Enable tunnel in RFC 2003 mode and encapsulate IPv4 and/or IPv6 datagrams

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 define a tunnel mode for the tunnel to function.
If you previously defined 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 configured: tunnel destination, tunnel dscp, tunnel flow-label, tunnel hop-limit, or tunnel
keepalive. Conversely, if you configure any tunnel allow-remote entries, the tunnelmode command
fails unless the decapsulate-any option is included.
Configuration of IPv6 commands over decapsulate-any tunnel causes an error.
