ccna 200 301 syllabus of errors democracy.Referring to the configuration in the previous section, from the R1 routing table "D2.0.0.0/8 [90/133120] via21.1.1.2,03:57:33,FastEthernetO/O",You can learn that the IP address of R1's relay to the 2.0.0.0/8 network is 21.1J.2, and the feasible distance is 133120. From R1's topology table, you can also learn that the feasible distance is 133120.The topology table of R1 shows the following.Codes: p ~ Passive, A -Active, U -Update, Q -Query,R -Reply, r-reply Status, s -sia StatusP 1.0.0.0/8, 1successors, FDis 128256 via Summary (128256/0), NullO P 1.1.1.0/24, 1 successors, FDis 128256 via Connected, LoopbackOP 2.0.0.0/8, 1 successors, FDxs 133120 via 21.1.1.2 (133120/128256)z FastEthernet0/0 via 12.1.1.2 (2297856/128256), Seriall/1P 12.0.0.0/8, 1 successors, FDis 2169856 via Summary (2169856/0), NullO P 12.1.1.0/24, 1 successors, FDis 2169856 via Connected, Seriall/1 P 21.0.0.0/ 8, 1 successors, FDis 5120 via Summary (5120/0), NullO P 21.1.1.0/24, 1 successors, FDis 5120 via Connected, FastEthernet0/0. RD (ReportedDistance) or AD (AdvertisedDistance.): the distance to the same destination network as advertised by the next-hop router. RD and AD are just two different names, both refer to the neighboring router's reported distance..FS (Feasible Successor): one reason why DUAL can converge quickly is that it preserves the backup path to the target network, also called FS.When the topology changes, DUAL does not need to recalculate ,
