[00:10:55] <dhruvdhody> Tony: would you lead to loops in TTZ?
[00:11:02] <dhruvdhody> Acee: no that is incorrect
[00:12:16] <dhruvdhody> Hannes: reducing possible network path is not desired like FRR, node protection, but aggregating parts of topology not desirable.
[00:13:12] <dhruvdhody> Hannes: this is relatively easy, but SRLG, TE would become difficult
[00:13:38] <dhruvdhody> Huaimo: There is a draft for TE-TTZ, there as well the changes are manual.
[00:14:31] <dhruvdhody> Acee: This implementation shows that extension is possible, we can look into use-case...this can be a suitable experimental work
[00:15:00] <dhruvdhody> Tony: The problem is interesting. It should be worked on
[00:15:33] <dhruvdhody> 9) OSPF Stub Neighbor - 15 Minutes

[00:25:12] <dhruvdhody> Jon speaking
[00:25:31] <dhruvdhody> Jon: unfortunate name of draft, consider changing names
[00:25:53] <dhruvdhody> Jon: very draft read, not clear what protocol mechanims etc
[00:26:17] <dhruvdhody> (hard)
[00:27:28] <dhruvdhody> when hub receive router lsa of another hub through a spoke?
[00:27:34] <dhruvdhody> what about external routes?
[00:27:53] <dhruvdhody> Author: we would handle in next version
[00:28:20] <dhruvdhody> Shraddha: you have layers of hub and spoke (hierarchy) how do you take care of this
[00:28:39] <dhruvdhody> Faraz: focus on last level
[00:29:45] <dhruvdhody> khaleed: this has specific deployment, this is for pure stub point for morgen stanley
[00:29:55] <dhruvdhody> acee: out of scope
[00:30:37] <dhruvdhody> David: same as running a different routing instance between hub n spoke and apply aggrgation/filtering
[00:30:45] <dhruvdhody> acee: nobody wants to manage that
[00:31:04] <dhruvdhody> for implementation that is a big hammer for apply
[00:31:54] <dhruvdhody> Chairs: Any operator that wants 5000 area? please say now....
[00:32:00] <dhruvdhody> Jon speaking now
[00:32:54] <dhruvdhody> Wenhue: are there any protocol change?
[00:33:41] <dhruvdhody> Faraz: because we are changing default route behavior in hub n spoke scenario
[00:33:51] <dhruvdhody> from RFC2378

[00:40:15] <dhruvdhody> Acee: there is another draft that never gave momentum
[00:40:47] <dhruvdhody> for BGP it is easy to make it go to a specific place, with IGP it goes everywhere
[00:41:44] <dhruvdhody> To operator: is it valuable in ospf vpn for DOS mitigation one hop further, lets discuss on the list...
[00:42:44] Abhay Roy joins the room

[00:57:31] <dhruvdhody> Alia: Is motivation not get IANA?  
[00:58:27] <dhruvdhody> Option 1: Sub-tlv values are all experimental value.  Option 2: FCFS for interacting with iANA
[00:59:22] <dhruvdhody> --Heated discussion--
[00:59:38] <dhruvdhody> just be experimental
[01:00:33] <dhruvdhody> Rob: this could lead to disaster
