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
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.
