[ns] [ns2]address classifier problem

[=?gb2312?q?=CF=E6=BA=CD?=]

Hi:
    The ns2 manual says that addressclassifier is the default classifier for unicast routing (page 45) in wired network. A node in wired network is default a unicast routing node. When I am using gdb to debug my program, I find that the truth is not the same as what the manual says. 
    I find that dstHashclassifier is the default classifier. why ? thanks .
    I want to control the fowarding of each packet a node received, So I modify the addressclassifer class, the manual same it is the entry of a unicast node, and will receive every packet flow over the node, including ones from uplayer or down layer.
   great thanks
