"O3.3.3.3 [110/2] via123.1.1.3,00:26:35,FastEthemetO/Ow,where the representation is OSPF,the route was learned through OSPF. From the parent route "3.0.0.0/32",we know that R1 learned the route 3.333/32,which is a 32-bit host route. In OSPF, all loopback interfaces are automatically declared as 32-bit host routes, and the actual subnet mask of the interface is ignored. If you want to display the true subnet mask of the loopback interface, you can use the following command under the loopback interface.R3 (config)#int l:o0 R3(config-if)#ip ospf networkpoint-to-point[110/2] Here 110 is the administrative distance of OSPF and 2 is the OSPF metric. "via 123.1.1.3" is the IP address of the next hop of the route, "00:26:35" is the time when the route exists, and "FastEthemet0/0" is the outgoing interface. One difference from the RIPv2 and EIGRP protocols is that OSPF does not support automatic summarization. OSPF supports manual summarization, which is performed on the boundaries of the area, but the CCNA only covers single-area OSPF configurations, so manual summarization is not discussed.The reason that R1 cannot learn the route for the R3 Loopback 1 interface is because R3 does not announce the interface. (2) Neighbor TableViewing the neighbor table on router R1 shows the following (the reader may see results different from those shown here, where the results are obtained by first configuring R2's OSPF, then R1's OSPF, and finally R3's OSPF).Neighbor ID PriState DeadTimeAddress 33.3.3.3 1 FULL/DROTHER 00:00:34 123.1.1.3 FastEthernet0/0 123.1.1.2 1 FULL/DR 00:00:39 123.1.1.2 FastEthernetO/0 123.1.1.2Rl#show ip ospf neighbor. NeighborID: refers to the Router ID of the neighboring routero From the output here, you can see that R3's RID is 33.333,R2's RID is 123.1.1.2.R1 and R2 have established a neighbor relationship twice through different interfaces.
