Rate this post

Visual Topology

Command Line

Command Description
ipv6 ospf process id area id Enables OSPFv3 on the interface
ipv6 router ospf process id Enters OSPFv3 router configuration mode
Ping address Checks end to end connectivity
router-id 32bit id Assigns a 32 bit router-id in a dotted decimal format, example (1.1.1.1)
show ipv6 ospf Displays OSPFv3 settings
show ipv6 ospf neighbor Displays the contents of the OSPF adjacency table
show ipv6 route Display the contents of the IPv6 routing table.

Task 1: Enable OSPFv3.

Step 1: Access the CLI of the router and check that you still have the IPv6 addresses configured on your router, if not, rectify.

Step 2: Ping the IPv6 address of the other routers fa0/1 or gi0/1 interface. If you have correctly configured both end of the directly connected link, then this should be successful.

Step 3: Ping the IPv6 address located on the other router, this should fail because it is not directly connected and just like in IPv4 no dynamic routing protocols are enabled by default to advertise it out.

Step 4: Enter OSPFv3 configuration mode and assign the following router ID’s

R1 only.....
Router ID 1.1.1.1
R2 only.....
Router ID 2.2.2.2

Do you need to configure unique router ID’s ?

Step 5: Enter the configuration mode for the interface directly connecting the two routers together, fa0/1 or gi0/1.

Step 6: Enable OSPFv3 on the interface and check you have an OSPF adjacency.

Step 7: Try pinging the loopback IPv6 address of the other router

Why would it fail?

Step 8: Enable OSPFv3 on the loopback interface and ask the other student to try and ping it, because you are now advertising it via OSPFv3 this should work.
