IPv6 OSPF Sim

Question

All routers are running IPv6 OSPF with process ID 100. The loopback0 IPv4 address is the OSPF router ID of each router.

On HQ router, a provider link is provided and you have to configure an IPv6 default route on HQ and make sure this route is advertised in IPv6 OSPF process. Also troubleshoot why HQ is not forming IPv6 OSPF neighbor with BR.

Requirements:

1. Configure IPv6 default route on HQ router with default gateway of 2001:DB8:B:B1B2::1
2. Verify by pinging provider test IPv6 address 2001:DB8:0:1111::1 after configuring default route on HQ
3. Make sure that the default route is advertised in IPv6 OSPF router HQ. This default route should be advertised only when HQ has a default route in its routing table
4. Router HQ is not forming IPv6 OSPF neighbor with BR. Troubleshoot and solve the problem

Special Note: To gain the maximum number of points, you must complete the necessary configurations and fix IPv6 OSPF neighbor issue with router BR. IPv6 OSPFv3 must be configured without using address families. Do not change the IPv6 OSPF process ID.

Solution

1. Configure IPv6 default route on HQ router with default gateway of 2001:DB8:B:B1B2::1:

HQ(config)#ipv6 unicast-routing
HQ(config)#ipv6 route ::/0 2001:DB8:B:B1B2::1

First we have to enable IPv6 routing with the “ipv6 unicast-routing” command then we configure a default route on HQ router.

2. Verify by pinging provider test IPv6 address 2001:DB8:0:1111::1 after configuring default route on HQ:

HQ#ping ipv6 2001:DB8:0:1111::1

Issue the ping test to see if the default route works. The ping must be successful.

3. Make sure that the default route is advertised in IPv6 OSPF router HQ. This default route should be advertised only when HQ has a default route in its routing table:

HQ(config)# ipv6 router ospf 100
HQ(config-rtr)#default-information originate

The command “default-information originate” will generate a default route and send to all other routers in the OSPF domain, provided that the local router has a default route configured.

4. Router HQ is not forming IPv6 OSPF neighbor with BR. Troubleshoot and solve the problem

Maybe interface S1/0 of HQ was not enabled with IPv6 OSPF (verify by the “show run” or “show ipv6 ospf interface” command) so we have to enable it.

HQ(config)#interface s1/0
HQ(config-if)#ipv6 ospf 100 area 0

After configuration use the “show ipv6 ospf neighbor” on HQ to see if BR is listed in the output.

    Hi 9tut,

    The IPv6 OSPF simulator does not work for me, it makes me that all the commands are fine, but I cannot ping or show the neighbor relationship. Any ideas. Thank you.

    The very first statement is “All routers are running IPv6 OSPF”. Do show run. See that it is not, in fact, running OSPF at all. Lies.
