Hi Domagoj,

Premec, Domagoj wrote:
> I was thinking of both the IP and the link-layer address. From the host perspective, this looks similar to the case where the current default router goes down and at the same time a new default router appears on the link. I'm not sure about the case where both ARs are using the same IP address but their link layer addresses are different. Updating only the link layer address while the IP address remains the same may be considered as a special case, but I'm not sure if there are any security considerations.

PMIP requires all the ARs(i.e. MAGs) to have the same link local and 
link layer addresses as described in section 6.9.3 of RFC5213. Things 
may not work otherwise.

Thanks
Suresh
