Hi authors,

This is Yali. This is an interesting work. I have following two questions.

First, is the list of Namespace-IDs the subset or all of Namespaces which the IOAM encapsulating node belongs to? If it is, I suggest adding some words to illustrate this.

Second, could this extension to the echo request/reply mechanisms also be used in ICMP defined for IPv4?

In my opinion, as the Information Request and Reply Type=15 and Type=16 have been obsolete [RFC6918], so it could be used as the IOAM Capability echo request/reply messages to acquire the enabled IOAM capabilities.

Thanks,
Yali
