GNS3 Nexus (NX-OSv) switch setup and configuration Part 2: GNS3 switching options Part 13

in this video I'm going to show you how to import and configure a Nexus switch in gns [Music] 3 so what I'll do now is start up the devices and open up a [Music] console as you can see here the Nexus switch is booting up and so are the two iOS V roders now this is going to take a while so I'll pause the video essentially you just need to wait for the Nexus switch to boot up you can see that the image is being decompressed if you see an error such as the following just wait and after a while you get a login prompt default username is admin default password is admin notice we now logged in to a Nexus osv switch so show run as an example shows us the configuration of the switch you can see as an example that the ports are shut down notice the interface numbers interface ethernet 21 and ethernet 22 which is different to the default names that gns3 allocated but we'll fix that in a moment there's some other output but what we'll do now is change the host name of the switch to Nexus as an example show CDP neighbor at the moment we don't see any neighbors so let's configure r one and R 2 so here's r one host name R1 interface gigabit 00 no shut I'll give this an IP address of 10111 255 255 255 Z show CDP neighbor we may have to give it some time so let's go on to WR a two host name is R2 interface gigabit 0/0 no shut IP address [Music] 10.12.2 the Nexus is by default using the no switch Port command so the interfaces are routed interfaces notice no switch Port the interfaces are also shut down so no wonder we're not seeing neighbor relationships so I'll say interface ethernet 2/1 to 10 no shut so show CDP neighbor here we are seeing the next switch as a neighbor but notice the port is 2/3 and on this side show CDP neighbor we seeing a Nexus switch but the interface is ethernet 2/2 so these interface numbers need to be changed to 2/2 and 2/3 once again on rou 1 show CDP neighbors shows us that and the same is true on rter 2 so what we can do now is change the interface configuration notice the difference to iOS you can do Show run as an example in config mode we don't need to type do Show run the two interfaces that we are concerned with are 2/2 and 23 so interface ethernet 22 IP address 10125 4/24 you can't do that in iOS as an example 23 IP address 1012 25424 so ping 10111 notice we can ping r a one we can ping hopefully r a two yes we can so just to prove the point debug IP icmp the Nexus switch caning r one debug IP icmp wrong switch or wrong R let's try 2.2 we can see the pings here and the pings here so the Nexus can ping both rer one and rouer 2 rouer one and rer 2 however will not be able to Ping each other because they need to run a writing protocol they are in separate subnets the Nexus once again is using no switch port to make the interfaces routed interfaces so show run shows us that both of these interfaces are routed interfaces rather than switched interfaces so I'll enable OSF on both the iOS rouers and then we need to enable OSF on the Nexus so to do that the first thing we need to do is enable a license notice what happens when we try and type router OPF 1 rouder question mark we don't have the options that we're looking for so we need to type license grace period so now when we type router OPF 1 it's still not working so we need to type feature and there's a range of features so feature OPF to enable OPF on the switch and notice now when we type rou OPF the command works I could specify a router ID on this router as an example of quadruple 2 and then I I can go onto the ethernet interfaces and just to remind you it's on ethernet 22 and 23 that we need to enable OPF so interface e22 IP rer OPF process one area Z interface 2/3 IP router OPF 1 area Zer we can see on this side we've already got a full relationship so show IP OPF neighbor there's our neighbor relationship on this side we've got a full relationship so show IP OPF neighbor relationship is established show IP OPF neighbor the Nexus has two neighbor relationships both the other rers are designated rouers show IP route we have a writing table what I'll do on router two here is create a loop back of quadruple 3 that should be advertised via OPF and there it is so ping quadruple 3 we can ping the loop back of rer 2 on rouer one create a loop back of quadruple one and we should have that rout in the writing table there you go paying could ruple one ping succeeds so now on the iOS router show IP route shows us the OPF rots that have been learned and we should be able to Ping the Lo back of router 2 which we can we can see in the output here that rer 2 sent a echo reply back to rer 1 so on the Nexus switch don't forget to enable your features notice we've enabled the OPF feature don't forget to enable your licenses show feature shows us the features that are enabled or disabled on the router as you can see here EI JP processes or instances are disabled if we scroll down we have one OPF instance enabled other OPF instances are enabled but they're not run running we have OPF process one running on the router so don't forget to enable Your Grace license and then enable OPF OPF is enabled on a per interface basis you still type rer OPF 1 and give the rer a rer ID as an example so that was an example of how to import and configure a Nexus switch in gns 3 and set up neighbor relationships with Cisco iOS routers I hope you've enjoyed this video if it was of benefit to you please like it and please subscribe to my YouTube channel I wish you all the very [Music] best
