Thanks for your reply.

It could be a part of specification ( because the problem could occur if the packet size exeeds from the MTU ) but how can you restrict a router in between to not change the IPv6 header.
Thanks Again

PS: Would anyone please refer any RFC or standard document where it is mention that intermediate router can't add any option.

I have two inter-related issues which are unclear to me in RFC 2460. Would

1: If the sending node doesn't include any Hop-by-Hop option header can

=> no, it MUST NOT.
2: If there is Hop-by-Hop option header present can intermediate router add
any new option or modify existing options?
=> it MUST NOT add any new option but it MAY modify an existing option
if the option is marked as mutable en route (there is a bit in the type
to recognize such options) and only in the way defined for this option.
Note there is no such option registered by IANA today so it is hard to
give a real example...

PS: look at the AH specs (RFC 2402 and I-Ds) for mutable fields in headers.
