A network administrator is using an application that is monitoring packets on the network and sees an EIGRP update packet What is the purpose of the update packet?
bobo The packet is sent to discover neighbors within the EIGRP network. The packet is sent to search for network devices within an EIGRP network. The packet is used to propagate routing information within the EIGRP network. The packet is used to send an unreachable reply to another router within the EIGRP network.
What is the purpose of time to live field within a packet header?
There may sometimes be a problem, usually temporary, that data is sent back and forth, or goes around in a loop, due to some routing error. If this happens, the data will eventually be discarded. Every time a packet is re-sent, the TTL is reduced by one; when it goes down to zero, the packet "dies".
What is the TTL - Time to Live and Why is it required?
TTL is a value in data packet of Internet Protocol. It communicates to the network router whether or not the packet should be in the network for too long or discarded. Usually, data packets might not be transmitted to their intended destination within a stipulated period of time. The TTL value is set by a system default value which is an 8-bit binary digit field in the header of the packet. The purpose of TTL is, it would specify certain time limit in seconds, for transmitting the packet header. When the time is exhausted, the packet would be discarded. Each router receives the subtracts count, when the packet is discarded, and when it becomes zero, the router detects the discarded packets and sends a message, Internet Control Message Protocol message back to the originating host.
What is the purpose of the update packet?
The packet is sent to discover neighbors within the EIGRP network.
What is the background information for truecrypt?
TrueCrypt is a freeware software application used for on-the-fly encryption (OTFE). It can create a virtual encrypted disk within a file or encrypt a partition or the entire storage device.
How is the header file include within a program?
#include or#include "nameoftheader"
Is a UDP packet smaller than a TCP packet?
In general, yes, using UDP transport will use a smaller packet than TCP. UDP generally assumes that the complete message will fit within a single packet, unlike TCP which will segment or break apart a message into multiple packets for guaranteed reliable delivery. UDP has no such requirement to deliver anything within a reliable framework and would like to keep the entire message within a single packet and eliminate the segmentation and reassembly process.
What is difference between routing and switching?
Switching involves moving packets between devices on the same network. *Conversely, routing involves moving packets between different networks.Switching is able to determine where a packet should be sent by examining the MAC address within the data link header of the packet (the MAC address is the hardware address of a network adapter).A switch maintains a database of MAC addresses and what port they are connected to.(operate at layer 2 of the OSI model).Routers, on the other hand, operate at layer 3 of the OSI Model.A router is able to determine where to send a packet using the Network ID within the Network layer header. It then uses the routing table to determine the route to the destination host.
What is the purpose of the TTL field within an IP packet header?
clears an unreachable route from the routing table after the invalid timer expires prevents regular update messages from inappropriately reinstating a route that may have gone bad removes an unreachable route from the routing table after the flush timer expires limits the period of time or number of hops a packet can traverse through the network before it should be discarded used to mark the route as unreachable in a routing update that is sent to other routers
What do the letters mpls stand for?
The letters mpls are short for Multiprotocol Label Switching, an IETF initiative that integrates Layer 2 information about network links within an ISP. The purpose of this is to simplify and improve IP-packet exchange.
What is the purpose of the Cisco IOS enable secret command?
This command provides the ability to the administrator to enter an encrypted form of the enable password. If the administrator uses the enable password command the password is stored in plain text within the startup config file. If enable secret is used, the password is stored as an encrypted string within the startup config file.
Is more efficient than TCP for carrying messages that fit within one data packet?
UDP
