IP6Encap

encapsulates packets in static IP6 header

SYNOPSIS§

IP6Encap(PROTO, SRC, DST, KEYWORDS)

Ports: 1 input, 1 output
Processing: agnostic

DESCRIPTION§

Encapsulates each incoming packet in an IP6 packet with next header proto PROTO, source address SRC, and destination address DST. Its destination address annotation is also set to DST.

As a special case, if DST is "DST_ANNO", then the destination address is set to the incoming packet's destination address annotation.

Keyword arguments are:

• HLIM — Integer, The hop limit of the packet with maximum value of 255
• CLASS — Integer, The service class of the packet. Used for QoS

EXAMPLES§

Wraps packets in an IP6 header specifying IP protocol 4 (IP6-in-IP4), with source 2000\:10\:1::2 and destination 2000\:20\:1::2, HLIM is set to 20 hops:

  IP6Encap(4, 2000:10:1::2, 2000:20:1::2, HLIM 20)

You could also say "IP6Encap(ipip, ...)".
