Help getting two "switches" to ping each other accross a trunk line

Hello Cisco Experts,

I’m using GNS3 to setup some labs.  The current lab I have consists of two routers with switch modules in them (so they can act like switches) connected to each other.  The routers are named ESW1 and ESW2.  On each device I have done the following:
•      Created a new vlan (vlan 10).
•      Created a vlan interface.
•      Assigned each vlan interface an IP address in the same subnet.  For ESW1 interface vlan10 has the IP address of 10.99.99.1 255.255.255.252.  For ESW2 interface vlan10 has the IP address of 10.99.99.2 255.255.255.252.
•      Configured interface fa1/0 as a trunk port
•      Allowed vlan 10 on the trunk.

At this point in time, ESW1 can ping its ip address of 10.99.991 and ESW2 can ping its ip address of 10.99.99.2.  However, EWS1 cannot ping 10.99.99.2 and ESW2 cannot ping 10.99.99.1.  I can’t figure out why this isn’t working.  I suspect it is because IP is layer 3 and trunking is layer 2.  This configuration is similar to one we have at work between our agency and a county agency, so I want to understand it.  Any help with this would be greatly appreciated.

Below are the running configs for ESW1 and ESW2:
