A. B. C. D.C
The configuration in the exhibit shows that the IS-IS protocol is enabled on two interfaces - lo0.0 and ge-0/0/0.100. However, it does not explicitly mention which IS-IS levels are enabled on each interface.
In IS-IS, there are three levels of routing domains: Level 1, Level 2, and Level 1-2. Level 1 is used for intra-area routing, Level 2 is used for inter-area routing, and Level 1-2 is used for routing between Level 1 and Level 2 domains. Each router in an IS-IS network must be assigned to at least one level.
To determine which IS-IS levels are enabled on the ge-0/0/0.100 interface, we need to look at the router's overall IS-IS configuration. In the exhibit, the IS-IS configuration is shown as follows:
kotlinprotocols { isis { interface lo0.0; interface ge-0/0/0.100; } } This configuration specifies that the router has two IS-IS interfaces - lo0.0 and ge-0/0/0.100. Since the configuration does not include any explicit IS-IS level statements, the router will enable all IS-IS levels on both interfaces by default.
Therefore, the correct answer is option D - Level 1, Level 2, and Level 3 are all enabled on the ge-0/0/0.100 interface.
