 +===OSPFv2 Notes===
 +  * 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**
 +
 +===Configure OSPFv2===
 +  - The Customer has already enabled OSPF on r2.
 +  - Configure interface link to r2.
 +
 +==Task 1==
 +  * Delete LAN static routes on r1 for both IPv4 and IPv6.
 +  - ++Answer|<code>delete routing-options static route 172.16.40.0/24
 +delete routing-options rib inet6.0 static route 2001:db8:0:40::/64</code> ++
 +
 +==Task 2==
 +  * Create and OSPF neighbor connection to r2.
 +  - ++Answer|<code>set protocols ospf area 0 interface et-0/0/8.0</code> ++
 +  * Verify neighborship.
 +  - ++Answer|<code>show ospf neighbor</code> ++
 +  - ++Answer|<code>show route protocol ospf</code> ++
 +
 +==Task 3==
 +  * Advertise the three LAN prefixes to r2
 +  - ++Answer|Make the three interfaces passive. ++
 +  * Configuration
 +  - ++Answer|<code>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</code> ++
 +  * Verify OSPF route table
 +  - ++Answer|<code>show route protocol ospf table inet.0</code> ++
 +
 +==Task 3==
 +  * Advertise a default route to r2.
 +    * Configure a routing policy to advertise between routing protocols.
 +  - ++Answer|Under Construction ++
 +
 +
 +===OSPFv2 vs. OSPFv3===
 +^  OSPFv2  ^  OSPFv3  ^
 +|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-0/0/0.0**
 +  * **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**
 +  * **show route protocol ospf3**
