Technical Summary
Network nodes may discard packets if they are unable to process
protocol headers of packets due to processing constraints or limits.
When such packets are dropped, the sender receives no indication so
it cannot take action to address the cause of discarded packets. This
specification defines several new ICMPv6 errors that can be sent by a
node that discards packets because it is unable to process the
protocol headers. A node that receives such an ICMPv6 error may be
able to modify what it sends in future packets to avoid subsequent
packet discards.
Working Group Summary
This document had good w.g. review, was discussed at several face to
face 6man sessions and on the list. The chairs also did individual
reviews. This found one important issue with the use of RFC4884. This
is fixed in the current draft.
Document Quality
No known implementations. Difficult to implement until the IANA code
points have been assigned.
Issues raised in reviews have been resolved in current draft.
Personnel
The Document Shepherd is Bob Hinden. The Responsible Area Director is Suresh Krishnan.
RFC Editor Note
RFC Editor Note
OLD:
Per [RFC8200], except for Hop by Hop options, extension headers are
not examined or processed by intermediate nodes. Many intermediate
nodes, however, do examine extension headers for various purposes.
NEW:
Per [RFC8200], except for Hop by Hop options, extension headers are
not examined or processed by intermediate nodes. However, in deployed
networks many intermediate nodes do examine extension headers for
various purposes.
