CCNA 3.10: Configure, verify, and troubleshoot single area and multi-area OSPFv3 for IPv6

Overview:

OSPFv3 has the same functionality as OSPFv2, but uses IPv6 addresses to communicate with OSPFv3 peers.

 

Study Notes:

    • OSPFv3 uses the same SPF algorithm as OSPFv2
    • OSPFv3 has a separate process than OSPFv2
    • OSPFv3 maintains separate neighbor tables, topology tables and routing tables from OSPFv2
    • Similarities
      • Link State
      • SPF algorithm
      • Metric is cost
      • Heirarchical areas
      • Packets exchanged: Hello, DBD, LSR, LSU, LSAck
      • LSDB synchronization
      • DR and BDR election on broadcast multi-access links
      • Use 32-bit router-id and the same process in determining the router-id
    • Differences
      • IPv4 vs IPv6 addresses
      • IPv4 source address vs IPv6 link-local address
      • 224.0.0.5 vs FF02::5 for all OSPF routers
      • 224.0.0.6 vs FF02::6 for DR/BDR election
      • Configured using network command vs ip ospf area command
      • ip routing command on by default vs ipv6 unicast-routing must be configured
