ccna 200 301 o.(2) R4 clears its OSPFv3 process so that it can start using the new 1.1.1.1 RIDO(3) R4 lists the syslog message, which indicates that the neighbor relationship is invalid (because of the clear command).(4) R4 lists the syslog message, which indicates why R4 cannot now be a neighbor to R1 (1.1.1.1). Example 17-9 Result of R4 changing its RID to the same value as R1, 1.1.1.1R4# configure texminal Enter configuration commands, one per line. end with CNTL/Z. r4(config)# ipv6 router ospf 4 R4(config-rtr)# itouter-id 1.1.1.1 % 0SPFv3: Reload or use "clear ipv6 ospf process" command, for this to take effect R4(config-rtr)# *Z R4# clear ipv6 ospf process Reset ALL OSPF processes?

(Note that these examples also use the same network design as in Figure 17-1 and 17-2. the router typically has one neighbor. the RID that R1J replicated would now prevent R4 and R1 from being neighbors,. Therefore the show ipv6 ospfneighbor command for R4 does not list any output.The next example (Example 17-10) mimics the OSPFv2Hello and dead timer mismatch that appeared in Chapter 11, "Troubleshooting IPv4 Routing Protocols," in the section "Finding OSPFHell. and Dead (Failure) Timer Mismatches. It appeared in the "Finding OSPFHell. and Dead (Failure) Timer Mismatches" section of Chapter 11, "Troubleshooting IPv4 Routing Protocols. Again, according to Figures 17-1 and 17-2, R3's hello and dead timers are 10 and 40, respectively, which are the default values on the Ethernet interface. Before collecting this output, R2 uses the ipv6ospfhello-interval5interface subcommand on interface G0/0 to configure R2's Hello and dead timers to 5 and 20, respectively. (This command sets the Hello timer, and then the IOS sets the dead timer to four times the Hello timer. four times the Hello timer.)Example 17-10 R3 is not in R2's SPFv3 neighbor tableR2# show ipv6 ospf neighbor
