multiple IP headers with NON-Random IP-ID

 

If the ROHC decompression context is initialized with IPv4/IPv4/UDP/RTP
and both RND flags were set to ZERO in the dynamic chain of the IR packet,

I'm not sure how the decompressor will be able to get the IP-ID of the outer
IP header because it will use the Offset IP-ID decoding for the inner IP
header.

is this a valid assumption?? or the RND flag must be set to 1 for at least
on of the two IP headers?
