How do I distribute a default route in EIGRP?

How do I distribute a default route in EIGRP?

One way to inject a default route into EIGRP is to configure a static default route pointing to Null0 and then redistribute the default route into EIGRP. When redistributing a static, connected, or EIGRP route for another AS, the metric does not need to be assigned. The default route will be an external EIGRP route.

How are the routes distributed with the EIGRP protocol?

EIGRP is a dynamic routing protocol by which routers automatically share route information. This eases the workload on a network administrator who does not have to configure changes to the routing table manually.

Can you run OSPF and EIGRP on the same router?

you can run them both but the AD of EIGRP is 90 , OSPF 110 Eigrp routes will be preferred .

What is the default metric used when redistributing OSPF into EIGRP?

The default metric-type for redistributed routes in OSPF is E2 which means that the metric remains the same throughout the OSPF network. If you had another router behind R3 running OSPF, you would still see the redistributed routes with a metric of 20.

What is the default metric for EIGRP?

The EIGRP formula is based on the IGRP metric formula, except the output is multiplied by 256 to change the metric from 24 bits to 32 bits. Taking these definitions into consideration, the formula for EIGRP is shown in Figure 2-7. By default, K1 and K3 have a value of 1, and K2, K4, and K5 are set to 0.

What is default route in EIGRP?

Static Default Route We configure the default route on R2 with FastEthernet 0/1 as the exit interface. In EIGRP we can use the network 0.0. 0.0 command to advertise this.

What is default route in OSPF?

In OSPF, the “default-information originate” command will not advertise to any other routers without a default route in the routing table. When added the “always” keyword , it tells the router to advertise a default route to other routers even if you don’t have a default route in the routing table.

What is OSPF and EIGRP?

EIGRP (Enhanced Interior Gateway Routing Protocol) and OSPF (Open Shortest Path First) are two common Interior Gateway Protocols (IGP) specifying how routers or data switches communicate with each other. They are often applied in different situations for varied performance on speed, delay, etc.

Which type of routing protocol is OSPF?

link-state routing protocol
Open Shortest Path First (OSPF) is a link-state routing protocol that was developed for IP networks and is based on the Shortest Path First (SPF) algorithm. OSPF is an Interior Gateway Protocol (IGP).

Which routing protocol is best between OSPF and EIGRP?

Both of them could be widely deployed in Internet Protocol (IP) networks for data communication. EIGRP is a popular choice for routing within small and big campus networks. While OSPF is the best choice when your network hardware devices come from various vendors.

Why OSPF is preferred over EIGRP?

In EIGRP you can summarize networks on any EIGRP router in the network however with OSPF you can only perform summarization on the ABR and ASBR routers. EIGRP supports un-equal load balancing where as OSPF does not.

How to advertise default route in EIGRP?

These methods are available in order to advertise default route in EIGRP which are explained in this article: 1. Use default route and redistribution 2. Use Summary address Here routers R1, R2 and R3 are configured with EIGRP and no EIGRP runs in between R3 and R4.

How do I redistribute OSPF to EIGRP?

Redistribute OSPF into EIGRP. First, we’ll redistribute OSPF into EIGRP. We do this under the EIGRP process: R2(config)#router eigrp 12. Let’s take a look at the redistribute ospf options: R2(config-router)#redistribute ospf? <1-65535> Process ID. We need to select the correct OSPF process. In our example, that’s process ID 1.

How do I redistribute a default route into OSPF?

You cannot redistribute a default route into OSPF. You can only have it injected using the default-information originate command.

Does EIGRP run between R3 and R4?

Here routers R1, R2 and R3 are configured with EIGRP and no EIGRP runs in between R3 and R4. ! ! ! ! Method 1. Use Default Route and Redistribution
