     OPTIONS
          Options (flags) that can be passed anywhere in the command
          chain.

          -h, --help
               Show help about last valid command. For example tipc
               bearer --help will show bearer help and tipc --help
               will show general help. The position of the option in
               the string is irrelevant.

     DESCRIPTION
        Bearer identification
          media MEDIA
               Specifies the TIPC media type for a particular bearer
               to operate on.  Different media types have different
               ways of identifying a unique bearer.  For example, ib
               and eth identify a bearer with a DEVICE while udp iden-
               tify a bearer with a LOCALIP and a NAME

               ib - Infiniband

               eth - Ethernet

               udp - User Datagram Protocol (UDP)

          name NAME
               Logical bearer identifier valid for bearers on udp
               media.

          device DEVICE
               Physical bearer device valid for bearers on eth and ib
               media.

        Bearer properties
          domain
               The addressing domain (region) in which a bearer will
               establish links and accept link establish requests.

          priority
               Default link priority inherited by all links subse-
               quently established over a bearer. A single bearer can
               only host one link to a particular node. This means the
               default link priority for a bearer typically affects
               which bearer to use when communicating with a particu-
               lar node in an multi bearer setup. For more info about
               link priority see tipc-link(8)

          tolerance
               Default link tolerance inherited by all links subse-
               quently established over a bearer. For more info about
               link tolerance see tipc-link(8)

          window
               Default link window inherited by all links subsequently
               established over a bearer. For more info about the link
               window size see tipc-link(8)

        UDP bearer options
          localip LOCALIP
               Specify a local IP v4/v6 address for a udp bearer.

          localport LOCALPORT

     TIPC-BEARER(8)            (02 Jun 2015)            TIPC-BEARER(8)

               Specify the local port for a udp bearer. The default
               port 6118 is used if no port is specified.

          remoteip REMOTEIP
               Specify a remote IP for a udp bearer. If no remote IP
               is specified a udp bearer runs in multicast mode and
               tries to auto-discover its neighbours.  The multicast
               IP address is generated based on the TIPC network ID.
               If a remote IP is specified the udp bearer runs in
               point-to-point mode.

               Multiple remoteip addresses can be added via the bearer
               add command. Adding one or more unicast remoteip
               addresses to an existing udp bearer puts the bearer in
               replicast mode where IP multicast is emulated by send-
               ing multiple unicast messages to each configured
               remoteip. When a peer sees a TIPC discovery message
               from an unknown peer the peer address is automatically
               added to the remoteip (replicast) list, thus only one
               side of a link needs to be manually configured. A
               remoteip address cannot be added to a multicast bearer.

          remoteport REMOTEPORT
               Specify the remote port for a udp bearer. The default
               port 6118 is used if no port is specified.

     EXIT STATUS
          Exit status is 0 if command was successful or a positive
          integer upon failure.
