I am testing interoperability with one major vendor=92s VRRPv3 IPv6
implementation and was surprised to  find that the vendor=92s unit does not
include an IPv6 pseudo-header along with the VRRPv3 packet data when
calculating the checksum.   The current version of Wireshark (1.6.7) also
shows the VRRPv3 checksum as incorrect.  This would probably only be an
issue when trying to interoperate with another vendor=92s implementation.



I=92m interpreting RFC-5798 section 5.2.8 to say to calculate the checksum
over both the VRRPv3 packet data starting with the version field, AND over
the IPv6 pseudo-header (source, destination IPv6 addresses, upper layer
packet length, zero field, and next header of 112 for VRRP.)



Can someone on this mailing list verify my interpretation?



Thanks,

Joe McFarland
