Local Switching

Picture
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
interface GigabitEthernet0/1
 ip address 10.100.1.17 255.255.255.0
 
CSR8
interface GigabitEthernet4
 ip address 10.100.1.8 255.255.255.0
 
CSR1
connect LOCAL GigabitEthernet3 GigabitEthernet5
 
CSR1#show connection
 
ID   Name            Segment 1              Segment 2                  State   
================================================================================
2    LOCAL           Gi3                    Gi5                        UP      
 
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.
Sending 5, 100-byte ICMP Echos to 10.100.1.17, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 10/12/15 ms
 
IOS17#sh arp
Protocol  Address          Age (min)  Hardware Addr   Type   Interface
Internet  10.100.1.8              1   5000.0008.0003  ARPA   GigabitEthernet0/1
Internet  10.100.1.17             -   5000.0011.0001  ARPA   GigabitEthernet0/1
 
The ping from CSR8 to IOS17 is successful.
