Question #: 14
Topic #: 3
Refer to the exhibit.

Examine the physical topology of the IS-IS network, the metrics of the links and the levels of the routers. All routers have their system interfaces included in IS-IS. Which of the following statements describes the route-table entry that router R4 will use to reach the system IP address of router R6?

Suggested Answer: A Vote an answer

Router R4 is in Area 49.0001 and R6 is in Area 49.0002. Both routers are Level 2 (L2), meaning that they can communicate across areas using Level 2 IS-IS routing.
Since R2 is the L1/L2 router that connects both Area 49.0001 and Area 49.0002, it will be the next-hop for router R4 to reach R6's system IP address.
The IS-IS protocol will ensure that R4 will have a route to R6's system IP address via R2 as the next-hop.
