Logical_Router_Static_Route TABLE

Each record represents a static route.

When multiple routes match a packet, the longest-prefix match is chosen. For a given prefix length, a dst-ip route is preferred over a src-ip route.

Summary: ip_prefix string policy optional string, either dst-ip or src-ip nexthop string output_port optional string Common Columns: external_ids map of string-string pairs

Details: ip_prefix: string IP prefix of this route (e.g. 192.168.100.0/24).

policy: optional string, either dst-ip or src-ip If it is specified, this setting describes the policy used to make routing decisions. This setting must be one of the following strings:

src-ip: This policy sends the packet to the nexthop when the packet's source IP address matches ip_prefix.

dst-ip: This policy sends the packet to the nexthop when the packet's destination IP address matches ip_prefix.

If not specified, the default is dst-ip.

nexthop: string Nexthop IP address for this route. Nexthop IP address should be the IP address of a connected router port or the IP address of a logical port.

output_port: optional string The name of the Logical_Router_Port via which the packet needs to be sent out. This is optional and when not specified, OVN will automatically figure this out based on the nexthop. When this is specified and there are multiple IP addresses on the router port and none of them are in the same subnet of nexthop, OVN chooses the first IP address as the one via which the nexthop is reachable.

Common Columns:

external_ids: map of string-string pairs See External IDs at the beginning of this document.
