A tricky question as the destination of the tunnel is unknown and no privilege to see the running configuration on Sw3. One option to determine the destination address:
Rack1SW3> show interface tunnel 0 | in source
Tunnel source 183.0.50.147 (Loopback3), destination 183.0.2.1
Configure the tunnel destination
Rack1SW2(config)#int tunnel 0
Rack1SW2(config-if)#tunnel destination 183.0.50.147
Verify that the tunnel is operational
Rack1SW2#ping 10.0.0.3
Sending 5, 100-byte ICMP Echos to 10.0.0.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/5/9 ms
Another but less elegant way was to do a ’show ip interface brief’ on Sw3
