Dear developers,

According to the EIGRP draft RFC
(https://tools.ietf.org/html/draft-savage-eigrp-04#section-6.8.1), 2nd bit
(0x2) in EIGRP classic bit field should be interpreted as Candidate Default
(CD). At the moment the bit is ignored. I attached two dumps with set/unset bit
packets. As I understand, it should be defined in 'PDM opaque flag field
definitions' block (packet-eigrp.c). Thank you in advance!

Kind Regards,
Garri
