OSPF WG Minutes - Wednesday March 25th, 2009 Scribe: Russ White (russ@cisco.com), Edited by Acee Lindem (acee@redback.com) Document Status - Acee Lindem - See Slides Notable Comments: OSPFv3 MIB in last stages. Will have short WG last call on a diff MIB doctor update. OSPF TE Node Address will be WG last called shortly after IETF. HMAC-SHA1 under discussion. Dave Ward - Please address my comments on both the dynamic hostname and multiple address family drafts. Acee - Will do - we need to be careful as not to overly restrict the instance ID space since it is very small (8 bits). OSPF Extensions in support of WSON - Greg Bernstein - See Slides Notable Comments: Greg Bernstein - These extensions are used for provisioning optical networks - not IP networks. Dimitri Papadimitriou - There could be a problem with nodes with interfaces in multiple areas. Greg - May need new top-level TLVs. The optical connectivity matrix will change more frequently than the rest of the information. Dimitri Papadimitriou - Need to determine correct TE LSAs for new TLVs. Acee - Suggest everybody review. Jonathan Sadler - There seems to be potential applicability to things outside wavelength switched environments, or a way of adding TE and other options on older equipment, etc, in the realm of TE. Acee - This is a problem for CCAMP. Dimitri Papadimitriou: Need to determine correct TE LSAs for new TLVs. Dimitri or Jonathan - Will the TLVs for optical exceed 64K bytes? Greg: Doesn't expect this to happen in the next 20 years. LDP-IGP Sync on Broadcast Networks - Sri Kini - See Slides - MPLS Draft _ Compatible with RFC 5443 Notable Comments: Question: How is a cut-edge determined? Sri Kini - During SPF, it is a cut-edge path if it is the only path to the broadcast network. Acee - What happens if not all routers on broadcast network support this draft? Sri - It is fully compatiable. Only routers supporting the draft will delay advertisement until LDP sync is complete. Question: Why should this be standardized? Acee: Even though the bits on the wire don't change, this is a protocol change since the behavior changes. OSPF Sparse Topologies - Acee Lindem - See Slides Notable Comments: Jonathan - Please restrict the transport information to non-routing information. It could be non-IP routing information such as GMPLS, optical, etc. OSPF Charter - Abhay Roy - See Slides Abhay - Summary: Although we are late on some items, we are progressing many of the long standing documents. We will accept new work but there must be a requirement and commitment to work on it. Notable Comments on HMAC-SHAx: Tony Li: Use of Apad in HMAC-SHAx doesn't make the algorithm stronger. It satisfies the primary customers consistency requirement with neglible overhead. Ran Atkinson: The DoD really does want Apad to be included in the HMAC-SHAx computation.
