# This script evaluates IOAM for IPv6 by checking local IOAM configurations and
# IOAM data inside packets. There are three categories of tests: LOCAL, OUTPUT,
# and INPUT. The former (LOCAL) checks all IOAM related configurations locally
# without sending packets. OUTPUT tests verify the processing of an IOAM
# encapsulating node, while INPUT tests verify the processing of an IOAM transit
# node. Both OUTPUT and INPUT tests send packets. Each test is documented inside
# its own handler.
#
# The topology used for OUTPUT and INPUT tests is made of three nodes:
# - Alpha (the IOAM encapsulating node)
# - Beta (the IOAM transit node)
# - Gamma (the receiver) **
#
# An IOAM domain is configured from Alpha to Beta, but not on the reverse path.
# Alpha adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop.
#
# ** Gamma is required because ioam6_parser.c uses a packet socket and we need
# to see IOAM data inserted by the very last node (Beta), which would happen
# _after_ we get a copy of the packet on Beta. Note that using an
# IPv6 raw socket with IPV6_RECVHOPOPTS on Beta would not be enough: we also
# need to access the IPv6 header to check some fields (e.g., source and
# destination addresses), which is not possible in that case. As a
# consequence, we need Gamma as a receiver to run ioam6_parser.c which uses a
# packet socket.
