Re: [Openpana-users] PANA with multiple pana relay element between PAA and Pac

[Francisco V. M. <f.v...@um...>]

Hi Apurva,

for relayed messages in multihop environments you only need a PRE between
the unauthenticated node and the authenticated network. Suppose the
following scenario where JN stands for Joining Node and AN stands for
Authenticated Node:

JN --- PRE(AN) --- AN ... AN ... PAA

Here, the PRE will encapsulate the messages from JN and send them in the
multihop environment given that it's an authenticated node. Is this your
case? otherwise I don't see why you need multiple PREs.

Regards,
Paco
