Dear Mr. Andrew Yourtchenko, Thanks for the review. We have checked the actual packets created.
``` create tap set interface state tap0 up set ip6 address tap0 2001:db8::/64 ip6 nd tap0 prefix 2001:db8::/64 14400 12600 ip6 nd tap0 no ra-suppress ``` The result of rdisc6 at this time was this. (pcap is also available in the attachment) ``` rdisc6 tap0 Soliciting ff02::2 (ff02::2) on tap0... Hop limit : 64 ( 0x40) Stateful address conf. : No Stateful other conf. : No Mobile home agent : No Router preference : medium Neighbor discovery proxy : No Router lifetime : 600 (0x00000258) seconds Reachable time : unspecified (0x00000000) Retransmit time : unspecified (0x00000000) Source link-layer address: 02:FE:A7:E5:46:11 MTU : 9000 bytes (valid) Prefix : 2001:db8::/64 On-link : Yes Autonomous address conf.: Yes Valid time : 14384 (0x00003830) seconds Pref. time : 12584 (0x00003128) seconds from fe80::fe:a7ff:fee5:4611 ``` The decrement_lifetime_flag/deprecated_prefix_flag is 1, so the packet looks correct.
