Describe 4 different scenarios when an ip router would drop packets that arrive on one of its interfaces?
1) ACL (Access Control List) policy instructs the router to drop it. This is a "rule" configured intentionally by the router's administrator to control traffic.
2) The packed fails an RPF (Reverse Path Forwarding) check. This is when a packet arrives with a source address that doesn't make sense, and it appears like an attempt at malicious activity.
3) The input queue is full. This is basically a symptom of the router being overloaded.
4) The packet fails a basic sanity check, such as TTL (Time to Live) expiring, or failing a CRC (Cyclic Redundancy Check), although that is actually a Layer 2 function, not IP.
5) The packet has a requirement that the router is unable to accomodate. Examples of this would be a non-UDP encapsulated IPSec packet whos destination address requires translation, or a multicast packet arriving at a router that is not configured for multicast routing.
What else can I help you with?
Which two parameters are stored in the routing table?
the best route to reach remote networks the interfaces used to forward packets
What are true of CDP packets?
They are mostly made up of ASCII strings THey may include information about CDP interfaces and neighbor entries
Which statements describe characteristics of extended access lists?
They check packets by source address They check packets by destination address
how are packets assigned to the VLAN?
VLAN: How are packets distributed with respect to the different classifications?
What statement is true regarding how packets will travel from the 172.16.1.0 16 network to the 192.168.200.0 24 network?
The router installs all the equal cost paths in the routing table and performs equal cost load balancing to send packets out multiple exit interfaces.
What is the router interface?
A router interface is a point of connection between the router and a network segment, allowing data to flow in and out of the router. Each interface can be assigned an IP address, enabling routing decisions based on the destination of the data packets. Interfaces can be physical (like Ethernet ports) or virtual (like VLAN interfaces), and they play a crucial role in the router's ability to manage traffic and connect different networks.
What topology passes special network packets?
For WANs depending on the protocol the packets can be very different. For LANs, the ring topology insists on special packets proceeded by a "token".
Name 2 networking devices that transmit packets based on MAC address?
A MAC address is used as a unique identifier that is assigned to network interfaces. Two networking devices that transmit packets based on MAC addresses are switches and bridges.
What two statements describe packets that are sebt through a linksys integrated router using NAT?
Packets sent through Linksys integrated router using NAT can be described in two ways. First, packets have to be translated if they are sent to another LAN, and secondly, packets sent to hosts within the same LAN need no translation.
What are the difference between packets and sockets?
Sockets are were you would put in electrical outlets. Packets are a little more advances and can hold numerous different charges.
Why are the EOG packets different colors?
I believe it is for security measures (cheating)
What hardware is required for packet switching?
Packet switching requires networking hardware such as routers and switches. Routers direct data packets between different networks, while switches manage data packets within a local network, forwarding them to the correct devices based on their MAC addresses. Additionally, network interfaces and cabling are necessary to connect devices and facilitate communication. Overall, this combination enables efficient data transmission and handling in packet-switched networks.
