| Property | Description |
|---|---|
| domain-id (Hex | Address) | MPLS-related parameter. Identifies the OSPF domain of the instance. This value is attached to OSPF routes redistributed in BGP as VPNv4 routes as BGP extended community attribute and used when BGP VPNv4 routes are redistributed back to OSPF to determine whether to generate inter-area or AS-external LSA for that route. By default Null domain-id is used, as described in RFC 4577. |
| domain-tag (integer [0..4294967295]) | if set, then used in route redistribution (as route-tag in all external LSAs generated by this router), and in route calculation (all external LSAs having this route tag are ignored). Needed for interoperability with older Cisco systems. By default not set. |
| in-filter (string) | name of the routing filter chain used for incoming prefixes |
| mpls-te-address (string) | the area used for MPLS traffic engineering. TE Opaque LSAs are generated in this area. No more than one OSPF instance can have mpls-te-area configured. |
| mpls-te-area (string) | the area used for MPLS traffic engineering. TE Opaque LSAs are generated in this area. No more than one OSPF instance can have mpls-te-area configured. |
| originate-default (always | if-installed | never; Default: never) | Specifies default route (0.0.0.0/0) distribution method. |
| out-filter-chain (name) | name of the routing filter chain used for outgoing prefixes filtering. Output operates only with "external" routes. |
| out-filter-select (name) | name of the routing filter select chain, used for output selection. Output operates only with "external" routes. |
| redistribute (bgp,connected,copy,dhcp,fantasy,modem,ospf,rip,static,vpn; ) | Enable redistribution of specific route types. |
| router-id (IP | name; Default: main) | OSPF Router ID. Can be set explicitly as an IP address, or as the name of the router-id instance. |
| version (2 | 3; Default: 2) | OSPF version this instance will be running (v2 for IPv4, v3 for IPv6). |
| vrf (name of a routing table; Default: main) | the VRF table this OSPF instance operates on |
| use-dn (yes | no) | Forces to use or ignore DN bit. Useful in some CE PE scenarios to inject intra-area routes into VRF. If a parameter is unset then the DN bit is used according to RFC. Available since v6rc12. |

OSPF protocol supports two types of metrics:
