I also agree with Sasha. Creating a VCCV type 4 is problematic, almost no hardware exist for it and causes interworking issues. Signaling VCCV needs to change as well.

Using GAL with PWs is highly problematic, and all the related issues (raised during the poll on accepting this draft as a WG item) have not, AFAIK, been resolved.

I was not attending the IETF-79, nor I found discussion of this issue in the minutes. I think that this issue should be specified, explained. In my view, this document updates not only RFC 5586 but RFC 5085 too.

However the problem with vccv is not as simple as to ask for a new code point from IANA. Given the good amount of discussion on this point, we should probably have a discussion in Beijing. Luca On 10/29/2010 05:07 PM, Greg Mirsky wrote: Dear Authors, I think that proposed update of the Section 4.2. RFC 5586 makes it possible to use GAL on MPLS-TP PW that uses Control Word. I consider it to be conflict between PW VCCV CC types because use of GAL is not negotiated through PW VCCV negotiation. To avoid such situation I propose: - in Section 5 request IANA to assign new CC Type "MPLS Generic Associated Channel Label" - assign precedence to new CC Type that affects Section 7 RFC 5085 Regards, Greg _______________________________________________ mpls mailing list mpls@ietf.org<mailto:mpls@ietf.org> https://www.ietf.org/mailman/listinfo/mpls
