Topology

Tasks
Green future Service Provider has decided to implement ISIS in core network with dual-stack capability. As per Network design, it is Multi-Area ISIS configuration for IPv4 and IPv6. Routers in Western Area are in Area 49.0275 and Routers in Northern Area are in Area 49.0265. According to design guidelines, implement independent SPF calculation for IPv4 and IPv6. For future scalability, NW should also have wider metric fields to support MPLS Traffic Engineering when required. Below tasks to be achieved to complete the implementation.
1) Task 1
Configure appropriate interface of Western_R1 to establish ISIS adjacency with Northern_R2 for IPv4 and IPv6. Similarly, configure appropriate interface of Western_R4 to establish ISIS adjacency with Western_R4 for IPv4 and IPv6.
Note. Adjacency to be established with default level type.
2) Task 2
Enable ISIS multi-topology on Northen_R5 and Northern_R6 for address-family IPv6. Both routers should generate and accept new-style TLVs. This is to prepare the NW for future NW expansions such as MPLS traffic engineering.
