What is ip bandwidth percent EIGRP?

What is ip bandwidth percent EIGRP?

EIGRP Bandwidth for IPv4 By default, EIGRP uses only up to 50 percent of an interface’s bandwidth for EIGRP information. This prevents the EIGRP process from over-utilizing a link and not allowing enough bandwidth for the routing of normal traffic.

How much bandwidth does EIGRP use?

EIGRP will use up to 50% of the bandwidth so that’s 128 kbps of EIGRP traffic.

How do I check bandwidth in Eigrp?

Bandwidth: The bandwidth value used in the EIGRP metric calculation is determined by dividing 10,000,000 by the bandwidth (in kbps) of the slowest link along the path to the destination network.

What is a disadvantage of using Eigrp automatic summarization?

What is a disadvantage of using EIGRP automatic summarization? It creates inconsistent routing when the network has discontiguous networks.

What are the conditions for Eigrp neighbors?

EIGRP Neighborship Requirements

• The devices must be in the same autonomous system (AS)
• The devices must have the same authentication configuration.
• The devices must have the same k-values.

What is more important when tuning EIGRP delay or bandwidth?

The DELAY command is a powerful command for manipulating EIGRP paths. Since the BANDWIDTH command can end up impacting a lot of other configurations (like QoS), we can use the DELAY command to manipulate EIGRP metrics (and therefore, paths) without having to touch the BANDWIDTH command.

What parameters can be included with EIGRP other that the bandwidth and delay?

The EIGRP path attributes can include hop count, cumulative delay, minimum bandwidth link speed, and RD.

What are the EIGRP hello and hold timer?

The hello timer is the interval at which a router will send “hello” messages to neighboring routers to let them know that the originating router is still online and the hold-down timer is the interval at which to consider a neighbor dead if a hello message is not received during that time window.

What are the hello and dead timers of EIGRP?

EIGRP uses a default Hello timer of 5 seconds and a default Hold timer of 15 on LAN interfaces. However, in some situations on interfaces configured for Frame Relay, the default timers will be greater.

How do I configure bandwidth for EIGRP on an interface?

To configure the percentage of bandwidth that may be used by Enhanced Interior Gateway Routing Protocol (EIGRP) on an interface, use the ip bandwidth-percent eigrp command in interface configuration mode. To restore the default value, use the no form of this command.

How can I prevent EIGRP traffic from saturating my interfaces?

If you have many (low bandwidth) PVCs then it’s possible that EIGRP traffic will completely saturate your interfaces. By default EIGRP will use up to 50% of the interface bandwidth. To prevent EIGRP from flooding your interface (s) we can use the ip bandwidth-percent eigrp command to set this to a lower value.

How do I configure EIGRP to use the received next hop?

Configures the hello interval for the EIGRP routing process designated by an autonomous system number. To instruct EIGRP that the IP next hop is itself, use the ip next-hop-self eigrp command in interface configuration mode. To instruct EIGRP to use the received next hop rather than itself, use the no form of this command.

What is the EIGRP hold time for low speed networks?

The EIGRP hold time is 180 seconds for low-speed, nonbroadcast multiaccess (NBMA) networks and 15 seconds for all other networks. This command was introduced.
