we have learned to set up links with high redundancy dynamic routing protocol OSPF also have conducted verification tests which occur in the reality of any company.
The network administrator will be in charge of giving priority to the link that provides the best performance
at end of the course:
You will be able to configure OSPF with Link Redundancy
configure Redundancy Link high availability
You will be able to test routes principal and backup
the student will be able to configure and verify that the configured network does not have any logical failure and network traffic is not interrupted

|Section 1: Introduccion|
The theme that we will see is redundant links with the dynamic routing protocol OSPF, in all practices dictate that it is best to be practical examples which have been applied to the reality of a company
I have here the scheme will implement in our simulator tracer packet least 3 routers with their three respective lans , the first objective is to interconnect LANs and routers so that all have connectivity to each other. Routers be interconnected to each other by 2 links the first fiber optic giving priority 1 and the second would be a wireless link giving priority 2 The second goal when the fiber optic link is turned off , the other wireless link to work immediately
|Section 2: Configurando Ospf|
first step we will add three generic routers.
R1: A fiber interface and two fastethernet.
R2: two fiber interfaces and 3 fastethernet.
R3: A fiber interface and two fastethernet.
then we will add 3 switch of any model and leave them with settings in Layer Two.
and 3 end devices which can be "PCs"
see in the scheme.
The following addressing scheme will be used.
R1 - R2: Fiber Link: 10.10.10.0/30, Wireless Link: 10.20.20.0/30
R2 - R3: Fiber Link: 10.10.10.4/30, Wireless Link: 10.20.20.4/30
R1: Lan Gateway: 192.168.1.254/24
R2: Lan Gateway: 192.168.2.254/24
R3: Lan Gateway: 192.168.3.254/24
we will configure the routing protocol OSPF interfaces on routers that have connectivity to each other and in their LANS
|Section 3: Set Priority Link|
we will give priority to the link from R1 to R2 so that all traffic is directed through the fiber optic link.
we will give priority to the link from R2 to R3 so that all traffic is directed through the fiber optic link.
|Section 4: Testing High Availability|
the most important part check the links and verify that the wireless link work when no fiber optic link is active
8 years of experience in networking and telecommunications companies both private enterprise and government and support technique
when I started assembling computers, acquire a lot of experience but my thing is networking and communications
Expert in Cisco, Mikrotik, Checkpoint, VMware, Elastix VOIP, Hp switching.
Courses and certifications such as:
Networks and Transmission
I like that all courses or laboratories can be applied to the reality of a company or business
in my career I have had deployments and mikrotik cisco because they are very robust equipment and implementations I've done is that during the I shared with you
I loved tecnology cisco, mikrotik and checkpoint
my hobby is the computer also in my other life I should have been a runner I love cars and I also do some maintenance on my car vehicle
