What are the 3 EIGRP topology tables?
What are the 3 EIGRP topology tables?
EIGRP uses three tables: the neighbor table, the topology table, and the IP routing table. The neighbor table keeps state information regarding neighbors, and is displayed using the show ip eigrp neighbors command. EIGRP Update messages fill the routers’ EIGRP topology tables.
How do I display the EIGRP routing table?
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.
What is Srtt and RTO in EIGRP?
SRTT (Smooth round-trip time): The number of milliseconds it takes to send an EIGRP packet to your neighbor and receive an acknowledgment packet back. RTO (Retransmission timeout): The amount of time in milliseconds that EIGRP will wait before retransmitting a packet from the retransmission queue to this neighbor.
What routes are saved in the topology table?
Successor routes are saved in the topology table to be used if the primary route fails. Successor routes are flagged as “active” in the routing table. A successor route may be backed up by a feasible successor route. Successor routes are stored in the neighbor table following the discovery process.
How many tables will EIGRP have?
EIGRP (Enhanced Interior Gateway Routing Protocol) has a specific Neighbour Table for each Layer 3 protocols. For example, if you are using both IPv4 and IPv6 protocols, you will have two different EIGRP Neighbour Tables.
What is EIGRP Neighbour table?
The neighbour table objects establish bindings between protocol addresses and link layer addresses for hosts sharing the same physical link. neighbour object entries are organized into tables. The IPv4 neighbour object table is also known as the ARP table.
Which command is used to examine the ip EIGRP routing table?
#show ip eigrp neighbors
Verifying EIGRP
| Router#show ip eigrp neighbors | Displays the neighbor table. |
|---|---|
| Router#show ip eigrp neighbors detail | Displays a detailed neighbor table. |
| TIP The show ip eigrp neighbors detail command verifies whether a neighbor is configured as a stub router. | |
| Router#show ip eigrp interfaces | Shows information for each interface. |
How do I find the OSPF topology table?
To display Open Shortest Path First (OSPF) details about the topologies configured under the OSPF protocol instance, use the show ip ospf topology-info command in privileged EXEC mode. (Optional) Process ID. If this argument is included, only information for the specified routing process is included.
What is RTO EIGRP?
RTO (Retransmission timeout): The amount of time in milliseconds that EIGRP will wait before retransmitting a packet from the retransmission queue to this neighbor. Q Cnt (Q count): The number of EIGRP packets (Update, Query or Reply) in the queue that are awaiting transmission.
What is EIGRP metric?
EIGRP determines the value of the path using five metrics: bandwidth, load, delay, reliability and MTU. EIGRP uses Five different messages to communicate with its neighbor routers. EIGRP messages are Hello, Update, Query, Reply, and Acknowledgement.
