If a remote IP is specified the udp bearer\nruns in point-to-point mode.\n\nMultiple remoteip addresses can be added via the bearer add  command.  Adding  one  or\nmore unicast remoteip addresses to an existing udp bearer puts the bearer in replicast\nmode  where IP multicast is emulated by sending multiple unicast messages to each con‐\nfigured remoteip.  When a peer sees a TIPC discovery message from an unknown peer  the\npeer  address  is  automatically added to the remoteip (replicast) list, thus only one\nside of a link needs to be manually configured.
