CCNA Routing & Switching Packet Tracer Labs

welcome to this free CCNA packet tracer practice lab you can download the lab file from the link in the description if you like these labs please consider supporting me via my patreon or the cryptocurrency options in the description also please subscribe to the channel for more labs like this in this lab we will troubleshoot inter VLAN routing in these 2 small networks which we just configured in the previous lab I have made one miss configuration on each networking device see if you can find and fix the errors first let's test the network of PC one switch 1 and PC 2 I'll try a ping from PC 1 in VLAN 10 to PC 2 in VLAN 20 ping 1002 10 it fails let's investigate on switch one enable show IP interface brief looks like the VLAN 10 and VLAN 20 interfaces have the correct IP addresses configured show VLAN brief here's our problem the fastethernet 0/1 interface to which pc one is connected has been placed in v-line 11 not VLAN 10 let's put f01 into the correct VLAN and see if that solves our issue coffee/tea interface f01 switch port access VLAN 10 I'll delete VLAN 11 also since we're not using it exit no VLAN 11 do show VLAN brief ok our VLAN configuration looks good let's try that ping from pc1 again ping 1002 10 this time the ping is successful so we have fixed the issue on this network now let's test the issue on the next network I'll try to ping from PC 3 in VLAN 30 to pc 4 in VLAN 40 ping 1004 10 the ping is not successful so let's find the issues there should be one issue on our two and one issue on switch to according to the lab instructions I'll investigate on our two first enable there could be a few problems here like incorrect IP addresses or encapsulation dot1q configurations on the sub interfaces I'll use show running config this time so run our interface Gigabit Ethernet 0 0 is not shutdown and 2 sub interfaces are configured they are assigned to the proper VLANs 30 and 40 however look at the IP address on the dot 30 sub-interface the VLAN 30 subnet is 10030 / 24 so we should fix that Koff t interface g0 0.30 IP address 1003 1 255 255 255 0 do show IP interface brief ok now it has the correct IP address so we fixed the issue on r2 let's go to switch to next enable so the correct configuration on switch 2 should be f01 connected to pc 3 in VLAN 30 and f0 to connected to pc 4 in VLAN 40 and g0 one connected to r2 should be a trunk let's check show VLAN brief fast ethernet 0 1 & 0 2 are in the correct VLANs show interfaces trunk however nothing appears with the show interfaces trunk command show run there's our problem Gigabit Ethernet 0 1 is configured as an access port actually in the previous show VLAN brief command you could see it in VLAN 1 that means it won't pass data from either VLAN 30 or VLAN 40 let's properly configure it as a trunk compte interface g0 1 switch port mode trunk do show interfaces trunk ok now we can see the gig 0 1 interface is a trunk and let's check that VLAN configuration once more do show VLAN brief it is also no longer listed in VLAN 1 so our inter VLAN routing in this network should be properly configured let's try that ping again once more from PC 3 to PC for ping 1004 10 okay this time the ping works we have successfully fixed the problems that's all for this lab thank you for watching I hope this lab and video have been helpful for you please subscribe for future labs like this which will be released weekly if you have requests for any specific labs let me know in the comments section if you want to support my channel I accept the Bitcoin and aetherium donations via the addresses in the description I am also a great verified publisher and accept bat or basic attention token donations in the brave browser
