What level do we usually use for a PHd student? -----Original Message----- From: Mailing List [mailto:OSPF@PEACH.EASE.LSOFT.COM]On Behalf Of Adrian Farrel Sent: Monday, May 23, 2005 6:33 AM To: OSPF@PEACH.EASE.LSOFT.COM Subject: Re: Working Group Last Call for "Traffic Engineering Extensions to OSPF version 3" Hi, Two comments... 1. Would it be possible to clarify the behavior if the scope is set to some value other than 01? Is it a requirement that the scope be ignored in that case, that TE information be allowed to be flooded out of the area, or that the LSA is rejected? Given the setting of the U-bit, this may be hard to control properly and I suspect the best you can do is say MUST be transmitted as 01 and SHOULD only be flooded within the area. 2. Section 4 - Router IPv6 Address TLV "The Router IPv6 Address TLV has type 3, length 16, and a value containing a 16 octet local IPv6 address. It MUST appear in exactly one Traffic Engineering LSA originated by an OSPFv3 router supporting the TE extensions." I am confused by 'MUST appear in exactly one'. Can a router advertise multiple Router addresses? (Hint, please talk to the CCAMP ASON Routing design team for a very good reason why the answer is "yes".) Can a TE LSA contain "orphaned" TLVs? I.e. can we have a continuation TE LSA that does not carry a Router Address TLV? Given that a router has (probably) more than one "stable IPv6 address that is always reachable if there is connectivity to the OSPFv3 router" must all of these be advertised in Router Address TLVs? The text needs to cover all of these questions. Cheers, Adrian
