How to Configure L2-VLAN on JUniper EX Switches.mp4

hello everyone today we're going to see about configuring layer 2 VLANs on the e^x 4200 switch from juniper this is the topology that we want to go ahead and have configured on our e^x 4200 switch the first gig ether interface GE 0 0 0 is going to be configured as a trunk interface as it connects to an external switch this trunk interface is going to carry all the VLANs that we configure on this particular switch the trunk interface is that interface which can carry more than one VLAN the GE 0:01 interface is going to be connected to the printers segment we're going to separate this from the rest of the network using VLAN 10 the end-user machines are going to be placed in their own separate VLAN of 20 and they get connectivity through the GE 0:02 interface of our switch finally we have our servers which are going to be placed in VLAN 30 this is on the GE 0:03 interface so let's go ahead and take a look at the actual switch itself and the configuration that we need to perform on this switch here we are on the switch and we can go ahead and confirm what VLANs are on this switch by giving a simple show VLANs command as can be seen all interfaces on the switch are in the default VLAN which means they are just untagged let's enter the configuration mode in the configuration mode we will enter the VLAN hierarchy of the Junos system inside VLANs let's go ahead and create three groups one for printers one for servers and one for the end-users so as can be seen we have now created three groups of real ends the printers which are in VLAN ID 10 end users VLAN ID 20 and the servers which are on VLAN ID 30 we now need to apply these real ends on their respective interfaces so let us first exit from this hierarchy of VLANs we will now enter the interfaces hierarchy in the interfaces hierarchy let us first go ahead and configure the regular interfaces the interface which is GE 0 0 1 the interface GE 0 0 2 and the interface GE 0 0 3 we will start with GE 0 0 1 we set the port mode for these interfaces as access we now mention that this particular interface is going to have the VLAN of printers as a member so now this interface will inherit the VLAN 10 that was previously configured under printers we now configure the second interface which goes to the end users and finally we configure interphase GE zero zero three this takes care of the regular interfaces which are connecting our switch to the segments of the printers the end users as well as the servers we also need to configure one more interface which is the GE zero zero zero interface and mention that this is a trunk interface which connects to a different switch and it's going to carry these particular VLANs that we have already defined so as can be seen this particular interface is in the port mode of trunk and it has three different VLANs as its members we now need to commit this configuration into Juno's so that it is applied across the interfaces we will now go ahead and exit from the configuration mode and once again from the operational mode let us verify what we lands are now available as can be seen from here we have the interface of GE zero zero zero as well as zero two in the end-users VLAN printers which has again the zero zero zero interface and the zero zero one and the servers which is zero zero zero and the zero zero three this completes our configuration for the basic VLANs that we have over here and as can be seen we have completed our interface configuration GE zero zero zero has the members servers and users and Printers GE 0 0 1 is only printers zero zero two end-users 0 0 3 only servers and finally we have the VLANs which mention the ID numbers versus the names that's all for configuring the layer 2 VLANs on the juniper ax which and I thank you for watching
