Hi, As far as I remember, you can not have 2 links between 2 nodes because there is a global array for all the links ("links_" was the name?) Furthermore, you can't have 2 nodes connected to 2 LANs (because a LAN is implemented as a mesh of point-to-point links) Athina. > > Hi,dear all: > > What can I do if there are two links between two nodes? > thanks. > >
