+# This test evaluates the IOAM insertion for IPv6 by checking the IOAM data
+# integrity on the receiver.
+#
+# The topology is formed by 3 nodes: Alpha (sender), Beta (router in-between)
+# and Gamma (receiver). An IOAM domain is configured from Alpha to Gamma only,
+# which means not on the reverse path. When Gamma is the destination, Alpha
+# adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop and fills the
+# trace with its own IOAM data. Beta and Gamma also fill the trace. The IOAM
+# data integrity is checked on Gamma, by comparing with the pre-defined IOAM
+# configuration (see below).
