Flavors ​

Default flavor ​

Packages list ​

The LibreMesh default flavor contains these packages:

  • babeld-auto-gw-mode
  • batctl-default
  • check-date-http
  • lime-app
  • lime-debug
  • lime-docs
  • lime-docs-minimal
  • lime-hwd-ground-routing
  • lime-hwd-openwrt-wan
  • lime-proto-anygw
  • lime-proto-babeld
  • lime-proto-batadv
  • shared-state
  • shared-state-babeld_hosts
  • shared-state-bat_hosts
  • shared-state-nodes_and_links

Configuration ​

WAN port ​

Configure as WAN Configure default protocols on top of it:

  • babeld:17 - creates a 8021ad soft vlan number 17 and run babel on it
  • batadv:%N1 - creates a 8021ad soft vlan number %N1 and add it to list of batman-adv interfaces

This creates 3 interfaces:

  • wan@eth0 - dhcp client
  • wan_17@eth0 - babeld vlan 17 8021ad
  • wan_29@eth0 - babeld vlan 29 8021ad

LAN ports ​

Add each lan port to the main bridge br-lan
Configure default protocols on top of each port:

  • babeld:17 - creates a 8021ad soft vlan number 17 and run babel on it
  • batadv:%N1 - creates a 8021ad soft vlan number %N1 and add it to list of batman-adv interfaces

Configure the br-lan with network options:

  • main_ipv4_address
  • main_ipv6_address

Creates 3 interfaces for each lan port:

  • lan@eth1 - raw device unmanaged: untagged packets will go to the interface br-lan
  • lan_17@eth1 - babeld vlan 17 8021ad
  • lan_29@eth1 - babeld vlan 29 8021ad

Radios 2ghz and 5ghz ​

Configure default modes ieee80211s, ap, apname

Configure default protocols on top of each port:

  • babeld:17 - creates a 8021ad soft vlan number 17 and run babel on it
  • batadv:%N1 - creates a 8021ad soft vlan number %N1 and add it to list of batman-adv interfaces

Anygw ​

The bridge br-lan includes ethernet lan ports as well as radio interfaces configured as Access Point (ap or apname mode)

On top of br-lan it is configured a mac-vlan interface with for the anygateway feature.
The MAC/ipv4/ipv6 addresses of this interface are the same for all nodes with that share the same lime-autogen.wifi.ap_ssid

Shared State ​

a Conflict-Free Replicated Data Type (CRDT) daemon.
This module enables seamless information exchange between nodes in a decentralized network, ensuring consistency and reliability.

Files are not persisted by default in flash, they can be seen in /tmp/shared-state/data/ The information shared by default depends from shared-state's publishers installed.

  • shared-state-babeld_hosts - babeld connected nodes
  • shared-state-bat_hosts - batadv connected nodes
  • shared-state-nodes_and_links

Mini flavor ​

Packages list ​

The LibreMesh mini flavor contains these packages:

  • babeld-auto-gw-mode
  • check-date-http
  • lime-docs-minimal
  • lime-hwd-openwrt-wan
  • lime-proto-anygw
  • lime-proto-babeld
  • lime-proto-batadv
  • shared-state
  • shared-state-babeld_hosts

Configuration ​

The configuration is the same as the one of the default flavor. The removed packages are:

  • batctl-default - CLI utility to manage batman-adv interfaces with debug commands, in absence batctl-tiny is installed
  • lime-app - the web interface
  • lime-docs - offline docs
  • lime-debug - set of debug tools including tcpdump, mtr, iperf3
  • shared-state-async - newer shared-state in C++
  • lime-hwd-ground-routing - to manage ground routing connections
