tunnel allow-remote {ip-address | ipv6-address} [mask]
Use the no tunnel allow-remote command to delete a congured allow-remote entry. Any specied address/mask
values must match an existing entry for the delete to succeed. If the address and mask are not specied, this
command deletes all allow-remote entries.

ipv6–address Enter the source IPv6 address in X:X:X:X::X format.
