Then, if there is a router in the backbone that is not connected to the L1 router , it can be configured as an L2 router .

In the dynamic setup, let the tunnel head end router calculate the path that the TE tunnel can traverse the network to the tail end in an optimal manner. We only need to configure the destination of the tunnel , and then the first-end router uses the CSPF algorithm to calculate the path itself. For prefix-access-list – the IP access list that selects the destinations for which the labels will be PSNP The integrated IS-IS protocol implemented by CISCO was first released during the period 1991/1992 . Since then a series of improvements and extensions have been made. The large-scale development of the IS-IS protocol in major ISP networks began in 1995 , and another important reason was the US government 's interest in ISO CLNS . Although integrated IS-IS has dual routing capabilities,ccna pdf file download, it is interesting to note that most of today's world's largest ISP networks use IS-IS protocols only for IP routing.
