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 tunnel—mode command fails
unless the decapsulate-any option is included.
Configuration of IPv6 commands over decapsulate-any tunnel causes an error.
tunnel source
Set a source address for the tunnel.
