Therefore, it will switch to R1-R3-R4-R5 . R3 configuration is as follows (Note that, Area0 and area1 must activate the MPLS the TE ): Take a look at the routing table for R1 : Show ip route isis Or, I let the LDP adjacency between R1-R4 be established,cisco certificate sample, then the OSPF between R1-R4 will naturally come up. Well, we now let the LDP adjacency between R1-R4 , and then the OSPF adjacency will be automatically established. No mpls ip propagate-ttl [ forwarded | local ] Transport addr is generally equal to LDP ID unless it is specified by hand ( mpls ldp discovery transport-address ) . Note that here (described above) there are actually three kinds of addresses: interface IP , Transport addr , LDP ID 0x0000000C IS R3.00 10.1.12.2 Domain-wide Prefix Distribution with Two-Level IS-IS My Address: 10.1.12.1 Mpls traffic-eng tunnels mpls label range 400 499 MPLS relies on IP routing and CEF switching This will directly cause R1 to select the nearest exit from R2 and R3 , and generate a default route to point to this exit. Since this experiment, the cost of R2 , R3, etc. , there are two defaults in R1 's routing table. Route load balancing. This default, automatic mechanism is a benefit for the level1 area because it can reduce the routing table and provide a way to go out, but it also poses a problem, for example, if R2 or R3 is connected to the backbone . If the link DOWN is gone, will R1 still stupidly throw the packet to R2 or R3 ? Fortunately, in the new CISCO IOS , IS-IS is optimized: under normal circumstances, R2 and R3 will flood the 49.0001 area.
