inner source RLOC undefined in some cases

Description

I am constructing the inner packet of a map request either because I'm
directly connected to the alt or because I'm going to send an outer
packet to the MR.

I need to construct a packet as the same IP version as the destination
EID I'm sending to.

It is undefined what RLOC I use for the source IP address in the inner
header if I have no RLOC of that address family.

For example I have v4 RLOCs and am sending to a v6 eid. It's
undefined what RLOC I should use in the inner header.

We should specify this. Except for receiving ICMP errors generated on the alt, it probably doesn't matter much, but it is a deficiency in the spec.

Joel ended up independently discovering this issue in his presentation for IETF 76. As far as I know there has been no discussion of how to fix.

Reply sent by Vince Fuller:

  • The description of the tracker issue appears to be incorrect; the issue appears to be related to incompatible address family usage between source and destination of Map-Request. Dino stated in a response on 9/22/2009 that this scenario represents a misconfiguration. If this is not an acceptable response then perhaps the issue should be listed in section 5 (Open Issues

and Considerations) as I don't have a solution. Alternatively, the issue owner is asked to propose a mechanism and provide suggested text.

Note: ticket will be closed Friday 25th March unless the responses noted here do not address the concern. If the concern is still not addressed substantive reasoning would be appreciated.
