• 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.
ipv6–address Enter the source IPv6 address in X:X:X:X::X format.
mask (OPTIONAL) Enter a network mask in /prex 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 specied address.
Defaults If you do not congure tunnel allow remote , all trac which is destined to tunnel source address is decapsulated.
