Topology
Notice!
IPv6 addresses have changed. Follow the below topology diagram and tasks to accomplish the goals.
Pic1. IPv6 Topology Diagram.
Task 1
Configure manual IPv6 addresses on Frame-Relay connections between R3, R4, and R6. IPv6 global addresses should reflect the topology diagram. Host portion of the address should be ::X. For link-local addresses use: FE80::X. In both cases 'X' is the router's number (3, 4, and 6).
Task 2
Enable OSPFv6 area 0 between the routers mentioned in Task 1 using the default OSPF mode. OSPF router's IDs should be as follows:
- R3 - 3.3.3.3
- R4 - 4.4.4.4
- R6 - 6.6.6.6
Task 3
Advertise into OSPF the following Loopback addresses:
- R3 - FC00:A:A:A::3/128
- R4 - FC00:A:A:A::4/128
- R6 - FC00:A:A:A::3/128
