It's pretty amazing to see a dynamic routing protocol
at work.
So here's what we're going to do this Nugget.
We're going to demonstrate three different dynamic routing
protocols on our topology right here.
And, currently, the only networks
that the routers know about are the ones
that they're directly connected to.
So there's R1, which is directly connected networks.
Here's R2, and then here's R2.
Fantastic.
Let's go ahead and add RIP.
What this does-- it goes into configuration mode on each
router, tells the router we want to run the RIP routing
process--
and specifically version 2--
that we do not want to do any type
of automatic summarization, and we want any interfaces that
begin with the IP address of 10 anything
to be included as part of this RIP routing process.
So we'll send that script to all three routers.
So here in R1, it's learned four routes.
It learned about the 10.4, 10.5, 10.7, and 10.8 networks.
Here on router 2, it's learned about the 10.1, 2, 6,
and 8 networks.
And on router 3, it's learned about the 10.1, 2, 3, 4,
and 5 networks.
Fantastic.
Next, we're going to send the command
to remove the RIP router process and then put in the EIGRP.
We're also telling EIGRP to include the interfaces that
begin with 10.
So we'll send that out to all three routers, as well.
And you'll notice we have some neighbor adjacencies that
have come up.
Fantastic.
And let's take a look at the routing table
on all three routers, as well.
And R1, via EIGRP, has now learned dynamically
these networks.
R2 has learned these networks, and R3
has learned these networks.
So, next, we're going to remove EIGRP routing process,
and in its place, we're going to put in OSPF process ID 1.
And this network statement effectively, in Cisco world,
says, we want to include every interface
that the router's running as part of this OSPF routing
process.
So with that in place, we'll send that to all three routers,
as well.
Next, we have some messages regarding the OSPF neighbor
[INAUDIBLE] being set up.
All three routers know how to reach the other networks
in our topology, this time because they learned it
dynamically via the OSPF routing protocol.
So here's router 1.
Here's router 2.
And here's router 3.
In this Nugget, we've demonstrated
three dynamic routing protocols, RIP version 2, EIGRP, and OSPF.
I hope this has been informative for you,
and I'd like to thank you for viewing.
