有点不太理解。
他说CSPF还要配合RSVP+IGP才能完成MPLS-TE
我觉得CSPF本来就建立LSP了，+IGP就直接可以MPLS-TE了。
不是太理解，大牛们，给解释一下好吗？ |

发帖数: 1055 | 2 You need to get basic concepts right first: 1)IGP LSAs carry bandwidth
information of interfaces, 2)CSPF calculates constrained path to destination
,3)RSVP signals the LSP along the path calculated in 2nd step.
You don't need to be a big-cow to get the basic concepts right, say by
spending one hour googling. |

我还以为IGP先跑好，然后CSPF算好，直接signal好，然后transport label就可以哗哗
哗的跑了。
还要RSVP，好麻烦啊。

LSP都建好了，为什么还要RSVP呢？直接transport layer就通了啊？
