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

Command History

Version Description

9.4(0.0) Added the decapsulate-any command.

9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.

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.

Syntax

tunnel source {ip-address | ipv6–address | interface-type-number}
