OSPF WG Meeting - Chicago - July 24, 2007 Scribe: Michael Barnes (mjbarnes@cisco.com) 13:22 Review agenda - Acee Lindem 13:25 Review working group progress - Abhay Roy OSPFv3 MTR draft needs more discussion OSPFv2 HMAC-SHA1 draft needs more discussion 13:30 OSPFv3 MIB - Acee presenting slides for Dan Joyal Want to do WG Last Call soon 13:35 Draft Authentication/Confidentiality for OSPFv2- Suresh Melam Acee: A single hop virtual-link packets could have the same src/dst as non-VL packets on the link. Vishwas Manral: SPD is defined by IPSec, but is internal to an implementation so not limited to what RFC specifies. But implementations don't support it. Bill Atwood: Work being presented in routing security WG for automatic rekeying. Work going on in PIM for rekeying to protect link-local addressing. The last slide references the automatic rekeying, it should be linked to the other work. Acee: Straw poll as to whether to make WG document, some support, a couple of folks against. Taking it to the list. 13:54 Extensions to OSPF for Inter-AS TE - Mach Chen Dave Ward: Asking if the working groups feels a new link type is required Acee: Doesn't seem like this is a link Kireeti Kompella: Should just be a TE LSA. Do not have adj or hellos, but want to add into database to do calculations. Dave Ward: Do we need to carry the AS number and what is it used for? Adrian: Can be used for signalling (details lost here) Kireeti: Useful to carry the Router ID, ambivilent about the AS number Dave: Would like to see why, where, when and applicability for carrying the AS number. Router ID is sufficient but necessary. AS number is not necessary Adrian: From CCAMP: close to last calling it. Acee: Seems like this is a connection to an AS as opposed to a link. Do we really want to call it a link, or should be a top level TLV? Two top levels now: Link TLV and Router Address TLV. Mach: ? Acee: So it is tied to the link. Abhay: The link in a TE LSA are additional attributes to the physical link. Kireeti There is a link, it's passive Acee: AS Number is passive information Kireeti: Since no adjacency want full TE info, can't do calculation if don't have A2-B1 link Would like explicit statement saying no hellos and no adjacency. Draft implies that. Do not want an inter-AS adjacency. Abhay: Need a new link type? Kireeti: Could be point to point Dave: Doesn't matter because it's passive Kireeti: Don't think a new type is needed. Mach: Need a new type to indicate that is inter-AS Adrian: Point was that inter-AS TE how careful do you want to be to avoid confusion, A new type avoids any ambiguity. If not worried about ambiguity a new type may not be needed 14:15 OSPF Charter Update - Acee Decided to make an incremental update this time around. Dave W: Solution to separate routing from non-routing information Abhay: Okay to solve in v3 only? Dave: Advise to solve in v2 since it's so widely deployed Convergence is highest priority, so need a way to prioritize routing over non-routing. Acee: Reason? Dave: Protect, preserve fastest possible convergence time. It's something that's been worked on in ISIS for a while now. Acee: Multiple instaces supported by OSPFv3 Dave: Think we need to have a solution for OSPFv2, not sufficient to require changing to OSPFv3.
