在这里要要注重一些CLNS的特性，CLNS是独立于IP网络的协议，在FR中Map时不能象以前那样，
map ip XXX.XXX.XXX.XXX DLCI，这样去做了，只要map clns DLCI Bro就可以了。ISIS不在P2MP的环境运行，但是可以在P2P的环境下运行。ISIS不想OSPF有，ip ospf network [类型]命令可以让我们来更改网络类型，所有既要注重CLNS的一些特性。 在出现错误时，常用sh clns nei来查看ISIS的邻居关系有没有建立，deb isis is-nei de来查看ISIS的邻居关系的具体情况，sh isis da来看有没有接受到hello包。
之后可以用sh int s 0命令来查看接口上有没有严重的误码率，来排除是否是物理链路的错误。
