Routing

The routing setting contains a dictionary to configure routes and PBR¹ rules:

routes - routes (ip route)
rules - PBR¹ rules (ip rule)

routing:
  # route settings (ip route)
  routes:
    - to: 0.0.0.0/0
      via: 192.0.2.1

# rule settings (ip rule)
  rules:
    - priority: 42
      iif: eno1
      to: 1.1.1.1/32
      action: prohibit

Examples:

Multipath Routing

It is possible to configure multipath routes using the multipath attribute:

routing:
  routes:
    - to: 0.0.0.0/0
      multipath:
        # gateway with default weight (hops: 0)
        - via: 192.0.2.1
        # gateway with increased weight
        - via: 192.0.2.2
          hops: 1

Address Family of the Nexthop Router

It is possible to specify an IP address for the nexthop from another address family. The Linux kernel will use the NLRI¹ to route packets appropriate.

routing:
  routes:
    - to: 0.0.0.0/0
      via: fe80::defa
      dev: eth0
