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 the one of the address family.
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 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.

Usage
Information
You can configure up to eight allow-remote entries on any multipoint receive-only tunnel.
This command fails if the address family entered does not match the outer header address family of the
tunnel mode, tunnel source, or any other tunnel allow-remote.
If you configure any allow-remote , the tunnel source or tunnel mode commands fail if the outer header
address family does not match that of the configured allow-remote.
Usage
Information
Allow-remote entries can be configured only on multipoint receive-only tunnels, that is tunnel mode
includes decapsulate-any option. This command will fail if any bidirectional tunnel options are configured.
Likewise, attempts to configure bidirectional tunnel options will fail if any allow-remote entries are
configured.
