| | | | |
1. Send Router Advertisement. (HA0 -> HA0_allnode_multi)
2. Send Router Advertisement. (R1 -> R1_allnode_multi)
3. Receive Neighbor Solicitations(NUD). (NUT0 -> HA0)
4. (no reply)
# Wait during a maximum of 3 seconds(RFC2461).
5. Receive Binding Update. (NUTX -> HA0)
6. Send Binding Acknowledgement. (HA0 -> NUTX)
7. (wait)
# Wait during a maximum of the lifetime value in the Binding Update[5].
8. Send Router Advertisement. (HA0 -> HA0_allnode_multi)
9. Receive Neighbor Solicitation. (NUT0 -> HA0)
Packet Format is:
9.Neighbor Solicitation(DAD) Data is:
IPv6 header (source = unspecified address,
destination = solicited-node multicast)
ICMP Neighbor Solicitation
Type = 135
Code = 0
Checksum = (auto)
Reserved = 0
Target Address = link local address
(*1) PASS: HA0 receives Neighbor Solicitation(DAD).
Then, check whether this packet fills all of the following.
