| + | * Route preference = 10 | ||
| + | * Default OSPF Hello messages | ||
| + | * Destination multicast 224.0.0.5 | ||
| + | * Area 0.0.0.0 | ||
| + | * Hello interval = 10 seconds | ||
| + | * Dead interval = 40 seconds | ||
| + | * Passive interfaces advertise the prefix in OSPF, but do not send HELLO messages out of the interface. | ||
| + | |||
| + | ===OSPFv2 Verification Commands=== | ||
| + | * **show ospf neighbor** | ||
| + | * **show route protocol ospf** | ||
| + | * **show route protocol ospf table inet.0** | ||
| + | |||
| + | ===OSPFv2 View Configuration=== | ||
| + | * **show configuration protocols ospf** | ||

| + | ===OSPFv2 vs. OSPFv3=== | ||
| + | ^ OSPFv2 | ||
| + | |Advertises only IPv4|Can only advertise IPv4 or IPv4 and IPv6| | ||
| + | |Configured and verified using **ospf**|Configured and verified using **ospf3**| | ||
| + | ^ Both have ^^ | ||
| + | |Link-state databases|| | ||
| + | |Generate LSAs|| | ||
| + | |Use metric|| | ||
| + | |||
| + | ===OSPFv3 Notes=== | ||
| + | * HELLO messages are sent to ff02::5/128 | ||
| + | |||
| + | ===Configuration for OSPFv3: IPv6=== | ||
| + | * **set protocols ospf area 0 interface et-0/ | ||
| + | * **set protocols ospf area 0 interface et-0/0/8.0 passive** | ||
| + | * **set protocols ospf area 0 interface et-0/0/9.0 passive** | ||
| + | * **set protocols ospf area 0 interface et-0/0/10.0 passive** | ||
| + | |||
| + | ===OSPFv3 View Configuration=== | ||
| + | * **show configuration protocols ospf3** | ||
| + | |||
| + | ===OSPFv3 Verification Commands=== | ||
| + | * **show ospf3 neighbors** | ||
