What is feasible distance?
Feasible distance (FD) – the local router’s metric of the best route to reach a specific network. The metric is calculated using the metric reported by the neighbor (the advertised distance) plus the metric to the neighbor reporting the route. The route with the lowest FD will be placed in the routing table.
What is the use of Eigrp?
Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration. The protocol was designed by Cisco Systems as a proprietary protocol, available only on Cisco routers.
Why Eigrp is better than Rip?
The main advantage of using RIP is it uses the UDP (User Datagram Protocol). 2. Enhanced Interior Gateway Protocol (EIGRP) : EIGRP stands for which allows router to share information to the neighboring routers which are within the same area
Is OSPF better than Eigrp?
OSPF scales better than EIGRP because EIGRP is more complex in very large scale networks while troubleshooting. Compared to EIGRP, OSPF is better to use on WAN since most of the service providers support it. OSPF have already been running in internal environments as an IGP (Interior Gateway Protocol)
What do you feel is the greatest benefit of using Eigrp?
EIGRP is a simple protocol to understand and deploy. It’s IPv6-ready, scales effectively in a well-designed network, and provides extremely quick convergence times. Other EIGRP advantages include: Easy transition to IPv6 with multi-address family support for both IPv4 and IPv6 networks.
Is Eigrp Classful or classless?
Classful routing protocols do not carry subnet masks; classless routing protocols do. Older routing protocols, including RIP and IGRP, are classful. Newer protocols, including RIP-2, EIGRP, and OSPF, are classless.
Is BGP Cisco proprietary?
This is a value that is local to the router and it’s Cisco proprietary. The default value is 0 for all routes that are not originated by the local router. You can learn how it works in the BGP weight attribute lesson.
What is Eigrp metric?
EIGRP updates contain five metrics: minimum bandwidth, delay, load, reliability, and maximum transmission unit (MTU). Of these five metrics, by default, only minimum bandwidth and delay are used to compute best path
What is offset list?
An offset list is the mechanism for increasing incoming and outgoing metrics to routes learned via EIGRP or Routing Information Protocol (RIP). (Offset lists are only used for distance vector routing protocols.) Optionally, an offset list can be limited by specifying either an access list or an interface
How Eigrp metric is calculated?
Bandwidth: The bandwidth value used in the EIGRP metric calculation is determined by dividing by the bandwidth (in kbps) of the slowest link along the path to the destination network. Delay: Unlike bandwidth, which represents the “weakest link,” the delay value is cumulative
What are the K values in Eigrp?
K values are integers from 0 to 128; these integers, in conjunction with variables like bandwidth and delay, are used to calculate the overall EIGRP composite cost metric
What is as number in Eigrp?
For EIGRP and BGP, the number is an autonomous system (AS) number. But for OSPF, the number is a process number. Of course, in your network, all the routers need the same AS number, which can generally be anything from 1 to 65535. BGP, which is an exterior gateway protocol, uses this number extensively.
What is the administrative distance for Eigrp?
By default, OSPF has a default administrative distance of 110 and RIP has a default administrative distance of 120….Cisco.
| Routing Protocol | Administrative distance |
|---|---|
| External BGP | 20 |
| Internal EIGRP | 90 |
| IGRP | 100 |
| OSPF | 110 |
What is the default hop count of Eigrp?
EIGRP supports a variety of network protocols. It can provide routing support for IPv4, IPv6, Internetwork Packet Exchange (IPX), and AppleTalk. Similar to its predecessor IGRP, EIGRP has a maximum hop count of 224 and a default maximum hop count of 100. EIGRP has administrative distance of 90.
Where should we use default routing?
Explanation: We must use default routing on stub networks. They have only one exit path out of the network, so there can be no specific path decided for such networks.
What is the maximum hop count?
hops-number. Maximum hop count. The range is from 1 to 255 hops.
What happens when a router receives a packet with a TTL of 0?
What happens when a router receives a packet with a TTL of 0? The router drops the packet and sends an ICMP TTL expired message back to the host. The hosts will still send and receive traffic, but traffic may not always reach the correct destination.
What happens when a router receives a packet?
When a router receives a packet, the router checks its routing table to determine if the destination address is for a system on one of it’s attached networks or if the message must be forwarded through another router. It then sends the message to the next system in the path to the destination.
What occurs when a collision happens on a network?
What occurs when a collision happens on a network? a. The collision will create an error in the network switch, but otherwise, no issues will occur as a result. Each node on the network waits a random amount of time and then resends the transmission.
What command will list only current connections?
netstat -n
What is by far the most popular DNS server software available?
BIND
Does IPv4 and IPv6 use the same packet format?
IPv4 and IPv6 use the same packet format. As a network support technician, you only need to know how to support IPv6. On IPv4 networks, IGMP operates at the Network layer of the OSI model to manage multicasting.
Is the protocol that reports the success or failure of data delivery?
ICMP (internet control message protocol) reports on the success or failure of data delivery.
What problem does the DNS solve?
What does the DNS solve? the problem of name resolutions. Does this through servers configured to act as name servers. The servers run DNS server software, which enables them to receive, process, and reply to requests from systems that want to resolve hostnames to IP addressess.
What is the fundamental protocol that the Internet uses today?
The primary networking protocol used on the Internet today is referred to as TCP/IP.
Why is TCP IP important?
TCP/IP Model helps you to determine how a specific computer should be connected to the internet and how data should be transmitted between them. It helps you to create a virtual network when multiple computer networks are connected together. The purpose of TCP/IP model is to allow communication over large distances
