OSPFv3 support only single AF per instance
hi,
refering to
it says, only one address family can be configured per instance
but when I configured it on the router, the IOS did not object !
R1#show run | s router ospf
router ospfv3 1
!
address-family ipv4 unicast
exit-address-family
!
address-family ipv6 unicast
exit-address-family
what is meant then by this statement !?

In there, when they speak about the instance, they refer to the OSPF PID (process ID), and not the the multi-instance OSPF capability. Also, you should know that in OSPFv3 there are NO more network statements, to run OSPFv3 on an interface for IPv4 and/or IPv6 you have to do that at the interface level. So your test is not a valid one, because you just go in OSPF configuration, go in each address-family and do nothing.
If you understand this, it should be clear that what will NOT work, is going at the interface level and run more than one OSPF process per interface, per address-family.Like if you go on an interface and configure this: ospfv3 200 ipv4 area 9 followed by ospfv3 900 ipv4 area 10, you'll only see in show-run the second command, not both of them, becuase this is the restriction.
