A network engineer is troubleshooting OSPF multiare

Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?

Which Cisco IOS XR feature should the engineer use in order to streamline OSPF issue?

hierarchical CLI

hierarchical CLI

DR support for topology management

DR support for topology management

routing process enabled by default on all interfaces

routing process enabled by default on all interfaces

show ip ospf topology command

show ip ospf topology command

Suggested 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.

Suggested answer: A
Explanation:

A shared tree is built first between receiver and the RP. The receiver is then able to switch to a Source tree as needed.

BFD is not compatible between Cisco IOS XR and Cisco IOS Software.

BFD is not compatible between Cisco IOS XR and Cisco IOS Software.

Suggested answer: C
Explanation:
