Yimin,

I think these IPv6 encodings should be defined (like RFC 6829 did for example) instead of saying “they are not in RFC 4447”. But, specifically, where in RFC 4447?

Thanks,

Hi Suresh,

Thanks very much for your review and the question about section 6.4.1 and 6.4.2.

This document does not define any new encoding. Instead it is using the definitions of RFC4447, as noted in 6.4 for intro to 6.4.1 and 6.4.2. Specifically, the “Protection FEC Element TLV” uses the encoding and semantics of PWid FEC and Genercalize PWid FEC defined in RFC 4447. These FECs carry IPv4 addresses, and there is currently no IPv6 encoding defined for these FECs by IETF.

Hope this clarifies it for you.

Thanks,

-- Yimin

   Sections 6.4.1 and 6.4.2

   The Ingress and Egress PE Addresses are encoded as 4 byte fields. How is
   this expected to work with IPv6 addresses for the PEs?
