.
Syntax
tunnel mode {ipip | ipv6 | ipv6ip}[decapsulate-any]

Parameters
ipip Enable tunnel in RFC 2003 mode and encapsulate IPv4 and/or IPv6 datagrams
inside an IPv4 tunnel.
ipv6 Enable tunnel in RFC 2473 mode and encapsulate IPv4 and/or IPv6 datagrams
inside an IPv6 tunnel.

Command History
Version Description
9.7(0.0) Introduced on the S6000-ON.
9.3(0.1) Introduced on the S6000 and Z9000.
9.4(0.0) Added the decapsulate-any command.
Usage Information
To enable a tunnel interface, use this command. You must dene a tunnel mode for the tunnel to function. If
you previously dened the tunnel destination or source address, the tunnel mode must be compatible.
Including the decapsulate-any option causes the command to fail if any of the following tunnel transmit
options are congured: tunnel destination, tunnel dscp, tunnel ow-label, tunnel hop-limit, or tunnel
keepalive. Conversely, if you congure any tunnel allow-remote entries, the tunnel—mode command fails
unless the decapsulate-any option is included.
Conguration of IPv6 commands over decapsulate-any tunnel causes an error.
