notify remote device about Xauth

[vamsi <vamsi@xxxxxxxxxxxxx>]

Hi,

It is neccessary  that edge device should  inform the   remote device  that Xauth follows once after completing the phase 1 exchange . (this is what they specified in Xauth draft)

We are any how  exchanging the vendor Id payload in the first two messages of phase 1   which is

sufficient   to notify a remote device  that 'Xauth ' follows   once after completion  of  Phase 1 exchanges.

In the Xauth draft  they specified two methods to notify the remote device  about Xauth :

1)Notification payloads with in Phase 1 exchange.

2)Notification  via Authentication Type.

My question is why    to  use    above two methods    even  though we already have  'Vendor ID ' option to notify  the remote host about  'Xauth'  ?

Which  method is more justified  to notify the remote device about Xauth  either by using 'Vendor Id' or 'Notification payload ' or  'Notification via Authentication types' ?

bye
