What is EIGRP routing table?
EIGRP Routing Table is the table which keeps the Best Routes to any destinations. This Best Routes are Successors. You can see the EIGRP Routing Table with “show ip route eigrp” command.
How does EIGRP build its topology table?
Each router builds a neighbor table from the hello packets it receives from adjacent EIGRP routers running the same network layer protocol. EIGRP maintains a neighbor table for each configured network-layer protocol.
Where you can find the topology table?
A topology table is used by routers that route traffic in a network. It consists of all routing tables inside the Autonomous System where the router is positioned.
Which command can be used to display the topology table of EIGRP?
Verifying EIGRP
| Router#show ip eigrp neighbors | Displays the neighbor table. |
|---|---|
| Router#show ip eigrp topology | Displays the topology table. |
| TIP The show ip eigrp topology command shows you where your feasible successors are. | |
| Router#show ip eigrp traffic | Shows the number and type of packets sent and received. |
What is difference between EIGRP and OSPF?
Key Differences Between EIGRP and OSPF. EIGRP is an advanced distance vector routing protocol which uses incremental and triggered updates. On the other hand, OSPF is a link-state routing protocol which resembles a map where the complete information about all the routes within that area is maintained.
What attributes does the EIGRP topology table contain?
The EIGRP path attributes can include hop count, cumulative delay, minimum bandwidth link speed, and RD. The attributes are updated each hop along the way, allowing each router to independently identify the shortest path. Figure 2-9 shows the information in the EIGRP update packets for the 10.1.
What is EIGRP and how does it work?
EIGRP is a distance vector & Link State routing protocol that uses the diffusing update algorithm (DUAL) (based on work from SRI International) to improve the efficiency of the protocol and to help prevent calculation errors when attempting to determine the best path to a remote network.
What are three features of EIGRP?
The characteristics of EIGRP follow:
- Hybrid routing protocol (distance vector that has link-state protocol characteristics).
- Uses IP protocol 88.
- Classless protocol (supports VLSMs).
- Default composite metric uses bandwidth and delay.
- You can factor load and reliability into the metric.
What is true EIGRP?
Explanation: EIGRP stands for Enhanced Interior Gateway Routing Protocol is a routing protocol designed by Cisco. It is available only on Cisco routers. Explanation: EIGRP metric is K-values which are integers from 0 to 128. They are used to calculate the overall EIGRP cost with bandwidth and delay metrics.
What is the purpose of the EIGRP neighbor and topology tables?
neighbor table The neighbor table holds a list of all the routers EIGRP has established a neighborship with. topology table The topology table keeps track of the entire network topology. It stores all the information about all the routes that the router has received from its neighbors, even duplicate routes.
How do I find my EIGRP number?
To display the number of various EIGRP packets sent and received, use the show ip eigrp traffic command, as illustrated in Example 3-31. For example, in this network, router R1 has sent 429 hello messages and received 192 hello messages.
