| ====> | <------------ | | 1.ICMP Echo Request
| <==== | ------------> | | 2.ICMP Echo Reply (*1)
| | | | |
1. Send ICMP Echo Request. (out: HA0 -> NUTX, in: R2 -> NUT0)
2. Receive ICMP Echo Reply. (out: NUTX -> HA0 in: NUT0 -> R2)
Packet Format is:
1.ICMP Echo Request Data is:
IPv6 header (source = home agent,
destination = care-of address)
ESP header
IPv6 header (source = correspondent node,
destination = home address)
ICMPv6 Echo Request
2.ICMP Echo Reply Data is:
IPv6 header (source = care-of address,
destination = home agent)
ESP header
IPv6 header (source = home address,
destination = correspondent node)
ICMPv6 Echo Reply
(*1) PASS: HA0 receives the ICMP Echo Reply by reverse tunneling.
(*1) PASS: HA0 does not receive the Home Test Init and R2 does not receive the Care-of Test Init.

11.6 Return Routability Procedure
This section defines the rules that the mobile node must follow when
performing the return routability procedure. Section 11.7.2
describes the rules when the return routability procedure needs to be
initiated.
11.7.2 Correspondent Registration
(snip)
A mobile node MAY also choose to keep its topological location
private from certain correspondent nodes, and thus need not initiate
the correspondent registration.
8.5 IPv6 Mobile Nodes
(snip)
o The node MUST allow route optimization to be administratively
enabled or disabled. The default SHOULD be enabled.
