network.routed_bridge

Minimal configlet:

[network#1]
type = routed_bridge

Minimal setup command:

om test/ccfg/foo set --kw="type=routed_bridge"

addr

required:    false
scopable:    true
default:     Detect using a name resolution of `<nodename>`.

Beware, if the nodename resolves to 127.0.1.1 or 127.0.0.1 the ipip tunnel can not work.

The ip address used as local endpoint for the ipip tunnel configured by the network setup command to access the backend subnet of peer nodes not reachable on the same subnet.

gateway

required:    false
scopable:    true

The gateway to use to reach the network segment of the node specified as scope.

ips_per_node

required:    false
scopable:    false
default:     1024
convert:     int

The number of allocatable ips per node on the network.

Converted to the closest power of two.

network

required:    false
scopable:    false

The cluster backend network.

The routed_bridge driver fragments this network into ips_per_nodes blocks subnets.

subnet

required:    false
scopable:    true

The cidr subnet handled by this node.

This parameter must be scoped for each node.

Usually, the subnets are allocated automatically upon initial network setup, each node being attributed a subnet based on its index in the cluster.nodes list.

tables

required:    false
scopable:    false
default:     main
convert:     list

Example:

tables = main custom1 custom2

The list of routing tables to add the backend network routes to.

The list of available tables is in /etc/iproute2/rt_tables.

tunnel

required:    false
scopable:    false
candidates:  auto, always, never
default:     auto

Create and route traffic through tunnels to peer nodes policy.

• auto

  Tunnel if the peer is not in the same subnet

• always

  Tunnel even if the peer seems to be in the same subnet. Some hosting providers require this as traffic goes through routers even between adjacent nodes.

tunnel_mode

required:    false
scopable:    false
candidates:  gre, ipip, ip6ip6
default:     ipip

The ip tunnel mode. gre can tunnel mcast ip and ipv6 at the price of a 24B header, ipip can only tunnel ipv4 but with a 20B header. Note, some OVH servers combinations don't support ipip but work with gre.

type

required:    false
scopable:    false
candidates:  bridge, routed_bridge
default:     bridge

The type of network.
