Hi guys Regarding Lab 3 in Workbook II:
Task 3.2 states: "Configure MD5 authentication for the link between R7 and R8 with password cisco". The Solution Guide provides the correct solution, but has an additional comment which I do not understand - "Verify with show ip ospf interface. Look carefully at the last few lines. Key ID is 0, which is a null key". -------------------------------------------------------------------- R8# show ip ospf int Serial0/0/0 is up, line protocol is up Internet address 110.99.78.8/24, Area 100 Process ID 1, Router ID 110.99.8.8, Network Type POINT_TO_POINT, Cost: 64 Enabled by interface config, including secondary ip addresses Transmit Delay is 1 sec, State POINT_TO_POINT, Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5 oob-resync timeout 40 Hello due in 00:00:02 Supports link-local signalling (LLS) Index 1/1, flood queue length 0 Next 0x0(0) / 0x0(0) Last flood scan length is 1, maximum is 1 Last flood scan time is 0 msec, maximum is 0 msec Neighbor Count is 1, Adjacent neighbor count is 1 Adjacent with neighbor 110.99.7.7 Suppress hello for 0 neighbor(s) Message digest authentication enabled Youngest key id is 1 R8# R8# -------------------------------------------------------------------- The Key ID in the output is 1, in fact, it is not possible to configure a key ID of 0 with MD5 authentication: R7(config-if)#ip ospf message-digest-key ? <1-255> Key ID So what is the solution guide referring to here? Is it a typo, or is my puny brain missing something? What is a "null key" in this scenario? One more thing - the "Initial Config" of R9 is really the "Final Config". It has the MLPPP with multicast routing and everything. Can you please correct this, and update the downloadable fileset to include the correct Initial Config for R9. Thanks...
