[OOR-Users] How to set the merge flag in registration messages?

[Albert López]

Hi Holger,

Unfortunately OOR doesn't support more than one xTR per site.
To set the merge bit according to a parameter of the configuration file 
could be easily implemented. I am not sure if the logic behind this  is 
so easy to do.
I suppose that the Map Server will reply the Map Register with a Map 
Notify containing all the RLOCs of the xTRs of the site. The xTR can use 
the received Map Notify to learn of the other xTRs. What I don't know is 
what happens if an RLOC of an interface changes. How does the Map Server 
knows  that it should replace the RLOC and not add a new one?
What should xTR do with the new learned locators (R bit)?
As you have said, it is not only to set the merge bit in the map register.

Best regards

Albert
