The following will be analyzed separately: Type : 0x8847 (unicast) upper layer carries MPLS , find LFIB 3.3.3.3 The link state database of TEDB and IGP is independent. Distribution mode (the Label Distribution's) : the downstream drive mode (Downstream Unsolicited) Define source Mpls traffic-eng router-id loopback0 To add: In the above environment, the loopback interface cost=1 , and the cost of all other physical interfaces =10 . Then if we configure: Test 2 : SET-overload-ON-Startup 'bit the wait-for-BGP Mpls traffic-eng tunnels ip rsvp bandwidth Type escape sequence to abort. Certification Information Ip address 10.1.34.3 255.255.255.0 Router ospf 1 Bytes tag switched Mpls traffic-eng tunnels ip rsvp bandwidth Ip address 5.5.5.5 255.255.255.255 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,ccna exam multiple choice, R2 and R3 will flood the 49.0001 area.
