ISATAP and proto-41 in unmanaged networks?

[mariana.nikolova@philips.com]

Hi Fred, 

>It just now occurs to me that Christian's unmanaged networks presentiation during v6ops yesterday did not mention ISATAP as one of >the automatic tunneling alternatives, and I wonder why this is so.

I wonder as well. Not only ISATAP but also proto-41 (that Jordi presented later on) were not mentioned in the Christian's presentation. Keeping in mind that both mechanisms (ISATAP for intra-site tunneling and proto-41 for inter-site tunneling) are often used I asked myself why they were kept undercover yesterday. 

Probably some comments form the designing team of unmanaged networks proposal?

>ISATAP requires an ISATAP router in a site to advertise RA in apretty weird fashion, which is clearly a drawback.

Itojun, Teredo also requires quite an infrastructure (Teredo servers, Teredo relays) to function properly. In general this is valid remark for all transition mechanisms. However, it is not a reason to ignore some of them and to push others.  

Greetings, 
Mariana
