    I have a switch connected to a router and 2 other switches. I have set up 3 VLANs: 1 as the native VLAN connecting to a router and the primary switch, VLAN 2 connecting to 1 switch and VLAN 3 connecting to another switch. I have set up trunking protocols with encapsulation dot1q connecting from the primary switch to the router and the 2 other switches. I have allowed VLANs to be trunked to each other. I have set up the router as a router on a stick with sub interfaces to allow the pings to connect to each VLAN. I have interfaced all 3 VLANs on the primary switch giving them IP Addresses and their own subnets. When I ping from the router from one VLAN to another VLAN, it doesn't work. My assumption is that all of the switches should each have all of the VLANs interfaced with their own IP addresses on the same VLAN subnet as the primary switch. Am I correct in this assumption? So far, the switch with VLAN 2 has only VLAN 2 interfaced with its own IP Address and the same subnet as the primary switch with VLAN 2 interfaced. The same goes with the 3rd switch which has only VLAN 3 and its corresponding subnet with the same subnet as the primary switch.

    This is just a general question regarding IT job retention in the United States. Are IT technicians(Help Desk) or any other IT professionals prone to unemployment and layoffs more than other lines of work? Are IT workers sometimes forced to move if they get laid off from their jobs? I'd like to ask this question to anyone that has some experience in the IT field. Thanks.

    Does the command "Show Ip Eigrp Interfaces" show the connected networks of a router advertised for EIGRP? Where can I find this in "Show IP Protocols"?

    This question is in regards to Spanning Tree Protocol. If one switch has a bridge priority of 32768.1111.833d.1111 and the other switch has a bridge priority of 32768.1111.8339.1111, is 833d selected as the root bridge? Is having a letter as opposed to a number in its MAC address make a switch the rood bridge or a bridge with a higher priority? This is one of the questions that stumped me in ICND2.

    This is just a general question for those that took the current ICND1 or ICND2 test. Is VTP tested at all in either the ICND1 or ICND2 exam? I know it was in the previous CCNA exam before the revision in 2013 and I had trouble with that test question when I took it at that time. The Official CCENT certification guide doesn't cover it, but CBTNuggets covers it briefly.

    Second, If the interfaces on are on a layer 3 switch. Yes, they will able to communicate this is because it has layer 3 technology built int the switch to handle the routing. If you're setting this up on a layer 2 switch. You will have to do inter-vlan routing and it will require a router to do so.

    And layer 3 switches don't require subinterfaces and "router on a stick" correct?

    Nope, once you have VTP configured and ready: vtp mode server and vtp domain-name CCNA and vtp password ICND2 They will start to send vtp traffic and setup if you've configured trunking between the switches. It's always a great idea to save your configs but it's not a requirement...just a great thing to do as a habit.

    Does vtp mode server, vtp domain-name CCNA, and vtp password icnd2 have to be configured on both switches?

    This may be a little bit off topic, but I thought it would be appropriate to ask in this forum. Is the IT economy (primarily Network Administration & Help Desk) booming in warmer climates such as Florida, Texas, & California as opposed to warm & cold climates such as the Northeast? It's probably not a fact, but I imagine that with what I learned about ESD and temperature controlling server rooms, it's probably easier to maintain computer equipment in warmer climates. I know that since I live in New York City, the only job offer that I can get is working at Staples even with my college degree, A+, and Network+. I always want to be on the road troubleshooting computers, and I do see a few vans in my area that have signs all over the vehicle stating that they do computer upgrades. I believe that you see a lot more of these types of businesses down south and in California. I also feel that those companies would make me get experience working with computer parts and software & know that I have at least some type of formal training as opposed to just A+ and Network+. Anyways, I just thought I'd share that with you guys. Hope to hear some responses.

    3 more questions:

    1. Once I configured the appropriate information in switch 1 (such as VLANs) to be used as updates to switch 2 while on vtp mode server, does switch 1 need to have its configuration saved in startup config in order for the changes & vtp updates to take place in switch 2?

    2. If I issue a Network command for OSPF with network 192.168.2.1 wildcard 0.0.0.0 (that ip address is connecting out of a router's fast Ethernet port) or network 192.168.2.0 wildcard 0.0.0.3 (representing 3 computers for that network), does the neighboring router still accept either update?

    3. If one switch has it's speed & duplex hard coded (speed 100 duplex full), does the connecting switch set to autonegotiate receive its info at half duplex? Or does it receive it's duplex if both are set to autonegotiate?

    Thanks

    Hey guys, great videos once again! I have a question about commands related to Trunking and VLANs. First, does the command "switchport mode trunk" have to be implemented in both switch's trunk ports for the trunking to take place? If I have one switch on fast Ethernet 0/1 have "switchport mode trunk" enabled, does the connecting switch on its fa0/2 need to have "switchport mode trunk" typed in as well? Also, when I set up an IP address for a VLAN interface, are VLANs separated by network or subnet? For instance, if I have a vlan 1 interface set up for 192.168.50.1 255.255.255.128 and another vlan 2 interface set up for 192.168.50.130 255.255.255.128(assuming these are not layer 3 switches), can devices connected with those vlans communicate with each other?

    Thanks again for these videos! I'm also watching CBTNuggets for information.
