Hello I have a network with 5 hierarchical nodes and 1 mobile-node. 0--------1 | | 2 / \ / \ 3 4 <-5-> I want no change de behaviour of node 1 and node 4 to force a desirable route. I'm trying to make that changes in the recv function in classifier.cc but I can't specify in what node that changes will occur. I don't know how to get in node 1 or 2 because it seems like they don't exist, when look to next_hop it always point to the first or the last node in the hierarchical part (node 0 or 3/4). How could I know in what node I'm really working? Thanks in advance, André Campos
