Conceptually, local switching is just local bridging. You are passively connecting two interfaces together the same way you would connect two devices to a switch in the same VLAN.

IOS17

 ip address 10.100.1.17 255.255.255.0
 
CSR8
interface GigabitEthernet4
 ip address 10.100.1.8 255.255.255.0
 
CSR1

Once the configuration is in place on CSR1, CSR8 and IOS17 should be able to ping/communicate with each other.
 
CSR8#ping 10.100.1.17
Type escape sequence to abort.
