  2. History • Changes between netmod-*-00 and netmod-*-01 • Align with draft-ietf-netmod-routing-cfg-13.txt • OSPF WG ospf-yang-00 is in progress • Multiple vendors involved • Dependency on update requested on draft-ietf-netmode-routing-cfg-15.txt • LR vs VRF • Default instance • MT support

  3. Goals • Define OSPF data model that work for multiple vendors • Support various configuration options for different vendors • Support OSPFv2 & OSPFv3 in one model • Support optional features • augment • feature

  4. Configuration Style • Protocol centric router ospf 1 vrf red … router ospf 2 vrf blue … • VRF centric vrf red router ospf 1 … vrf blue router ospf 2 …

  5. Inheritance router ospfv3 201 area 1 stub address-family ipv4 unicast router-id 4.1.1.4 address-family ipv6 unicast router-id 4.1.1.6 address-family ipv4 unicast vrf red router-id 4.1.2.4

  10. Next steps • Submit -00 to OSPF WG • Collaborate with OSPF WG • Is the WG interested to adopt this work as WG doc?
