Topology

Notice!
IPv6 addresses have changed. Follow the below topology diagram and tasks to accomplish the goals.

Pic1. IPv6 Topology Diagram.

Task 1
Configure IPv6 addresses on Serial1/0 of R2 and R3. Use router's number as the IPv6 Host ID and Network ID as per topology diagram.

Task 2
Enable OSPFv3 between R2 and R3 using their point-to-point link. Use Area 13.

Task 3
In R2 Create four loopback interfaces with the following IPv6 addresses:

  • Loopback1: FC00:1:1:22:8000::1/80
  • Loopback2: FC00:1:1:22:9000::1/80
  • Loopback3: FC00:1:1:22:A000::1/80
  • Loopback4: FC00:1:1:22:B000::1/80
Task 4
Enable OSPFv3 Area 13 on the above loopbacks. Ensure that the rest of OSPFv3 domain receive a summary route representing all the loopbacks advertised into OSPF in task 3.

Solution

Task 1
Configure IPv6 addresses on Serial1/0 of R2 and R3. Use router's number as the IPv6 host ID and Network ID as per topology diagram.

R2 Config:
!
interface Serial1/0
 ipv6 address FC00:1:1:20::2/64
!

R3 Config:
!
interface Serial1/0
 ipv6 address FC00:1:1:20::3/64
!

Task 2
Enable OSPFv3 between R2 and R3 using their point-to-point link. Use Area 13.

R2, R3 Config:
!
interface Serial1/0
 ipv6 ospf 1 area 13
!

Task 3
In R2 Create four loopback interfaces with the following IPv6 addresses:
  • Loopback1: FC00:1:1:22:8000::1/80
  • Loopback2: FC00:1:1:22:9000::1/80
  • Loopback3: FC00:1:1:22:A000::1/80
  • Loopback4: FC00:1:1:22:B000::1/80
R2 Config:
!
interface Loopback1
 no ip address
 ipv6 address FC00:1:1:22:8000::1/80
 ipv6 ospf network point-to-point
!
interface Loopback2
 no ip address
 ipv6 address FC00:1:1:22:9000::1/80
 ipv6 ospf network point-to-point
!         
interface Loopback3
 no ip address
 ipv6 address FC00:1:1:22:A000::1/80
 ipv6 ospf network point-to-point
!         
interface Loopback4
 no ip address
 ipv6 address FC00:1:1:22:B000::1/80
 ipv6 ospf network point-to-point
!         

Task 4
Enable OSPFv3 Area 13 on the above loopbacks. Ensure that the rest of OSPFv3 domain receive a summary route representing all the loopbacks advertised into OSPF in task 3.

R2 Config:
!
interface Loopback1
 ipv6 ospf 1 area 13
!
interface Loopback2
 ipv6 ospf 1 area 13
!         
interface Loopback3
 ipv6 ospf 1 area 13
!         
interface Loopback4
 ipv6 ospf 1 area 13
!         

Verification:
Pic. 2 - R2 and R3 OSPFv3 Neighbors.



Pic. 3 - R4 Receives the Loopback1-4 Network Prefixes.

R3 Config:
!
ipv6 router ospf 1
 router-id 3.3.3.3
 log-adjacency-changes
 area 13 range FC00:1:1:22:8000::/66
!

Verification:
Pic. 4 - R4 IPv6 Connectivity.
