x network is not directly connected on the ASA either, so the routes for the new networks would look similar to the route for 192.168.10.0/24

Worked like a charm. Tnx!
If this is the case, you would just need the routes created in your l3 switch..
example:
ip route 172.16.15.x 255.255.255.0 172.16.16.4 (where 172.16.16.4 is actually the internal interface of the ASA)
If however, you are actually wanting to create new vlans on your l3 switch and for those two segments to be internal to your network.. you would just need to create the l2 and l3 vlan settings..
example.
vlan 15
interface vlan 15
ip address 172.16.15.254 255.255.255.0
