ipv6 unnumbered
Congure 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 congure the tunnel IPv4
address.
Parameters
interface-type
interface-number
Enter the interface type, followed by the type, slot and port information.
Defaults None.
Command Modes INTERFACE TUNNEL

Usage Information
The ip unnumbered command fails in two conditions:
• If the logical ip address is congured.
• 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 ipv6 unnumbered command can specify an interface name that does not exist or
does not have a congured IPv6 address. The tunnel interface is not changed to operationally up
until the logical ip address is identied from one of the address family.
tunnel allow-remote
Congure an IPv4 or IPv6 address or prex whose tunneled packets are accepted for decapsulation. If you do not congure allow-
remote entries, tunneled packets from any remote peer address is accepted.
This feature is supported on Dell Networking OS.
Syntax
tunnel allow-remote {ip-address | ipv6-address} [mask]
To delete a congured allow-remote entry use the no tunnel allow-remote command. Any specied
address/mask values must match an existing entry for the delete to succeed. If the address and mask are
not specied, this command deletes all allow-remote entries.
Parameters
ip-address Enter the source IPv4 address in A.B.C.D format.
