Explanation

LLDP (Link Layer Discovery Protocol) is a vendor-neutral protocol used by network devices to advertise identity, capabilities, and neighbors on a local network, making it ideal for documenting multivendor environments. ICMP is used for network diagnostics (e.g., ping), not device discovery. CDP (Cisco Discovery Protocol) is Cisco proprietary and not suitable for multivendor networks. SIP is a signaling protocol used in VoIP, unrelated to infrastructure documentation. LLDP is the correct choice for discovering and documenting multivendor network infrastructure.
