Sergio, The statement below says that the best (longest) match is determined by the IP routing table to be with prefix X. Absent any other information, that is the FEC and resulting label the incoming IP packet maps to. So your LSP follows the same path determined by an IP routing protocol. This isn't a traffic engineering issue. There is no requirement that an FEC should consist of both a source and destination IP address, although it is certainly allowed. In this case, you would use an explicitly-routed or constraint-routed LSP. If you do this, you are free to use a path that does not follow the standard destination-based route. *That* is an example of TE!

After performing a longest-match lookup in its IP routing table, LSR 1 discovers that the best match is with Prefix X and that all traffic matching Prefix X should to be forwarded on Interface 2 with a Label = 10............. How LSR1 discover that the best match is whit that Prefix X?? Does It made same classification based on source address?? Thanks. Sergio |
