A quick question then:
How would you handle the cases where a Routing Header is to be processed?
In this case, the ROUTER has to go beyond the IPv6 header. Perhaps, even
processing a Hop by hop and/or destinations options header, prior to it
also.
It's tough to do in an ASIC, I agree. However, I still don't how you could
simply skip over the extension headers, and go directly to the transport
layer. I think the looping algorithm is your best option.
On a side note: typically, how many addresses would reside in the Routing
Header?
Cheers,
Mo

Subject: RE: Regarding the Options headers
Just one short comment,
I agree with you - but what do you do when the ISP uses this today in their
edge routers?
Lets not make it a religous thing here - this is a real problem that IPv6
are facing when it will take the next step into production networks (with
real speeds) not any field trial networks.
