The debug ip ospf packet Command
If you want to view OSPF packet contents of LSAs, use the debug ip ospf packet command:
Router# debug ip ospf packet 4d02h: OSPF: rcv v:2 t:1 l:48 rid:1921681100 aid:0000 chk:15E4 aut:0 auk: from Serial0
Table 20-2 explains the values shown in this command
Field Value
Aid: Auk: Aut: Keyid: L: Rid: Seq: T: V:
Explanation
OSPF Area ID number OSPF authentication key used for neighbor authentication Type of OSPF authentication (0 none, 1 simple password, 2 MD5 hashing) MD5 key value if this authentication mechanism is enabled Length of the packet OSPF router ID Sequence number OSPF packet type (1 hello, 2 data description, 3 link state request, 4 link state update, 5 link state acknowledgment OSPF version number

EXERCISE 20-1 Configuring OSPF
ON THE CD
The last few sections dealt with configuring OSPF on a router This exercise will help you reinforce this material for setting up and troubleshooting OSPF You ll perform this lab using Boson s NetSim simulator You can find a picture of the network diagram for Boson s NetSim simulator in the Introduction of this book In this exercise, you ll set OSPF on the two routers (2600-1 and 2600-2) After starting up the simulator, click the LabNavigator button Next, double-click Exercise 20-1 and then click the Load Lab button This will load the lab configuration based on the exercises in s 11 and 16 1 On the 2600-1, verify that the fa0/0 and s0 interfaces are up If not, bring them up Examine the IP addresses configured on the 2600-1 and look at its routing table At the top of the simulator in the menu bar, click the eRouters icon and choose 2600-1 On the 2600-1, use the show interfaces command to verify your configuration If fa0/0 and s0 are not up, go into the interfaces (fa0/0 and s0) and enable them: configure terminal, interface type port, no shutdown, end, and show interfaces Use the show ip route command You should have two connected networks: 19216810 connected to fa0/0 and 19216820 connected to s0 2 On the 2600-2, verify that the fa0/0 and s0 interfaces are up If not, bring them up Examine the IP addresses configured on the 2600-2 and look at its routing table At the top of the simulator in the menu bar, click the eRouters icon and choose 2600-2 On the 2600-2, verify that the fa0/0 and s0 interfaces are up If not, bring them up: configure terminal, interface type port, no shutdown, end, and show interfaces Use the show interfaces command to verify that the IP addresses you configured on 16 are still there Use the show ip route command You should have two connected networks: 19216830 connected to fa0/0 and 19216820 connected to s0

3 Test connectivity between Host-1 and the 2600-1 At the top of the simulator in the menu bar, click the eStations icon and choose Host1 From Host1, ping the 2600-1: ping 19216811 The ping should be successful 4 Test connectivity between Host-3 and the 2600-2 At the top of the simulator in the menu bar, click the eStations icon and choose Host3 From Host3, ping the 2600-2 router: ping 19216831 The ping should be successful 5 Test connectivity between Host3 and Host1 From Host3, ping Host 1: ping 192168110 The ping should fail: there is no route from the 2600-2 to this destination (look at the 2600-2 s routing table; it doesn t list 19216810/24) 6 Enable OSPF on the 2600-1 router, using a process ID of 1, and put all interfaces in area 0 At the top of the simulator in the menu bar, click the eRouters icon and choose 2600-1 On the 2600-1 router, configure the following: configure terminal, router ospf 1, network 0000 255255255255 area 0, and end 7 Enable OSPF on the 2600-2 router, using a process ID of 1, and put all interfaces in area 0 At the top of the simulator in the menu bar, click the eRouters icon and choose 2600-2 On the 2600-2 router, configure the following: configure terminal, router ospf 1, network 0000 255255255255 area 0, and end 8 On the 2600-2, verify the operation of OSPF Is either router a DR or BDR on the WAN link At the top of the simulator in the menu bar, click the eRouters icon and choose 2600-2 Use the show ip protocols command to make sure that OSPF is configured check for the neighboring router s update Use the show ip route command and look for the remote LAN network number as a OSPF (O) entry in the routing table Use the show ip ospf neighbor command to view your neighboring router Neither should be a DR or BDR on the serial link, since point-to-point connections don t use DRs and BDRs
