Subject: [6lo] handle mcast stateful compression above 64 bit prefix length

Hi,

I have a question about handling multicast stateful compression [0], when
the context prefix length is above 64.

So far I understand the context will be then the "prefix length and
network prefix" of "Unicast-Prefix-based IPv6 Multicast Addresses"
(rfc3306) [1] which is at maximum 64 bit long.

Is the right handling here: simple ignore it if the context has a prefix
above 64?

Thanks in advance.
