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.
An engineer is implementing a route map to support redistribution within BGP. The route map must be configured to permit all unmatched routes. Which action must the engineer perform to complete this task?
Refer to the exhibit. During the last maintenance window, the network engineering team performed multiple software upgrades and enabled OSPFv3 for future use. However, when the network came up, the connection between HQ and the remote branch failed. A network engineer determined that routers R1 and R2 failed to establish an OSPFv2 adjacency. R1 was preconfigured with the point-to-point OSPF network type, and R2 as broadcast. The engineer confirmed that all connected interfaces are up, and the routers can reach one another via ICMP.
Which action must the engineer take to resolve the issue?
Refer to the exhibit. A network engineer with an employee ID 4402:98:032 is setting up an IS-IS network with these requirements:
- Routes with a tag of 80 and IP prefixes other than 192.168.10.20/24
must be redistributed from Level 1 into Level 2
- Route leaking must be configured from Level 2 into the Level 1 domain for routes that are tagged with only 50 or 40 Which configuration must be implemented on RB to meet the requirements?
