Usage
Information
The ip unnumbered command fails in two conditions:
● If the logical ip address is configured.
● 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 configured
IPv6 address. The tunnel interface is not changed to operationally up until the logical IP address is identified from one of the
address family.
ipv6 unnumbered
Configure a tunnel interface to operate without a unique IPv6 address and select the interface from which the tunnel borrows
its address.
Syntax
ipv6 unnumbered {interface-type interface-number}
To set the tunnel back to default logical address use the no ipv6 unnumbered command. If the tunnel
was previously operational, the tunnel interface is operationally down unless you also configure the tunnel
IPv4 address.
Parameters
interface-type
interface-number
Enter the interface type, followed by the type, and then the slot/port/subport
information.
Defaults None.
