Method of establishing a route between a Route Originator, RO, mesh node and a Route Destination, RD, mesh node in a mesh network, said mesh network comprising a plurality of mesh nodes, said method comprising the steps of: - assembling, by said RO mesh node, a Route Request, RREQ, message, wherein said RREQ message is related to said route between said RO mesh node and said RD mesh node, wherein said step of assembling comprises: - introducing, in said RREQ message, an address of said RO mesh node and an address of said RD mesh node, - retrieving a Route Sequence Number, RSN, from a Route Sequence Number Table, RSNT, said RSNT being comprised by said RO mesh node and used for maintaining a plurality of entries each directed to a specific pair of RO mesh node and RD mesh node and an RSN related thereto, said RSN being incrementable or decrementable per said pair of said RO mesh node and said RD mesh node instead of per said RO mesh node, - updating said retrieved RSN, by incrementing said retrieved RSN or decrementing said retrieved RSN, and introducing said updated RSN into said RREQ message; - broadcasting, by said RO mesh node, said assembled RREQ message in said mesh network; - receiving, by said RD mesh node, via any of said plurality of mesh nodes, said RREQ message; - determining, by said RD mesh node, that said RREQ message is to be taken into account; - transmitting, by said RD mesh node, in reply to said received RREQ message and to said determination that said RREQ message is to be taken into account, a Route Reply, RREP, message towards said RO mesh node, via said mesh network; - receiving, by said RO mesh node, via any of said plurality of mesh nodes, said RREP message thereby establishing said route between said RO mesh node and said RD mesh node. - assembling, by said RO mesh node, a Route Request, RREQ, message, wherein said RREQ message is related to said route between said RO mesh node and said RD mesh node, wherein said step of assembling comprises: - introducing, in said RREQ message, an address of said RO mesh node and an address of said RD mesh node, - retrieving a Route Sequence Number, RSN, from a Route Sequence Number Table, RSNT, said RSNT being comprised by said RO mesh node and used for maintaining a plurality of entries each directed to a specific pair of RO mesh node and RD mesh node and an RSN related thereto, said RSN being incrementable or decrementable per said pair of said RO mesh node and said RD mesh node instead of per said RO mesh node, - updating said retrieved RSN, by incrementing said retrieved RSN or decrementing said retrieved RSN, and introducing said updated RSN into said RREQ message; - introducing, in said RREQ message, an address of said RO mesh node and an address of said RD mesh node, - retrieving a Route Sequence Number, RSN, from a Route Sequence Number Table, RSNT, said RSNT being comprised by said RO mesh node and used for maintaining a plurality of entries each directed to a specific pair of RO mesh node and RD mesh node and an RSN related thereto, said RSN being incrementable or decrementable per said pair of said RO mesh node and said RD mesh node instead of per said RO mesh node, - updating said retrieved RSN, by incrementing said retrieved RSN or decrementing said retrieved RSN, and introducing said updated RSN into said RREQ message; - broadcasting, by said RO mesh node, said assembled RREQ message in said mesh network; - receiving, by said RD mesh node, via any of said plurality of mesh nodes, said RREQ message; - determining, by said RD mesh node, that said RREQ message is to be taken into account; - transmitting, by said RD mesh node, in reply to said received RREQ message and to said determination that said RREQ message is to be taken into account, a Route Reply, RREP, message towards said RO mesh node, via said mesh network; - receiving, by said RO mesh node, via any of said plurality of mesh nodes, said RREP message thereby establishing said route between said RO mesh node and said RD mesh node.
