  ---------------------------------
  拓扑如上
  R2、R3、R5之间为FULL MESH的NBMA网络, 区域1, R4、R1组成区域2
  R2: 49.0001.1420.0000.2002.00
  R3: 49.0001.1420.0000.3003.00
  R5: 49.0001.1420.0000.5005.00
  -------------------------------------------------
  R4: 49.0002.1420.0000.4004.00
  R1: 49.0002.1420.0000.1001.00
  
  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。
