Troubleshooting
Troubleshoot OSPFv3 just like OSPFv2. Start by looking at show ipv6
route to verify routes have been advertised. Assuming the route is in the
routing table, test reachability using ping ipv6. You can also look at the
OSPF setup using show ipv6 ospf 1 interface, show ipv6 ospf, or show
ipv6 ospf database.
