Summary: this document is ready with minor issues



Major issues:



None



Minor issues:


1.       Section 3 includes the following text:

   When the PW CW is not used, the Type 4 MPLS VCCV Control Channel (CC)
   type defined in this section MAY be used.  This is referred to as
   VCCV CC Type4 throughout the rest of this of this document.  VCCV
   Type 4 uses the encapsulation shown in Figure 1 in which the presence
   of a GAL at the end of the MPLS label stack indicates that the packet
   carries a VCCV message.

Two issues here:

-          Line 3 includes a disturbing typo as the type is referred to in the rest of the document as 'VCCV CC Type 4' (with a space)

-          I understand the MAY in the second line to be directed to the implementers and this is fine. However, what about the operators who own network devices that have implemented this option? From reading the first section I indirectly get that the operators SHOULD activate this option. Maybe a separate paragraph can include this recommendation.


2.       Manageability Considerations - is there a requirement for all devices in a given network to activate the new type support, or a mix of routers supporting and not-supporting this option does not cause a problem?

3.       Section 9.1 - I assume that at publication Bit X (0x0Y) is supposed to be changed to Bit 3 (0x08)

Dan
