TroubleShooting OSPFv3 Address Familes Configuration

                          With the OSPFv3 Address Families Configuration we can have one hierarchical Configuration that contains our OSPF Configurations for both IPv4 and IPv6 Routing and there gonna be a single database maintain, we can give a single command and we can get information about both IPv4 and IPv6 and along with address Families, we got a new set of commands we can use for Verification and Troubleshooting and the great news is we can still use older commands we can still say for example
v  R1#show ipv6 ospf neighbor
                      Just using addressing family doesn’t mean that older command don’t work but now we have got new set of commands we could say
v  R2#show ospfv3 neighbor
               And notice this gives us information about our different Address Families one for IPv4, one for IPv6 before we look into more on these commands though i want to show you and remind you what the Address Family Configuration looks like, let’s do a
v  R2#show run | s router ospfv3
                We have got this one hierarchical Configuration structure
Router OSPFv3 and process ID of 1
And notice we have got two Address Families, one for IPv4 unicast, One for IPv6 unicast and it’s under these Address Families where we can configure the various OSPF parameter that we might want to tweak for example, i said that Area 1 is gonna be a STUB area but that’s only for IPv6 now let’s take a look at some more commands, we can use to get information from this combined database, similar to the
v  R2#show ipv6 ospf
Now we got a
v  R2#show ospfv3
That’s gonna give us similar information and there is not a replacement for the
v  R2#show ip protocols
v  R2#show ipv6 protocols
That’s not a replacement for that we can still use those if we want now let’s take a look at our interfaces that can say
v  R2#show ospv3 interface brief
                  And we can see for the different Address Families IPv4 and IPv6, we can see what interface is participating in specific ospf Areas but notice we all using the same Process ID of 1 its all into a single hierarchical configuration if we want to get more information about a specific interface, we can do that
v  R2#show ospfv3 interface f0/0
Ø  And we get thing like Timer Information
Ø  Router ID information
Ø  OSPF network type information, to look at our neighbors we can say
If we wanna look at Link State database, we can say
v  R2#show ospfv3 database
               And we first get to see the Link State database for the IPv4 Address Family and after scrolling down

                 We can see the IPv6 Address Families with all of its LSA’s and that the quick look of handful show command, we can use when Verifying and Troubleshooting OSPFv3 using to Address Families Configuration
