Subject: [IPFIX] RFC 5101bis - UDP checksum

Dear all,

Per RFC 768 and RFC 1122, UDP checksums are not mandatory.

Since the IPv4 checksum is only calculated over the header (not the 
data) and there is no IPv6 checksum, 5101bis should include a line 
recommending that UDP checksums are enabled when exporting over UDP.

P.
