Deleting an IP Address from an Interface Configured as a Tunnel Source

To delete an IP address from an interface that is configured as a tunnel source, first remove the tunnel source from the tunnel interface then delete the IP address, as shown in the following example.

device(config-if-e1000-1/1/3)# interface tunnel 8
device(config-tnif-8)# no tunnel source 10.1.83.15
device(config-tnif-8)# interface ethernet 1/1/3
device(config-if-e1000-1/1/3)# no ip address 10.1.83.15/24

If you attempt to delete an IP address without first removing the tunnel source, the console will display an error message, as shown in the following example.

device# config terminal
device(config)# interface ethernet 1/1/3
device(config-if-e1000-1/1/3)# no ip address 10.1.83.15/24
Error - Please remove tunnel source from tnnl 8 before removing IP address
