  1. IETF 97 Seoul, South Korea Yang Data Model for OSPF Protocol draft-ietf-ospf-yang-06 draft-ietf-ospf-sr-yang-00 Derek Yeung Derek Yeung (derek@arrcus.com) YingZhen Qu (yiqu@cisco.com) Acee Lindem (acee@cisco.com) Jeffrey Zhang (zzhang@juniper.net) Ing-Wher Chen (ichen@kuatrotech.com) 1

  2. Changes since IETF 96 • Update authors information. o Add Acee Lindem and Ing-Wher Chen (Helen) to the drafts. o Update contacts information for both drafts and models. 2

  3. Changes since IETF 96 • Consistent usage of ’enable’ as node identifiers and set default. o Rename candidate-disabled to candidiate-enable and set the default value to TRUE. o Rename node identifiers that end with 'enabled' to 'enable'. o Set the default value of routing/…/ospf/instance/areas/area/interfaces/interface/fast- reroute/lfa/enable (previously named 'enabled') to FALSE. o Set the default value of routing/…/ospf/instance/areas/area/interfaces/interface/fast- reroute/remote-lfa/enable (previously named 'enabled') to FALSE 3

  4. Changes since IETF 96 • OSPF Timers. o Change hello-timer and wait-timer unit to seconds. o Update hello-timer, dead-timer and wait-timer descriptions. o Add 'dead-timer' to routing- state/…/ospf/instance/areas/area/interfaces/interface/neighbors/neighb or. 4

  5. Changes since IETF 96 • Static neighbor ID for IPv4 and IPv6 o Rename ospf/instance/areas/area/interfaces/interface/static- neighbors/neighbor/address to 'identifier' with type inet:ip-address 5

  6. Changes since IETF 96 • Virtual link cleanup. o Remove 'mtu-ignore' and 'prefix-suppression' from virtual-link configuration. 6

  7. Changes since IETF 96 • OSPF interval. o Adjust range specifications from 'transmit-delay', 'dead-interval', and 'retransmit-interval' in routing/…/ospf/instance/areas/area/interfaces/interface. o Change the type of routing/…/ospf/instance/areas/area/interface/interface/dead-interval to uint32 to match RFC2328 Appendix A.3.2. 7

  8. Changes since IETF 96 • New type for bandwidth. o Add IEEE bandwidth type ieee-bandwidth and update all TE bandwidth fields to use it. o Intermediate solution till ietf-routing-types.yang is ready. 8

  9. Changes since IETF 96 • LSA header bit. o Add Nt-bit to OSPFv2 router LSA. o Remove L-bit from OSPFv2 router LSA. 9

  10. Changes since IETF 96 • Fix compilation errors when using Confd. o Fix xpath reference errors to operation-mode and area-type. 10

  11. Changes since IETF 96 • OSPF SR. o Extract OSPF SR into draft-ietf-ospf-sr-yang-00.txt. o Update ietf-ospf-sr.yang to use ietf-segment-routing-common. 11

  12. Current Status • Functionality complete for both config and operation states. • Implementations. 12

  13. Next Steps • Use ietf-routing-types.yang when available. • Ready for last call. 13
