Implementing Cisco Data Center Infrastructure (DCII, legacy) — Question 1

Which command should you run to limit IS-IS LSP flooding on a network?

Answer options

• A. isis hello-padding
• B. isis passive-interface
• C. is-type level-1
• D. isis mesh-group ISIS-MESH

Correct answer: C

Explanation

The correct command, 'is-type level-1', is used to limit the scope of LSP flooding to Level 1 routers only in an IS-IS network. The other options, such as 'isis hello-padding' and 'isis passive-interface', do not control LSP flooding, while 'isis mesh-group ISIS-MESH' is related to optimizing link utilization rather than limiting flooding.
