CCNA 200-125 Exam: IPv6 OSPF Sim With Answers

Question

All routers run IPv6 OSPF with process ID 100. The IPv4 address of Loopback0 is the OSPF router's ID for each router.

A provider connection is located on the HQ router and you must configure a default IPv6 route in HQ and ensure that this route is announced in the IPv6 OSPF process. Also fix the reason why HQ does not make an IPv6 OSPF neighbor with BR.




Requirement:

1. Configure the default IPv6 route on the HQ router with the default gateway for 2001: DB8: B: B1B2 :: 1
2. After configuring the default router in HQ, point the vendor's IPv6 address 2001: DB8: 0: 1111 :: 1
3. Verify that the default box appears in IPv6 OSPF router HQ. This default route should only be notified if HQ has a default route in the roster table
4. Router HQ does not form an IPv6 OSPF neighbor with BR. Solve the problem and solve it

Special Note: To get the maximum number of points, you must complete the necessary configurations and fix a problem with the IPv6 OSPF interface with the BR BR. IPv6 OSPFv3 must be configured without using address families. Do not change IPv6 OSPF Process ID.

Solution

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

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

First, we need to enable IPv6 routing with the command "ipv6 unicast routing" before we configure a default route on the HQ router.

2. Verify by testing the IPv6 address for the 2001 Provider: DB8: 0: 1111 :: 1, after configuring the default route in HQ:

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

Run the ping test to see if the default pane works. Ping must be successful.
3. Verify that the default box appears in IPv6 OSPF router HQ. This default route should only be notified if HQ has a default route in the schedule table:

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

The "Default Information Origin" command generates a default route, and is sent to all other routers in OSPF domain, provided that the local router has configured a default route.

4. Router HQ does not form an IPv6 OSPF neighbor with BR. Solve the problem and solve it

Perhaps the interface S1 / 0 of HQ not enabled with IPv6 OSPF (check this with the command "show run" or "show ipv6 OSPF interface").

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

After the configuration, use the ipv6 ospf command command in the main directory to see if BR is specified in the output.
