Deleting an IP address from an interface congured as a tunnel source
To delete an IP address from an interface that is congured as a tunnel source, rst 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 rst 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
NOTE
The previous error message will also display on the CLI when an interface is part of a VLAN. A VLAN cannot be deleted until
the tunnel source is rst removed.
Conguring the destination address for a tunnel interface
The destination address should be the address of the IP interface of the device on the other end of the tunnel.
To congure the destination address for a specic tunnel interface, enter commands such as the following.
device(config)# interface tunnel 1
device(config-tnif-1)# tunnel destination 131.108.5.2
Syntax: [no] tunnel destination ip-address
The ip-address variable is the destination IP address being
congured for the specied tunnel.
NOTE
Ensure a route to the tunnel destination exists on the tunnel source device. Create a static route if necessary.
Enabling GRE encapsulation on a tunnel interface
To enable GRE encapsulation on a tunnel interface, enter commands such as the following.
device(config)# interface tunnel 1
device(config-tnif-1)# tunnel mode gre ip
Syntax: [no] tunnel mode gre ip
• gre
species that the tunnel will use GRE encapsulation (IP protocol 47).
• ip species that the tunneling protocol is IPv4.
NOTE
Before conguring a new GRE tunnel, the system should have at least one slot available for adding the default tunnel MTU
value to the system tables. Depending on the conguration, the default tunnel MTU range is ((1500 or 10218) - 24) . To check
for slot availability, or to see if the MTU value is already congured in the IP table, use the show ip mtu command.
