- presenting agenda - No-one to present new HMAC draft - Ran: we will take draft into WG LC? - Chopps: yes. - Les presenting EXTLSP update - version 2 update - resubmit for std track - conflict in metric of tlv22/23 clarifies conflict (i.e.: use tlv22) - Les presenting GENAPP update - WG doc now. - updated for std track - applicability statement (routing vs non-routing info) - possible that we have to re-evaluated applicability compared to existing info carried in isis. - wg to decide which info goes where Chopps Q: any work in parallel with ospf ? Roy A: we presented similar draft in ospf wg chopps: same decisions should be consistent in isis/ospf in terms of what goes where Q: how to decide existing rfc's ? are we going to impose to revise existing rfc's ? inventory base ? screening of existing rfcs ? just asking... Les A: news info is straight forward. for exiting tlv's it will be discussed in wg. no intention to force existing tlv to move. Chopps: moving target. we're not deciding anything now. - Les presenting isis and BFD draft - use of bfd of isis - isis does not share forwarding fate with bfd (ipv4/6 and clns) - prevent isis adj. if bfd is not set. - see presentation slides and draft. - ask for WG document (was it before ?) - Q: what if bfd session takes time more than holdtime ? A: isis session goes down Q: is it good to bring down isis adj ? maybe it's good to bring isis up even if bfd is down and start the state machinery after bfd is up. chopps: if bfd never comes up you will never detect failure Les: we buying some time. should be sufficient to bfd to come up. if not then assumption is that you have forwarding failure Q: concern: impl. support bfd . another router has buggy softw. you bring down adj because of buggy soft. A-chopps: isn't this normal ? you have to pickup a timeout or you don't detect. les: if impl. has problem.... then you have to react to that.... chopps: wg document before. any objection ? no objection, WG doc. - George Swallow on bitvector draft - gather reaction on new idea... - see presentation slides/draft. George Q: feedback /120 v6 assumption. A: I don't think it's a major problem in doing that. Q: what if vector different ? what if abr summarization mask is not same? A: you do what we do today. most specific summary. Bruno Decraene: bgp NHT, does the drat address tunnel mode or hop-by-hop? Stefano rephrases: do you need a tunnel to next-hop or does it work with hopbyhop routing George: routing hop by hop and work well with tunnels. BD: should bgp use the bit vector ? G: bgp registers with isis to find out the next-hop based on bits BD: case of hop by bop. forw. loops if routers not compliant/supporting. SP: yes, but this is deployment issue. Full support is required before enabling it. G: the idea is also targeted for tunneling. Q: instability in one area will trigger generation of bitvector. churn is in routing plane not in fib Kireeti: if point is tunnel ldp vector ? isis is ip reachability. there are other tunnels (IP) but if you put it in isis it's for ip only. nht for ip if isis. - doc status by chopps - require 2 independent implementations - non legacy requires implementation reports. - legacy not requiring implementation reports - see slide on rfc/draft numbers/names - rfcs completed - see slides Tony: mea culpa (3 times) - comments ? Kireeti: gmpls-isis std ? do you want ? A: it has to be because of referenced deployed: Kireeti: not implemented END of Meeting
