Re: Teredo spec has been published!

Hi Bora,

 

I think every AS which has Teredo users should announce Teredo prefix via eBGP.

Only by this way an IPv6 node can find the closest path to a Teredo client.

 

Within the domain, the eBGP router can use other routing protocol to ensure the traffic destinated to Teredo client can reach Teredo relay router.

I think it would be bad if the Teredo prefix was announced via eBGP.
Each domain is supposed to announce
the Teredo prefix within the domain, not outside, if I understood it
correctly. I would also expect
each AS to filter out the announced prefix.

       This problem, for example,
       1. Based on current Teredo spec, the core router in an IPv6
network shall advertise 2001:0000::/32 route through BGP4+ to other
ASes, to ensure the connectivity of its own Teredo users. Also, I think
it's better for the core router to also act as a Teredo relay router,
otherwise too many static routes have to be configured. But how can  we
expect the IPv6 core router to have the native IPv4 connection?
