Ethernet interfaces need to elect DR and BDR,the priority of the interface is lo by default Point-to-point links do not need to elect DR and BDR,the priority of the interface is 0. you can use the ashowip ospf interface,, command on the router to view the priority of the interface. the display for R1 is as follows. 246 Second Chill Chapter - OSPF*** t08 Rl#show ip ospfinterface fa 0/0 FastEthernet0/0 is up,line protocol is up InternetAddress 123.1.1.l/24rArea0 ProcessID 1,RouterID 123.1.1.1,NetworkTypeBROADCAST,Cost:1 Transmit' Delay is 1 sec. stateBDRr Priority1 DesignatedRouter(ID) 123.1.1.2, Interface address 123.1.1.2 Backup Designated router(XD) 123.1.1.1, Interface address 123.1.1.1 Timer intervals configuredrHello10,Dead40, Wait 40, Retransmit5 A lot of information can be found in the above input. The area where the router R1 Fa0/0 interface is located is Area 0, the OSPF process number is 1, and the router RID is 123. The router's RID is 123.1.1.1, the network type is broadcast, and the interface cost is 1. This router's role in this Ethernet segment is BDR, the interface's OSPF priority is 1,the DR for this segment is 123.1.1.2,the Hello interval for this Ethernet interface is 10 seconds and the time to death is 40 seconds. . State: The state of the neighbor router. FULL" means that an adjacency has been established, R3 is DROther, R2 is DR, and this router is BDR. there is no election of DR and BDR on the point-to-point link, "Gas" is displayed.. Dead Time: Show the death time of the neighbor, if the value decreases to 0, the neighbor disappears. The value defaults to 4 times the Hello interval.. Address: IP address of the neighbor's direct connection port.. Interface: The outgoing interface of this router. From the above output, you can see that R1 has 3 neighbors and all of them have established an adjacency relationship. (3) Topology TableThe topology table is also known as the link state database. Look at the topology database on router R1, and it displays as follows: Rl#show ip ospfdatabaseOSPF Router withID (123.1.1.1)(Process ID 1)3 ... n . 3 3 I3.ADV Router Age Seq# Checksum Link count0x80000002 0x004F74 2
