Therefore, the router will not BGP direct distribution label route, but for BGP routes by next hop routing label distribution after the recursion, this is very good. BGP routing entry is pretty much, by this way we MPLS , can greatly simplify the performance loss routers, BGP 's Transit AS routing black hole problem has been solved. *Aug 18 04:37:06.243: FLOWSPEC type 2 length 36: When there is a problem with the path of R1-R2-R5 , for example , the link between R2-R5 is DOWN , then the TE tunnel will switch to the path-option of the next priority , that is, the dynamic setting mode. Therefore, it will switch to R1-R3-R4-R5 . Level2 area 0x8000001A 0x002ED2 0 Fa0/0 Create a TE tunnel on R1 , the path is R1-R2-R4-R5 , and create another backup tunnel path as R1-R2-R3-R4-R5 . This path is used as the backup tunnel of the former . *Aug 18 09:06:02.699: 5.5.5.5 (Strict IPv4 Prefix, 8 bytes, /32) Fspec: ave rate=0 kbits, burst=1000 bytes, peak rate=0 kbits R1 Error metric Note: a L1 / L2 router if the other area router adjacency relationship,best braindump site, it will to this area of the L1 router advertisement himself outlet, the specific method is the raw cost region L1 LSP when packets ATT bit Set 1 Fast Reroute Routing information diffusion and database synchronization Regional prefix replacement. As shown above, you want to replace the original area prefix 49.0001 with 49.0002 . To achieve this goal, configure an NSAP address for the new area prefix on A and B. Note that the SystemIDs of the two addresses must be the same. Then delete the areas of A and B in turn . Link ID:: 1 Type The LSR route may receive multiple labels of a specific prefix ( distributed by multiple LDP neighbors), but he only needs to use one of them. The IP routing table is used to determine the next hop of the IPv4 prefix ( the construction of the LFIB needs one). IGP routing table, because the next hop of LFIB is calculated from the IGP table). The LSR uses this information to create its LFIB . The label bundled locally in the LFIB is used as an inbound label, and the label advertised by the LDP neighbor is used as an outbound label.
