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.
tunnel source
Set a source address for the tunnel.
Syntax
tunnel source {ip-address | ipv6–address | interface-type-number | anylocal}
To delete the current tunnel source address, use the no tunnel source command.
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.
