Automation and Programmability

A network engineer needs to create a diagram of a multivendor network.

Which command must be configured on the Cisco devices so that the network topology can be mapped?

  • A Device(config)#lldp run
  • B Device(config)#cdp run
  • C Device(config-if)#cdp enable
  • D Device(config)#flow-sampler-map topology
Explanation

LLDP is the standards-based Layer 2 discovery protocol used to advertise and learn neighbor identity, capabilities, and interconnections in multivendor networks. On Cisco devices, LLDP is enabled globally with lldp run, which allows topology-mapping tools and neighboring devices to discover Cisco nodes in a mixed-vendor environment. CDP is Cisco-proprietary, so it does not satisfy the multivendor requirement.
