- A. Router 1 and Router 2 are participating in SR-TE tunnels and are both head-end routers.
- B. Router 1 centrally learns the topology of the network to aid in SR-TE path selection, and Router 2 is a node that feeds Router 1 topology information.

NEW QUESTION # 104
A network engineer is troubleshooting OSPF multiarea.
Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?
- A. hierarchical CLI
- B. show lp ospf topology command
- C. routing process enabled by default on all interfaces
- D. DR support for topology management
Answer: A
Explanation:
OSPF Hierarchical CLI and CLI Inheritance
Hierarchical CLI is the grouping of related network component information at defined hierarchical levels such as at the router, area, and interface levels. Hierarchical CLI allows for easier configuration, maintenance, and troubleshooting of OSPF configurations. When configuration commands are displayed together in their hierarchical context, visual inspections are simplified.
Hierarchical CLI is intrinsic for CLI inheritance to be supported.
With CLI inheritance support, you need not explicitly configure a parameter for an area or interface. In the software, the parameters of interfaces in the same area can be exclusively configured with a single command, or parameter values can be inherited from a higher hierarchical level - such as from the area configuration level or the router ospf configuration levels.
