  在這里要要注重一些CLNS的特性,CLNS是獨(dú)立于IP網(wǎng)絡(luò)的協(xié)議,在FR中Map時不能象以前那樣,
  map ip XXX.XXX.XXX.XXX DLCI,這樣去做了,只要map clns DLCI Bro就可以了。ISIS不在P2MP的環(huán)境運(yùn)行,但是可以在P2P的環(huán)境下運(yùn)行。ISIS不想OSPF有,ip ospf network [類型]命令可以讓我們來更改網(wǎng)絡(luò)類型,所有既要注重CLNS的一些特性。 在出現(xiàn)錯誤時,常用sh clns nei來查看ISIS的鄰居關(guān)系有沒有建立,deb isis is-nei de來查看ISIS的鄰居關(guān)系的具體情況,sh isis da來看有沒有接受到hello包。
  之后可以用sh int s 0命令來查看接口上有沒有嚴(yán)重的誤碼率,來排除是否是物理鏈路的錯誤。
