Is there a limit to amount of sub interfaces which can be created on one router fastethernet interface

They are rotued on the router … ’show ip route’ on the router should show the two routes as connected. Hence, hosts on VLAN 100 should point to 192.168.100.1 as their gateway to VLAN 200, and hosts on VLAN 200 should point to 192.168.200.1 as their gateway to VLAN 100.

I tried creating sub-interface on a regular ethernet interface and it does allow you to create.

Interface IP-Address OK? Method Status Protocol
Ethernet0/0 155.1.58.5 YES manual up up
Ethernet0/0.1 unassigned YES unset up up
Serial0/0 155.1.0.5 YES manual up up

You do need FastEthernet interface. You cannot create a sub-interfaces from a regular Ethernet interface. So, you cannot use a router that doesn’t have a fastethernet interface in a router on a stick configuration

try using ISL as the encapsulation. And if the router has a AUX port you can get a dongle that will turn it into a ethernet/fast ethernet port
