A. B. C. D. E.AB
LLDP (Link Layer Discovery Protocol) is a vendor-neutral Layer 2 protocol used to exchange device information on a local network. LLDP can exchange various pieces of information called TLVs (Type-Length-Value), including the following:
A. Device Management Address: This TLV is used to share the device's management address, such as its IP address or MAC address. The management address is the address used to access the device for configuration, monitoring, or troubleshooting purposes. This TLV is helpful in discovering neighboring devices and their management addresses, allowing network administrators to manage network devices more efficiently.
B. Device Type: This TLV is used to share information about the type of device, such as a switch, router, access point, or host. The device type information can help identify the roles of neighboring devices and understand their capabilities. For example, knowing the device type can help identify the network segment to which a particular device is connected.
C. Spanning-Tree Topology: LLDP can also share information about the spanning-tree topology of a network. This TLV can help identify the root bridge, bridge priorities, and the path cost between devices in the network. This information is useful in troubleshooting network problems and optimizing the network topology.
D. Routing Configuration: LLDP can share routing configuration information, including the routing protocol used, the neighbor router's IP address, and the autonomous system number (ASN). This information can help identify the routing infrastructure and detect any potential routing problems.
E. Access-list Configuration: LLDP can also share information about the device's access-list configuration, including the access-list number, source and destination IP addresses, and port numbers. This TLV can help identify which access-lists are being used in the network and the filtering policies that are in place.
However, in the given options, only options A and B are the two pieces of information that can be shared with LLDP TLVs. Options C, D, and E are not shared with LLDP TLVs.
