Tunneling
Tunneling is supported on Dell Networking OS.
ip unnumbered
Congure a tunnel interface to operate without a unique IPv4 address and select the interface from which the tunnel borrows its
address.
Syntax ip unnumbered {interface-type slot/port}
To set the tunnel back to default logical address use the no ip unnumbered command. If the tunnel was
previously operational, the tunnel interface is operationally down unless you also congure the tunnel IPv6
address.
Parameters
interface-type
interface-number
Enter the interface type, followed by a slot number.
Defaults None
Command Modes INTERFACE TUNNEL

Usage Information
The ip unnumbered command fails in two conditions:
• If the logical ip address is congured.
• If Tunnel mode is ipv6ip (where ip address over tunnel interface is not possible).
To ping the unnumbered tunnels, the logical address route information must be present at both the ends.
NOTE: The ip unnumbered command can specify an interface name that does not exist or does not have a congured
IPv6 address. The tunnel interface is not changed to operationally up until the logical ip address is identied from one of
the address family.
