Cisco Press Example 9-6 also shows the EIGRP hello interval and hold time being set. These parameters can be set per interface using the interface subcommands ip hello-interval eigrp asn seconds and ip hold-time eigrp asn seconds, respectively.

What is the Hello interval in EIGRP?

5 seconds

EIGRP uses a default Hello timer of 5 seconds and a default Hold timer of 15 on LAN interfaces.

What is the command to view EIGRP metric?

If you are unsure of the EIGRP metrics, you can query the parameters for the formula directly from EIGRP’s topology table by using the command show ip eigrp topology network/prefix-length.

How do I check my EIGRP status?

debug ip eigrp Examples. You can use the debug ip eigrp command to verify EIGRP operation. This command displays EIGRP packets that this router sends and receives. Example 3-34 shows the contents of the updates that are reported when you use the debug ip eigrp command on R2 to monitor when an interface on R1 comes up.

What does the show ip EIGRP neighbor command display?

Use the show ip eigrp neighbors command to determine when neighbors become active and inactive. It is also useful for debugging certain types of transport problems.

What are the Hello hold timers in EIGRP for normal and WAN routes?

Hello timer behaviors

  • EIGRP. By default, EIGRP sends hellos every 5 seconds on LAN interfaces and every 60 seconds on WAN interfaces; the hold timer is three times the hello timer (15 or 180 seconds, respectively). …
  • OSPF. …
  • IS-IS. …
  • Summary.

What is network hold time?

The hold time specifies how long a neighbor should consider this routing device to be operative without receiving another hello packet. If the neighbor does not receive a hello packet from this routing device within the hold time, it marks the routing device as being unavailable.

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.

Which command will display EIGRP packets sent and received?

show ip eigrp traffic

The command “show ip eigrp traffic” is used to display the number of EIGRP packets sent and received.

How does EIGRP measure delay?

The delay value used in the EIGRP metric calculation is the delay in 10’s of microseconds. So to calculate the Delay value, simply divide the DLY in the show interface command by 10. The Delay Value of 10 will be plugged into our simplified EIGRP Metric formula we derived earlier.

How do I check EIGRP adjacency?

We now have an EIGRP neighbor adjacency. We can verify this by using the show ip eigrp neighbors command. Lesson learned: Make sure both routers are on the same subnet.

What are the table in EIGRP?

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.

What does show ip route do?

On a Cisco router, the show ip route command is used to display the IPv4 routing table of a router. A router provides additional route information, including how the route was learned, how long the route has been in the table, and which specific interface to use to get to a predefined destination.

What is show command in Cisco?

The show IP route command displays every known connected and destination network, the method used to learn about these networks, the next-hop IP address and the local interface used to get to each known destination network. This command can be used in both User-EXEC and Privileged EXEC mode.

Which command will allow you to view the time details from a configured server?

Explanation : The command show ntp status will allow you to see the current time source, the precision of the time source, and the drift from your internal time clock.

What is show running config command?

The show running-config command shows the router, switch, or firewall’s current configuration. The running-configuration is the config that is in the router’s memory. You change this config when you make changes to the router.

Which command is used to display all known network?


To use the command, just type ipconfig at the Command Prompt. You’ll see a list of all the network connections your computer is using.

Which command displays a login banner hello in a router?

R1#telnet 1.1.

Above you see that the login banner is displayed after the MOTD banner.

Which information does the show interface command display?

The show interfaces command displays statistics for the network interfaces. The resulting display on the Cisco 7200 series routers shows the interface processors in slot order. If you add interface processors after booting the system, they will appear at the end of the list, in the order in which they were inserted.

What is the purpose of the 6 command option?

What is the purpose of the -6 command option? It forces the trace to use IPv6. It limits the trace to only 6 hops. It sets a 6 milliseconds timeout for each replay.

What command displays the contents of the routing table?

netstat -nr command

You can display the routing table’s contents with the netstat -nr command. The -r option tells netstat to display the routing table, and the -n option tells netstat to display the table in numeric form.

What does show CDP neighbors do?

The show cdp neighbors detail command reveals the IP address of a neighboring device. The show cdp neighbors detail command will help determine if one of the CDP neighbors has an IP configuration error. To disable CDP globally, use the global configuration command no cdp run.

What is CDP command?

cdp enable. To enable Cisco Discovery Protocol (CDP) on an interface, use the cdp enable command in interface configuration mode. To disable CDP on an interface, use the no form of this command.

What is hold time in Cisco switch?

The default holdtime is three times the hello interval, which is 15 seconds on most links. Slower links might have a holdtime of 180 seconds and a hello interval of 60 seconds.

How do I view CDP neighbors?

To display information about neighbors, use the show cdp neighbors privileged EXEC command. (Optional) Type of the interface connected to the neighbors about which you want information. (Optional) Number of the interface connected to the neighbors about which you want information.

Which command will show you the IP address of a neighboring device running CDP?

Gathering Neighbor Information

Description Command
Display detailed information about neighboring devices HQ_Router#show cdp neighbors detail
Display detailed information about neighboring devices HQ_Router# show cdp entry *
Display IP addresses of each directly connected neighbor HQ_Router#show cdp entry * protocols

What is show LLDP neighbors?

Description. This command shows LLDP neighbors for a specific AP, or all APs sending or receiving LLDP Protocol Data Units (PDUs). The LLDP protocol allows switches, routers, and WLAN access points to advertise information about themselves such as identity, capabilities, and neighbors to other nodes on the network.
