Re: [v6ops] new draft: draft-taylor-v6ops-fragdrop

[Joe Touch <[e-mail]>]

Hi, all,

As per my recent post, the claim that "we cannot parse the entire IP 
option chain at line rate" doesn't fit with "so we should drop IP 
fragments", since the fragment option need not appear at the head of the 
option chain.

I'm wondering whether routers that drop fragments do so only when that's 
the first option, or do they just drop packets with *any* options?

If just fragments, a quick fix might be to create a new null HBH option 
that is silently ignored, solely to bury the fragment option away from 
the primary IPv6 next-header field.

Can anyone with such a router comment as to what might happen?

Thanks,

Joe
