NOTE: The ipv6 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.
Usage
Information
The ipv6 unnumbered command will fail if the tunnel interface already has an explicit IPv6 address
assigned. Likewise the ipv6 address command will fail if ipv6 unnumbered is already configured.
While unlikely, an interface can be configured to be ipv6 unnumbered for IPv6 while also having an
explicit IPv4 address.

tunnel allow-remote
Configure an IPv4 or IPv6 address or prefix whose tunneled packets are accepted for decapsulation. If you do not configure
allow-remote entries, tunneled packets from any remote peer address is accepted.
This feature is supported on Dell EMC Networking OS.
Syntax
tunnel allow-remote {ip-address | ipv6-address} [mask]
To delete a configured allow-remote entry use the no tunnel allow-remote command. Any
specified address/mask values must match an existing entry for the delete to succeed. If the address
and mask are not specified, this command deletes all allow-remote entries.
Parameters
ip-address Enter the source IPv4 address in A.B.C.D format.
ipv6–address Enter the source IPv6 address in X:X:X:X::X format.
mask (OPTIONAL) Enter a network mask in /prefix format (/x) or A.B.C.D to match a
range of remote addresses. The default mask is /32 for IPv4 addresses and /128
for IPv6 addresses, which match only the specified address.
Defaults By default there are no tunnel allow remote entries.
