bareudp
Bare UDP tunnels provide a generic L3 encapsulation support for tunnelling different L3 protocols like MPLS, IP etc. inside of an UDP tunnel.
+
+ batadv
+ (B.A.T.M.A.N. Advanced) is a routing protocol for multi-hop mobile ad hoc networks which operates on layer2.

+
+ [BatmanAdvanced] Section Options
+ The [BatmanAdvanced] section only applies for
+ netdevs of kind batadv and accepts the
+ following keys:
+
+
+
+ GatewayMode=
+
+ Takes one of off, server, or client.
+ A batman-adv node can either run in server mode (sharing its internet
+ connection with the mesh) or in client mode (searching for the most suitable internet connection
+ in the mesh) or having the gateway support turned off entirely (which is the default setting).
+
+
+
+
+ Aggregation=
+
+ Takes a boolean value. Enables or disables aggregation of originator messages. Defaults to
+ true.
+
+
+
+
+ BridgeLoopAvoidance=
+
+ Takes a boolean value. Enables or disables avoidance of loops on bridges. Defaults to true.
+
+
+
+
+ DistributedArpTable=
+
+ Takes a boolean value. Enables or disables the distributed ARP table. Defaults to true.
+
+
+
+ Fragmentation=
+
+ Takes a boolean value. Enables or disables fragmentation. Defaults to true.
+
+
+
+ HopPenalty=
+
+ The hop penalty setting allows to modify
+ batctl8
+ preference for multihop routes vs. short routes. This interger value is applied to the
+ TQ (Transmit Quality) of each forwarded OGM (Originator Message), thereby propagating the
+ cost of an extra hop (the packet has to be received and retransmitted which costs airtime).
+ A higher hop penalty will make it more unlikely that other nodes will choose this node as
+ intermediate hop towards any given destination. The default hop penalty of '15' is a reasonable
+ value for most setups and probably does not need to be changed. However, mobile nodes could
+ choose a value of 255 (maximum value) to avoid being chosen as a router by other nodes.
+ The minimum value is 0.
+
+
+
+
+ OriginatorIntervalSec=
+
+ The value specifies the interval in seconds, unless another time unit is specified in which
+ batman-adv floods the network with its protocol information.
+ See systemd.time7
+ for more information.
+
+
+
+ GatewayBandwidthDown=
+
+ If the node is a server, this
+ parameter is used to inform other nodes in the network about
+ this node's internet connection download bandwidth in bits per second. Just enter any number
+ suffixed with K, M, G or T (base 1000) and the batman-adv
+ module will propagate the entered value in the mesh.
+
+
+
+ GatewayBandwidthUp=
+
+ If the node is a server, this
+ parameter is used to inform other nodes in the network about
+ this node's internet connection upload bandwidth in bits per second. Just enter any number
+ suffixed with K, M, G or T (base 1000) and the batman-adv
+ module will propagate the entered value in the mesh.
+
+
+
+ RoutingAlgorithm=
+
+ This can be either batman-v or batman-iv and describes which routing_algo
+ of batctl8 to use. The algorithm
+ cannot be changed after interface creation. Defaults to batman-v.
+
+
+
