When configuring a Frame Relay connection what is the purpose of Inverse ARP?
to create a mapping of DLCI to Layer 3 addresses that belong to remote peers
What protocol map ip addresses to layer 2 addresses?
ARP - Address Resolution ProtocolARP - Address Resolution ProtocolARP - Address Resolution ProtocolARP - Address Resolution Protocol
Why would you want to map an ip address to a dlci?
When the router wants to send traffic to an IP address across a Frame Relay link, it needs to tell the frame switch which PVC the traffic should traverse. A frame switch drops any traffic it receives that has no DLCI in the header, because it has no way of determining how to route the data.
What protocols are used to inquire if an address is reachable on the Internet?
Domain Name System (DNS) and Address Resolution Protocol (ARP) are used for address resolution. Internet Control Message Protocol (ICMP) is also used to determine if an address is reachable.DNS maps a hostname to an IP address and ARP is used to map an address to a physical network hardware address.ICMP messages are typically generated in response to network errors for diagnostics and route tracing but are used to ping an address.
Which protocol can be used by Router1 to determine the IP address of Router2 when they are directly connected and only layer 2 connectivity exist between them?
Answer = ARPMeaning of ARP - "Address Resolution Protocol", is used to map IP Network addresses to the hardware (Media Access Control sub layer) addresses used by the data link protocol. The ARP protocol operates between the network layer and the data link layer in the Open System Interconnection (OSI) model.
What is ARP request?
The address resolution protocol (arp) is a protocol used by theInternet Protocol (IP) , specifically IPv4, to map IP network addresses to the hardware addresses used by a data link protocol. The protocol operates below the network layer as a part of the interface between the OSI network and OSI link layer. It is used when IPv4 is used over Ethernet.There are four types of arp messages that may be sent by the arp protocol. These are identified by four values in the "operation" field of an arp message. The types of message are:ARP requestARP replyRARP requestRARP replyARP request:If a host with the IPv4 address 10.10.10.123 and MAC address 00:09:58:D8:11:22 needs to send a packet to another host with the IP address 10.10.10.140, but does not have its MAC address, then the host sends an ARP request to resolve the unknown address.
Which protocol is used to create a map of local area network devices?
STP
What is the function of ARP?
The function of ARP (address resolution protocol) is to obtain the MAC address of a host, and then map that MAC address to the host's IP address. This protocol is used to translate physical addresses to internet protocol (IP) addresses. A physical address can be the MAC (Media Access Control) address of a network card inside of a computer. The information about which hardware address is associated with which IP address is usually stored in a table on each computer, the so-called ARP table. In essence, ARP is used so that machines on the same network can find each other. It facilitates data exchange between computers on the same network.
What is a private MAC address?
A MAC address is unique to your ethernet card. MAC addresses are used within an Ethernet network to uniquely identify the source and destination of Ethernet frames. ARP (Address Resolution Protocol) is used on IP networks to map IP addresses to MAC addresses within an Ethernet network.
What is page map table?
Used for address translation
What routing protocol depends on the dual algorithm to calculate the shortest path?
Enhanced Interior Gateway Protocol It is a Cisco proprietary protocol. It uses bandwidth and delay by default to calculate the best path. It can also use load and delay, but these are usually not used. It is a distance vector routing protocol. It keeps a topology map, but it is only similar to the topology map of link state routing protocols.
How does the Address resolution protocol stack map the logical IP address to the physical MAC address on a LAN?
The Mapping is done in the ARP table. C:\Documents and Settings\martin>arp -a Interface: 10.1.1.3 --- 0x6 Internet Address Physical Address Type 10.1.1.1 00-22-b0-8e-94-41 dynamic
